4 Helpful Tips for system installation and setup
a. Select digital input to get better image and avoid image position shift.
b. If 4k signal connection distance is more than 10m, please select a certified HDMI cable to avoid
unstable signal connection. Usually [High Speed HDMI + Ethernet] cable will be better.
c. The quality for signal adapter or converter, such as HDMI to DVI adapter and DisplayPort to HDMI
converter, may downgrade the signal quality and cause issue. Please select qualified ones.
d. If user can see blue background image with [Power Saving Mode] message, it means the signal
connection between projector and GeoBox is OK but no input signal detected by GeoBox. Please
check signal source or replace a different input source to test.
e. If user can’t see [Power Saving Mode] message or splash screen, please check the connection
between GeoBox and projector. User can connect to a monitor to check the output from GeoBox.
[Loop out] port is for raw signal daisy chain connection and is not a output to projector.
f. The output resolution setting shall be the same as projector native resolution to get the best video
quality. After geometry alignment, this output resolution can’t be changed. Otherwise, geometry
position will be shifted and required further adjustment.
g. In the application with short throw ratio projector on curved screen, it is possible that the image
location is beyond the maximum adjustment range in manual adjustment. In this case, Gwarp PC
tool is required to double the adjustment range.
h. During installation setup process, please apply FHD signal to the system for easy setup. After
finish the setup, user can select optimized EDID from OSD menu to get optimized video quality.
i. The optimized EDID resolution should be the final resolution after edge blending. For instance, if
user uses three XGA projectors for edge blending with 250 overlapped pixels, then the best signal
for this setup will be 1024*3-250*2=2572. It means 2572*768 will be the best signal resolution for
this setup. User can customize EDID with this resolution in GeoBox. Some PC may not be able to
output the same custom resolution. In this case, user needs to set PC output resolution as close
this timing as possible. GeoBox can support none-VESA standard input timings.
j. In addition to the resolution settings, user needs to provide a content with the same aspect ratio
as screen to ensure no distortion on the screen.
k. To reset all projectors before edge blending to get the same settings in all projectors.
l. To turn off auto keystone function to avoid image shift.
m. In order to avoid interference among multiple GeoBox during the installation, user can set ID
number for each GeoBox through [Options] Menu. Press number keys in Remote Controller for
the control of multiple GeoBox:
850: simultaneous control for all GeoBox
851: control GeoBox ID No. 1
853: control GeoBox ID No. 3
n. OSD Lock / Unlock: When continuously press [OKD Lock] key on Front Panel or [Menu] key in IR
Remote Control for 5 seconds, the OSD function will be locked to prevent from setting change by
G-602
9
negligence. To press [OSD Lock] key or [MENU] key for 5 seconds again, it will unlock OSD and
user can manipulate the OSD again.
o. [Image Setup] menu will not be activated if the input source is not from VGA.
p. Please reset GeoBox before any new application to avoid unexpected settings in the system. If
deeper reset is required, user can turn on GeoBox and press both [Menu] + [Pattern] key on front
panel and power on GeoBox again for 5 seconds. It will reset the system
q. To set [Menu Time Out] to “0”, the OSD will appear till the OSD Menu has been turned off
manually or system input timing change.
r. Default Internal Grid Pattern represents 32x32 pixels no matter which input resolution is selected.
s. Only HDMI-A input port can provide HDMI raw signal loop out for daisy chain connection. This
loop out signal has no any processing.
t. When [Gwarp] PC tool is used, user needs to save the setting into GeoBox through the OSD
menu: [Anyplace] [Gwarp Pro] select [UserMap 1-10] to save the settings. Then PC can be
removed.
u. When Power Off/ON GeoBox, it will maintain the final settings.
v. User needs to save the final setting into [Profile] under [Options] menu for long tern stored inside
the system. Even the system is reset, the [Profile] settings will be kept without change.
w. Continuously press PATTERN button, internal test pattern will show different colors for easy
installation: White—Red—Green—Blue—Blank. When in “Blank”, user can see OSD and the
image from signal source. In this case, PC test pattern can be applied.
x. Please use INFO hot key on front panel or remote controller to check the input and output timing.
The indicators on the front panel will show the input/output connection status.
y. User can set black background while no input signal is detected and input timing change under
[Options] [Accessibility] menu.
z. Below hotkeys are available in remote controller:
[Warp] geometry alignment, [Video wall], [Edge Blend], [Info], [CH A/B] switching.

5 Applications case study
5.1 Case A: Conventional curved screen edge blending
a. No PC is required.
b. To feed signal from any signal source to G-602 HDMI input port and connect to the 2nd G-602 through
loop out port. No HDMI splitter is required. The latency among these G-602 will be only few lines. The
max daisy chain connection can be up to about 12x G-602 . However, it will depend on the HDMI
cable length and quality. User needs to check in advance.
c. The maximum input resolution can be up to 2560x1600/3840x1080 @60Hz or 3840x2400 @30Hz to
get the best result in multiple projector edge blending.
d. User needs to do geometry adjustment and warping function to align the images onto curved screen
and let the images between two projectors have the same grid size and with necessary overlap pixels.
e. After geometry and warp adjustment, user can apply Video Wall function in G-602 to split the image,
crop the correct area and assign to each projector.
f. The last step is to do edge blending to combine the images into one seamless screen.
g. If the application is in dark environment, to do [Offset] compensation is required to eliminate black
level color difference between edge blending area and none edge blending area.

(Flight simulation system with 3 projectors on half Dome)
(Cylindrical curved screen edge blending up to 360 degrees with 6x projectors and 3x G-602)
5.2 Case B: Flexible display in edge blending system
1. 4 projector edge blending can be configured as below:
2. 4 projectors edge blending into one content
3. Independent two discrete contents (2+2)
4. Two projectors edge blending and one single projector display with original aspect ratio.
5. If user can add one G-101 at the front end, user can implement PIP/POP across entire display
screen.
6. User can save the setting into Profile and recall at any time.
7. If discrete 4 projector displays is required, G-700 model is required.
G-602
12
5.3 Case C: High resolution Edge Blending
a. Usually, each full HD signal can feed up to 3- 4x projectors for 10m screen and still keep acceptable
video quality (it will also depend on the watching distance).
2 projectors as one edge
blending system to
provide 2+2 displays
2 projectors edge blending
+ one projector display

G-602
13
b. Many video cards can easily provide upto 4x 3840x1080 outputs for G-602
c. Each PC output is fed into one G-602, then to two projectors. 4 outputs will be fed to 8 projectors.
d. If the overlap pixels is 250, then it can provide a video wall with 13,610x1080 output resolutions.
e. If the watching distance is 5m, the video pixel pitch can be about 5mm. In this case, the total screen
size can be up to 13610x5mm=68m and still keep acceptable video quality.
f. The display card should have the function to set overlapped pixels between two output ports. In the
case of four output display card, PC should be able to set overlapped pixels between output P2/P3,
P4/P5 and P6/P7. The overlapped pixels should be up to about 20%-25% of the output resolution. The
rest overlap areas (P1/P2, P3/P4, P5/P6, P7/P8) can be set by GeoBox.
g. If the display card doesn’t have above mentioned overlap setting function, then user needs to create a
content with some overlapped pixels up to about 20%-25% between outputs.
h. GeoBox can do geometry alignment, split the image, assign image for each projector and capture the
right size of the image for edge blending.
i. If one output can be connected to two G-602 through daisy chain connection, one 3840x1080 output
can be connected to 4 projectors and total projectors will become 16. If one PC output can be daisy
chain connection to 3x G-602, then 4 output will connect up to 24 projectors and the total video wall
can be more than 50m and still with good video quality.
j. The advantage for this kind of application is high output resolution. However, it still has some
limitations.
The major input source shall come from multiple PC, PC with multiple windows disply card or
media player with cascade function (such as Bright Sign).
The PC shall have enough processing power to handle multiple output windows. More video
output ports from display card will occupy more PC resource.
Different playing contents (compressed types) may also require different CPU resource. User
needs to test before implement this kind of display system.
The output aspect ratio will be changed depending on the display system. User needs to take
care of the aspect ratio in the source content in advance.
k. Edge blending will increase the total resolution. Usually, the video quality will be good enough for most
of the applications if output resolution in each projector can reach XGA/WXGA resolution.
l. User can connect with other signal sources like Blue Ray or Media Player to other input ports in G-602.
By selecting different input ports and applying different GeoBox settings, it will provide different display
modes. For example, for 3 projector edge blending, user can set all three edge blending, two projector
edge blending and one has discrete display or each projector has independent content.
m. GeoBox can reduce the CPU loading in PC and reserve more CPU resource to handle interactive or
other operation without image lag.
5.4 Case D: “L/M” shape video wall with edge blending
Below is example of the application in restaurant with “L” shape video wall:
a. 3x WXGA projectors: two projectors edge blending on the front screen and another projector is located
at side wall.
b. The image is met at the corner. It is not necessary to do edge blending at the corner. User just needs to
G-602
14
do geometry alignment to let the image meet at the corner.
c. User can use Video Wall function to split the image into 3x (using ZOOM function) and use PAN and
OVERLAP function to capture the right size of the image and assign to each projector.
d. Three projectors should have the same image captured size to avoid different scaling factor in the
projectors. It can be adjusted through Video Wall Overlap function.
e. To do edge blending on the front two projectors and the image in side wall only needs geometry
alignment and Video Wall setting.
5.5 Case E: Irregular curved display or edge blending
User can use G-602 to do manual adjust and achieve curved display for most of regular curved screen.
Once the screen has special shape, then to use Gwarp PC tool for the alignment may be necessary.

projector in the side wall.
GeoBox can combines all image
together with the right scaling factor
into one seamless image.
Three walls with 8 projectors. 4
projectors executes edge blending on
“L” wall and 4 projectors executed edge
blending on floor. GeoBox combines all
images with the right scaling factor into
one seamless image.

5.6 Case F: Active 3D and passive 3D display
User can use one G-602 as 3D de-multiplexer to decode HDMI 1.4 3D signal or active 3D frame
sequential 100/120Hz signals for passive 3D display using two projectors. This kind of passive 3D
application can be expanded to bigger screen through edge blending with more GeoBox and
projectors. User can also increase brightness in 3D system through image stacking with more
projectors.
User can convert Nvidia 3D Vision 1080p 120Hz 3D signal and 1080p/24Hz frame packing 3D from
Blue Ray into 720p/XGA 100Hz/120Hz frame sequential 3D signal for DLPLink 3D Ready projectors.
Passive 3D will be the best solution for large scale 3D display through edge blending. If applying
multiple projectors in active 3D display, user may meet active 3D synchronization issue. Passive 3D
will have no synchronization issue and will be more comfortable than active 3D.

6 Internal Grid Pattern for Geometry Adjustment
To press [PATTERN] key in Remote Controller or at front panel, it will show internal grid pattern. By
continuously pressing [PATTERN] key, different color grid patterns will appear cyclically from White
Red Green Blue Blank. If user wants to disable grid pattern, please use Exit key in
Remote Control or Menu key in Front Panel. Each grid pattern is 32 pixels in width and height. User
can calculate the overlap pixel via the number of grid pattern and calculate the pixel number.
This internal pattern can’t co-exist with OSD menu. During geometry adjustment, user needs to
select adjusting item, then click [Enter] to pop-up grid pattern. If user wants to use external grid
pattern from PC or other signal sources or see OSD menu instead of internal grid pattern, user can
continuously click pattern key to show it. A flashing indicator at the adjusting point will appear. User
can see real time grid pattern change during the adjustment. It is recommended to connect through
digital interface (HDMI or DVI) to the projector to avoid any position shift after installation.

10 Video Wall Setting
The purpose for Video Wall Setting is to determine the display Matrix, split the image and assign each
GeoBox/display device to the right location in the matrix. The overlap pixel between two images can also
be adjusted pixel by pixel so that the video wall can meet the requirements in different application
environment. The maximum video wall can be up to 15x15 matrix display with overlap up to 900 pixels for
edge blending.
10.1 [Zoom]: split the image
Note: If the input source is 3840x2160 and Zoom is H=2, V=1, the Overlap setting value will have limitation
or show abnormal image. Please apply 3840x1080, 3840x800 or 3840x768 in edge blending. It will have
no limitation.

10.3 [Overlap]: to set image overlap pixels
In more than 3 projector applications, if the overlap region sizes are not the same due to
installation position limitation, the overlap value will be also different.
Please contact us for this kind of irregular overlap condition.
User can use Video Wall overlap setting to fine-tune the image in overlap region. It can
Note: If the input source is 3840x2160 and Zoom is H=2, V=1, the Overlap setting value will have limitation
or show abnormal image. Please apply 3840x1080, 3840x800 or 3840x768 in edge blending. It will have no
limitation. Another method is to set ZOOM H=3 and PAN: V=2 to select the center image, then increase
Overlap Top Edge & Bottom Edge to crop the image you need.
10.4 Example for three projector edge blending

a、 An Excel Spread Sheet can be provided for the calculation of the Video Wall Overlap setting value.
b、 For dual projector edge blending, user can increase [Overlap] value in each channel at the same
time. Then user will see the overlapped images to come closer till two image 100% match
together.
c、 For dual projector edge blending, user can use below equation to calculate overlap pixel.
Assumption: Input signal:1080p, G-602 output to projector: XGA, Overlap 224 pixels (7 grids)
Overlap value=(1920/2)/(1024-224/2)x(224/2)=118 pixels.
11 Passive 3D Display
11.1 System Configuration
GeoBox will decode 3D format from all kinds of 3D video sources, including Blue Ray DVD, STB, Media
player, Game console and PC… 3D signal will be decoded by GeoBox into signals for Right/Left eyes.
The signal needs to be displayed through two projectors. Each projector will display signal only for right
eye or left eye. User needs to set a polarized filter in front of the projector and also wears polarized
glasses. The glasses need to match the polarized filter in front of the projectors so that the right eye can
only see the scene for right eye and the left eye can only see the scene for left eye. Silver 3D screen is
also required to preserve the polarization of the light for 3D display. It is possible to use optic spectrum
method from Dolby, Infitec or Omega Optical to allow 3D displayed on normal 2D screen.
After geometry alignment and [Zoom]

After video wall Overlap adjustment and
apply Edge Blending: No more double
image in overlap region and smooth the
uniformity of the color and brightness.
G-602
23
11.2 System installation and setup
a. GeoBox should not be installed at side of the projector where the ventilation hot air comes out.
b. Two projectors can be put side by side or top/bottom. Closer position will reduce geometry
adjustment range and reduce the loss of the image resolution and brightness. Please make sure
hot ventilation air will not affect the other projectors. Isolated board between two projectors can be
added if necessary.
c. Set higher output resolutions (such as FHD) from 3D signal source and connect to any input of
GeoBox. GeoBox will decode and distribute the signals for two projectors.
d. Each GeoBox output is connected to one projector for right/left eye display.
e. Install polarized filter at some distance from projector lens to avoid thermal damage (at least 5-10
cm).
f. Setup the polarized filter and glasses so that right/left eye can only see the scene for one eye.
g. Use geometry alignment function to align the images from two projectors completely matching
together. Please place the polarized filter in front of the projector before [4 Corner] adjustment
because polarized filter will affect the direction of light beam from projectors. Some deviation is
allowed for 3D display but will affect the performance in 2D display. A good alignment will give double
brightness for the projection in 2D display. For a good double brightness application, two projectors
should be placed as close as possible and the screen must be flat or smooth curve.

If still can’t verify “R” & “L” characters in both eyes, please check below again:
Is the screen for 3D display?
Are the Glasses and polarizers the same types and paired for the RH & LH eyes?
Please check from [Output Format] menu and make sure [Right Eye Frame] is connected with RH
eye projector and [Left Eye Frame] is connected with LH eye projector.
Is the Blue Ray player PlayStation set to [Auto 3D] or [1080p frame packing] mode for 3D signal
output?
If Side by Side or Top-Bottom 3D formats are used, please check the aspect ratio in video source
output to make sure GeoBox will receive full screen image.
Is there any HDMI or signal source compatibility issue and only one projector shows image?
Are the HDMI cables qualified and the length not too long?
After the above procedures, apply 3D signal source and wear 3D glasses, user can enjoy the most
comfortable and healthy 3D system. It is the best solution for children with minimum harm to the eyes.
12 Active 3D applications
For DLP-Link or Nvidia 3D Vision active 3D display, user needs to provide 100/120Hz signal to
projectors integrated with either DLP-Link 3D Ready or Nvidia 3D Vision capability. If multiple projectors
are used, shutter glasses will only synchronize with one emitter among these 3D Ready projectors.
G-602 can support 100/120Hz frame sequential 3D signal up to full HD and also 1080p 24Hz frame
packed 3D format from Blue Ray player, execute geometry warp, edge blending or stacking for these
signals and output 720p or XGA 120Hz signals for active 3D display.
In multiple projector active 3D applications (edge blending or stacking), please select DLP projector with
“3D Ready” function. The projector should be able to select [3D enable] and [3D Sync] functions
separately because only one projector in edge blending can enable [3D Sync] and all the other
projectors shall Enable 3D but turn off [3D Sync] to let the glasses only synchronize with one signal.
Please note that after edge blending in active 3D system, it will not support side by side and top/down
3D signal because once this kind of 3D signals have been gone through geometry alignment, the image
location will be also changed. It can’t show correct 3D effect. Please also note that multiple projector
active 3D system may meet R/L inverse image issue. User needs to swap R/L channel through glasses
or projector every time.
The major functions of G-602 in active 3D applications are:
Activate [Identify] menu to show
“R & L” characters on the screen
simultaneously to verify the final
3D settings in the system.
RH eye should see only “R” and
LH eye should see only “L”.

a. Geometry adjustment to fit image on to curved screen.
b. Edge blending to enlarge the display with multiple active 3D projectors.
c. Image stacking to enhance the brightness using multiple active 3D projectors.
d. Format conversion: Convert Blue Ray 1080p 24Hz frame packed and PC or Nvidia 3D Vision
1080p 120Hz signals for active 3D display.
e. GeoBox can also convert 1080p 120Hz input into 1080p 60Hz output for passive 3D or 2D display.
12.1 Procedures for active 3D Setting
a. To select the output resolution in GeoBox to XGA (for XGA projector) or 720P (for projector native
resolution larger than 720P) through front panel or remote control hotkeys.
b. To set 3D output format at [XGA 120Hz output] or [720P 120Hz output] under 3D Properties menu.
c. If user selects other output resolution except XGA or 720P, [3D Ready] menu will be grayed out
and user can’t select 120Hz output.
d. Projector needs to have 3D Ready DLP Link or Nvidia 3D Vision function. This 3D function needs
to be open while playing active 3D.
e. It is possible for user to see inverse image in R/L eyes’ image. User need to swap R/L signal
through projector internal function [3D Sync Invert] or active 3D.

G-602
27
13.1 Geometry adjustment range
a、 The adjustment range is calculated based on the percentage of output resolution in GeoBox
setting. Therefore, higher output resolution will have more adjustment pixels.
b、 Under XGA output resolution, the adjustment range are as follows:
--[2x2 Corner] adjustment in one side: Horizontal: 150 Pixels, Vertical: 100 pixels
--[3x3 curved] & [5x3 Curved] adjustment: Horizontal: 150 Pixels, Vertical: 100 pixels
--Maximum adjustment range in one side: Horizontal: 300 Pixels, Vertical: 200 pixels
--Maximum adjustment range in both side: Horizontal: 600 Pixels, Vertical: 400 pixels
c、 Under WXGA & 1920x1200 output resolutions, the adjustment range are as follows:
--[2x2 Corner] adjustment in one side: Horizontal: 300 Pixels, Vertical: 200 pixels
--[3x3 curved] & [5x3 Curved] adjustment: Horizontal: 300 Pixels, Vertical: 200 pixels
--Maximum adjustment range in one side: Horizontal: 600 Pixels, Vertical: 400 pixels
--Maximum adjustment range in both side: Horizontal: 1200 Pixels, Vertical: 800 pixels
d、 Gwarp PC tool has double adjustment range than manual adjustment.
13.2 Procedures for geometry alignment
a、 User can select the procedures based on different application and conditions. If the
application is for flat screen, then [2x2] alignment will be quicker and enough.
b、 If curve alignment is required or the flat screen is not flat enough, user can use [2x2]
alignment to draw the corner positions to expected locations. Then apply [3x3] alignment to
align the outlines of the image to the required positions following with [5x3] & [9x5] alignment
to do position fine-tune. User needs to strictly follow this procedure for edge blending to get
uniform display across entire screen.
c、 After finish [5x3] and [9x5] alignment, user can go back to [2x2] alignment to fine-tune the
corner positions.
d、 After [9x5 Curved] alignment, it still can’t meet expected result or manual adjustment range is
not enough, user needs to apply Gwarp PC Tool for the geometry alignment.
e、 [Gwarp] PC tool can apply [5x5], [9x9] and [17x17] grid pattern adjustment. It also has double
geometry adjustment range.
User can see the grid location for
geometry alignment on the screen.
User can use remote controller or front
panel keypad to change grid location.
When adjusting each grid, the other grids
will maintain at the same location.
G-602
28
13.3 [Reset] in geometry alignment
a、 After finish [3x3], [5x3] & [9x5] alignments, user can go back to [2x2] alignment to fine-tune the
corner positions and will not affect [3x3] and [5x5] adjustment result.
b、 If user finishes [5x3] & [9x5] adjustment and go back to [3x3] menu, then it will reset the
adjustment and only keep [3x3] adjustment result.
c、 If user press [Reset] key in [3x3] adjustment, all the adjustment in [3x3], [5x3] & [9x5] will be
reset and only [2x2] will be kept.
d、 Once implement [2x2] alignment, the image corner position will be changed and all other curve
alignments will keep the same.
13.4 How to increase the accuracy of geometry alignment
a、 [9x5 Curved] will cut the horizontal image into 8 sections and the image in each section can be
independently adjusted. In different output resolutions, there will be different pixel number in
each section: XGA: 1024/8=128, WXGA: 1280/8=160, 1080p: 1920/8=240. Usually, it is
enough for most of the curved screen edge blending.
b、 If the overlapped area between two adjacent projectors has the same or multiple number as
above, the manual geometry alignment for grid overlap will have less flexibility. User can
increase or decrease one or two grids (32 or 64 pixels) in overlap area to increase the flexibility
for accurate alignment between adjacent projectors.
c、 [9x5 Curved] alignment for two projector edge blending area as an example (in 1024
resolution):
G-602
29
If the overlap is 256 pixels (25%) in XGA resolution, total adjusting points are 15. User will have
less adjustment flexibility. If increasing two grids (64 pixels) to 320 overlap pixels, user can have
30 adjusting points to get more accurate geometry alignment. It can align the images from two
projectors on curved screen with good quality without Gwarp PC Tool.
d、 Below is the list for the accuracy of geometry adjustment in different overlap pixels:
GeoBox output resolution 1920*1080 1280*800 1024*768
Min. adjustment flexibility 240/480/720 320/480/640 256/384/512
Max. adjustment flexibility 352/608/832 224/256/384/416/544/576 192/320/448/576
13.5 [Edge Blend]
a. Edge Blend is to merge the images from multiple projectors to become one seamless image.
b. The scaling factor between two adjacent images shall be the same. Otherwise, it will become
blurred. It means the image size under the same resolution should be the same.
c. Geometry alignment is required before edge blending:
To let the images from different projectors has the same.
To let the grids in overlap region overlap together.
d. Sub-menu under [Edge Blend] menu
[Edge]: select the right edge and set overlap pixels
[Gamma]: select correct gamma for overlapped area and [Offset] compensation area to
eliminate banding effect.
[Offset]: to do black level uplift in non-overlapped area to compensate light leakage in
projectors.
[Corner]: to do precise [Offset] location alignment.
[Shift]: shift the location in edge blend area. In some case, it may help color fine-tune. [Shift]
can also do [Edge Mask] for non-overlap edges with black background.
[Color]: to do discrete color adjustment for individual projector.
13.5.1 [Edge] selection and settings
a. [Edge] is to select the edge for edge blend and set overlapped pixel number.
b. GeoBox can do edge blending at any edge.
G-602
30
c. Maximum edge blend pixels are 900. If over this number, please consider using image stack or
change aspect ratio in projector to shrink projection image. User can also reduce edge blending
area by geometry alignment.
13.5.2 [Gamma]: Color correction in edge blending area
a、 Different projectors may have different gamma curve. Different “Display mode” in the same
projector will also have different gamma curves. These gamma curves will affect the final video
result in edge blending area. The common issues are gray or color banding effect. These issues
are more significant in pure color or white back ground display.
b、 [Gamma] is to select the right gamma curve for edge blending area.
c、 If color difference in the projectors, user need to adjust the color difference in the projectors to
reduce the possible banding effect in edge blending area due to color different among projectors.
d、 [Gamma] function is not functional when [Edge] setting is not executed.
Please note:
Color indicating lines will appear when
set edge blending pixels.
User only needs to adjust the color
indicating lines to match together
(green to green, red to red). There is no
need to calculate the overlapped pixels.
User needs to select correct edge for edge
blending.
For 3 projector edge blending as example:
To select [Left Edge] for RH projector
To select [Right Edge] for LH projector
To select both [Right Edge] & [Left
Edge] for center projector.
Three sub-menu under [Gamma]:
[Transition]: To set edge blending area
gamma value.
[Gain] gamma: To change gamma curve
in each projector.
[Offset] gamma: To balance black level
Offset and normal image brightness.
G-602
31
a、 User needs to press [Enter] key after selecting gamma value to see the result.
b、 Banding effect in edge blending area is mainly related to projector gamma curve accuracy and
color settings. The projector should have the same gamma setting and [Display Mode].
c、 Please disable [Dynamic] color or [Brilliant] color function in the projectors. These functions will
change gamma curve based on the content and affect final edge blending image quality.
13.5.3 [Offset]: Black level uplift
If edge blending is performed under dark environment, due to light leakage in projector optical
system, user will see gray area in overlapped area. This gray area can’t be fixed by signal
processing. The only way is to uplift the black level in non-overlapped area to reduce the black level
difference. [Offset] function is to balance black level in the display under dark environment.
Left picture is to show projector light leakage
under dark environment. In overlapped area,
the offset value is the sum from two projectors.
Low contrast ratio projector will be more
serious. Higher native contrast ratio (not
dynamic contrast ratio) will be better.
Left picture is to show banding effect in edge
blending area.
This issue is related to many factors:
Screen: gain value
Projector: gamma and Display Mode.
Usually, DLP projector will get better result.
Signal content: To avoid pure color or pure
white color content. Multimedia is the best.
Overlap range: too small overlap range will
be easier to see banding effect. 15%-25%
with more than 40 cm is recommended.
When adjusting black level, [Offset] value will be
applied to complete color range and reduce image
contrast. [Offset] gamma adjustment can avoid
this issue and let [Offset] adjustment only affect
black level but not complete image. User can also
use this function to balance the brightness in edge
blending between two projectors.
G-602
32
13.5.4 [Corner]: Adjust [Offset] compensation position
The starting point for this Offset is based on Edge blend borders. The projector light leakage area
is from the original projecting area before geometry alignment. Therefore Offset borders may not
be the same as light leakage area. User needs to use [Corner] menu to align the border lines of
Offset adjustment.
a、 After set [Offset] value in [Non-Transition] area, user can reduce the black level offset difference
but user will also see light bar near edge blending border.
b、 The maximum range for the corner adjustment is 300 pixels. When user installs the projectors,
please make sure the projector projecting area border to be as close as actual edge blending
border. The maximum difference should be under 300 pixels.
c、 Projector display imager, such as DMD, LCD and LCOS, will have some image borders due to
active display window is not at full range of the imager. In dark environment, viewer may see this
kind of black level uplift in image borders. It is outside active display area and can’t be corrected.
[Non-transition] and [Transition] offset
adjustment menu。
Under each menu, user can adjust RGB
offset value to balance the color difference.
Usually, user needs to raise RGB offset
value in Non-transition area (about 20-40 in
DLP and 50-70 in LCD projectors).
User can adjust color in [Transition] area
but can’t reduce the level. It is light leakage
from projector.
[Corner] can adjust the positions for black
level [Offset] borders through change the
end points of the borders.
User can adjust the top and bottom points
to get accurate positions.
Maximum adjustment range is 300 pixels.
G-602
33
13.5.5 [Shift]: Edge blending area shift & Edge mask following geometry position
13.5.6 [Color]: Individual projector white balance and color correction
The [Color] adjustment can be applied to individual projector for white balance and color difference
correction through separate RGB Gain and Offset adjustment. It will be very helpful in projector system
because projector may have color difference, lamp brightness decay and lamp replacement issue.
Through this [Color] adjustment, it will improve the video quality in edge blending.
[Shift] is to shift the whole edge blending
area to other location. The width of the
edge blending area will remain the same
and only change the position. This is to test
the effect of banding effect and select the
best location of the edge blending.
Another function for [Shift] is to execute
[Edge Mask] on the edges of non-overlap
region.
The maximum adjustment range is 500
pixels in each edge.
If users still see some deviation in the border
line. It means the geometry alignment in
overlapped area border line is not accurate
enough. Please correct this issue from
geometry alignment.
G-602
34
In edge blending procedures, firstly, user needs to adjust the color from projector. If it is still not enough,
user can use [Color] function to do further adjustment. Please note that, any color adjustment will reduce
the color dynamic range. User needs to check the result with full range color image.
13.5.7 [Mask]: Edge mask without changing image aspect ratio
There are two Edge Mask functions in G-602. One is in [Shift] and another one is in [Mask]. The difference
between these two functions as follows:
1. The edge mask position in [Shift] will follow geometry alignment result.
2. The edge mask position in [Mask] is nothing to do with geometry alignment result. It will
be decided by 8 points around the edge. When user changes the location in each point, it
will result many irregular shapes of edge blending.
3. User can combine edge mask function in both [Shift] and [Mask] functions to get more

14.5.2 Frame Lock and Smooth Switching Mode
[Frame Lock] will ensure the input and output frame rate synchronize together. When the application
uses multiple GeoBox, the signal in each GeoBox will also have better synchronization without frame
tear. However, when the input timing change or video source have been changed, the output signal
will be broken temporarily and it will cause projector to re-search input source and no video image will
be displayed during that time. If user wants to eliminate this kind of waiting time, user can [Disable]
frame lock to maintain continuous output in GeoBox while input source or timing change. This kind of
Smooth Switching Mode is only available when the signal change is in same vertical frequency, such
as within NTSC or Pal. If the input timing change is between NTSC or PAL, there will be still temporary
signal break and the projector will re-synchronize the input signal again. When Frame Lock is
[Disable], GeoBox will shorten the time for mode change. GeoBox will also conduct HDCP verification.
This verification process will also take some time. Therefore the time for mode change may be
different in different cases.
14.5.3 [Box ID]

GeoBox
14.6 [EDID] setting
a、 Selective and programmable EDID setting is added into GeoBox. The purpose are as follows:
GeoBox can support non-VESA standard input signal timing—from 1024*720 up to 4k/2k. In
order to get the best video performance, user needs to select optimized input signal resolution.
Different PC display cards have different setting and behavier. Many users may not be able to do
the right settings
High end media player or server can support big range of outputs. If GeoBox no EDID selection
function, the output resolution shall be set manually.
Different display modes may show different final image aspect ratio. User can ultilize different
EDID setting to change input signal timing and get different output aspect ratio for PC desktoop.
b、 Procedures to set customized output resolution in PC:
PC and other signal sources may not follow the EDID settings from G-eoBox and show
different result. If it happens, please set output resolution manually.
In PC output resolution settings, please select GeoBox as display device. Then user can
choose the maximum resolution set by EDID in GeoBox.
Please select Reduced Blanking timing in high resolution output to reduce the output clock for
easy high speed data connection.
Activate EDID setting menu:
[Options] [Setting] [EDID]
Use IR remote controller to select desired
EDID.
After select EDID, signal source will
auto-change the output timing setting.
Press [INFO] key to check if the input and
output timing are set correctly.
G-602
49
After user creates custom output resolution in PC, use may need to go back to Resolution
Selection Window in PC to select the desired output timing.
Note:
a. Some signal source devices only detect EDID at booth up stage. Please open GeoBox 2-3 seconds
before open signal source so that signal source can detect the EDID setting in GeoBox during booth
up stage and send out the right timing.
b. After finish FW update, please select a different EDID resolution in EDID selection menu, then go
back to required EDID resolution. This action will update EDID timing list from new FW into GeoBox.
c. User can also set non-VESA standard output timings from PC, GeoBox can accept this kind of
output timing under the conditions that the maximum clock rate shall be under 330MHz and the
resolution shall not exceed 3840x2400.
15 System bandwidth and system crash
Due to hardware bandwidth limitation, it is possible to see some abnormal image during some settings. It is
due to processing bandwidth limitation. It may happen in below conditions:
1. High resolution input source like 3840x2160 with different video wall ZOOM and Overlap settings.
2. When implement extreme geometry alignment.
3. Executing PIP/POP with 4k/2k input signal with big geometry range.
4. Edge blending with projector at portrait position.
5. When implement active 3D 120Hz input/output.
6. We suggest to select the image vertical resolution same as projector. If user uses 1280x800
projectors, then 3840x800 or 3840x1080 signal resolution should be selected.
7. Once it happens, please reset the system and select different settings. Once it normally displays, no
side effect will happen again.
Besides selectable EDID list, user can
[Customize] EDID manually.
The range for Customization:
H: 1024-3840
V: 720-2400
Based on VESA standard
Horizontal resolution is in a step of 8
pixels and vertical resolution is in 2
pixels.
After creating the EDID, PC or laptop
may still can’t output required timings
due to hardware limitation or driver
issue. In this case, user needs to
manually select output resolution.

16 Example for edge blending procedures
(Please see detailed edge blending procedures in [Quick User Guide], available in website.)
a、 System connection: No limitation in type of signal source
b、 Make edge blending plan: please contact us for assistance
This plan will provide all necessary information for projector selection and installation.
c、 Mark image location and install projector
To mark image location for each projector will simplify the installation.
d、 To do geometry alignment
Each projector should have the same image size with overlap grid complete stacking together.
Based on these data, user can make a layout plan and decide the
installation dimensions and locations.
G-602
51
e、 Video wall setting8
Split source image and assign to each projector, then adjust overlap pixels based on the overlap
region.
f、 Edge Blend settings
Edge blending to smooth image color. To let adjacent images RED & GREEN lines merged together.
g、 Image quality fine-tune
To adjust gamma value and select correct projector display mode.
17 Screen Selection
a. Gain value less than 1.5 will be recommended for Edge Blending application. Higher gain value
will be more sensitive to color difference among projectors. In short throw projector edge blending,
viewer may see different edge blending result while viewing at different angles.
b. Motorized screen position may be shifted from time to time. It will affect the image stacking in edge
blending area and may cause blurred image. Fixed screen is recommended.
c. If ultra-short throw ratio projector is used, the screen gain value should be under 1.00. The flatness
of the screen will be also more important in this kind of projector.
18 Projector Selection and settings
a. The projectors for the edge blending should be the same model and the same production lot. If
they are not the same models, it may create some difficulty and performance issue.
b. Usually, higher contrast ratio in the projector will have better black level performance. The
projector with contrast ratio more than 3000:1 is recommended for edge blending. In a dark
environment, video projector with 10,000:1 contrast ration or higher will be better. This contrast
ratio should be native contrast ratio but not dynamic contrast ratio.
c. If possible, please shut down Brilliant color and Dynamic auto color adjustments. They may affect
edge blending result.
d. All the projectors shall have the same setting—including optical zoom ratio, color temperature,
color characteristics, lamp setting, display mode...etc.
e. Please select a display mode with the best performance. Usually, Standard or Native display mode
will provide easier color fine tune.
f. Please select gamma 2.2 for best edge blending quality.
g. The mechanical stability in optical system is important. It should be rigid with less thermal drift.
h. A projector with big ZOOM and lens shift will be more convenient for the installation.
i. Throw ratio will affect installation distance, Please select right one based on the installation space.
j. If ultra-short throw projector is used in curved screen, it will cause big image position shift and may
also cause focus issue. Carpentry screen and curved screen are not recommended.
