INTRODUCTION

The Avenview MLT-EDGEPRO-2X2 is a professional edge- blending 4K video wall processor. Equipped with

advanced edge blending, image warping, projection mapping, and passive 3D, the device enables the user to achieve a

flawless unified image.

Configure the device using one of the five user-friendly control options; front panel keypad, IR controller, PC software

via USB, WEB GUI via Ethernet or RS232 for 3rd party control systems. The user can easily perform independent color

adjustments, black level uplift and an advanced geometric alignment of up to 17x17 grids to get live on-screen

optimized results.

The device supports five (5) multi-format input ports with resolutions ranging up to 2560x1600/3840x1080@60Hz and

4K/UHD 3840x2160@30Hz. The integrated (2) HDMI output ports support a full 4:4:4 color subsampling scheme

ensuring a seamless multi-projector solution for any market sector.

The MLT-EDGEPRO-2X2 processor supports a motion adaptive de-interlace which helps avoid visual artifacts by

performing high video optimization. The device is also capable of converting the film frame rate directly to a video

frame rate through the 3:2/2:2 pull down feature. Our product can tailor to unique setups that do not comply with

standard VESA timing specifications.

Easily create larger, more impressive displays without sacrificing signal integrity through the embedded HDMI loop our

port, available for daisy chain connection to cascade with multiple MLT-EDGEPRO- 2x2 devices. Users can now avoid

complex and costly solutions by replacing high end projectors with lower spec devices lacking integrated land-shift,

warping and edge blending capabilities.

System Configuration

The Avenview MLT-EDGEPRO-2x2 can decode most 3D formats from all kinds of 3D video sources, including bluray
DVD, STB, Media player, Game console and more.

The 3D signals needs to be displayed through two projectors, each projector will display the decoded signal for both
the right/left eye.
Also have handy a set of polarized filters and polarized glasses. The glasses need to match the polarized filters in front
of the projectors so that the right eye can and the left eye can only view the scene for each eye.
To preserve the polarization of the light for 3D display, please use a silver 3D screen. Also recommended the optic

spectrum method from Dolby, Infitec or Omega Optical to allow 3D display on normal 2D screen.

System installation and setup

1. MLT-EDGEPRO-2x2 should not be close or at the side of the projector where the hot air ventilation is blowing.

2.

Place the two projectors side by side or top/bottom. Placing the projectors in close proximity to each other will reduce
gap of the geometry adjustment also the loss of the image resolution and brightness.

Please make sure the ventilation air flow will not affect the other projectors, placing an isolated board between two

projectors can be added if necessary.

3. Set higher output resolutions such as from 3D signal source and connect to any input.
Unit will decode and distribute the signals for two projectors.

4.The two projectors must be connected to the MLT-EDGEPRO-2x2 device to display an image for each right and left eye.

5. Setup the polarized filter and glasses so that right/left eye can only see the scene for one eye.

6. Use geometry alignment function to align the images from two projectors completely matching together.

Please place the polarized filters in front of the projector before using the [4 Corner] adjustment because the
polarized filter will affect the direction of light from the projectors. A good alignment will give double brightness for
the projection in 2D display. For best results with the brightness the two projectors should be placed as close as
possible and the screen must be flat or smooth curve.

NOTE: Some deviation in alignment is allowed for 3D display but will affect the performance in 2D display.

Procedure For Active 3D Setting

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 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 also 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.

The major functions of the MLT-EDGEPRO-2X2 in active 3D applications are:
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. Unit can also convert 1080p 120Hz input into 1080p 60Hz output for passive 3D or 2D display.

1. To select the output resolution in the unit to XGA (for XGA projector) or 720P (for projector native
resolution larger than 720P) through front panel or remote control hotkeys.

2. To set 3D output format at [XGA 120Hz output] or [720P 120Hz output] under 3D Properties menu.

3. If user selects other output resolution except XGA or 720P, [3D Ready] menu will be grayed out and
user can’t select 120Hz output.

4. Projector needs to have 3D Ready DLPLink or Nvidia 3D Vision function. This 3D function needs to be
open while playing active 3D.

5. 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].

Under [Anyplace] menu, the user can find the (5) five main features of MLT-EDGEPRO-2X2 such as geometry
alignment, edge blending and warping.

The geometry alignment functions found in [Anyplace] is the same as tier one projector brands. It provides
professional performance in single & multiple projector applications.

• [2x2 Corner] alignment can’t co-exist with [3x3 Curved] or [5x3 curved] alignment.

When you apply [3x3 Curved] or [5x3 curved] function, original [2x2 Corner] alignment will be reset.

User needs to execute geometry alignment from the beginning.

• [3x3 Curved] and [5x3 curved] can co-exist. It means if you execute [3x3 curved] alignment first,
then go to [5x3 curved] alignment for further geometry alignment, [3x3 curved] alignment will not

be rest and user can continuously executing [5x3 curved] alignment.

• We suggest to start geometry alignment from [3x3 curved] alignment unless quick corner

alignment is required and not necessary to have precise geometry alignment.

• Geometry adjustment range in MLT-EDGEPRO-2X2 is based on percentage of the output resolution.

Higher output resolution the more adjustment pixel range.

• [Edge Blend] provides all the functions for seamless high performance edge blended image.

[2x2 Corner] - Correction

• [2x2 Corner] alignment is to adjust corner position of the image. When the screen is flat, this function

will quickly align image to the desired location. If the screen is not flat or has some distortion in the
screen, user needs to use [3x3 Curved] or [5x3 curved] for image geometry alignment.

• [2x2 Corner] alignment can correct image keystone at vertical and horizontal position.

• It can also adjust image height and width to change the aspect ratio of output image.

This function can’t co-exist with other geometry alignment function. If user applies [3x3 Curved] or
[5x3 Curved] alignment, then go back to [2x2 Corner] menu, the previous geometry alignment will be
reset to default. User can go back to [3x3 Curved] or [5x3 Curved] menu again, it will recall the setting
back to the screen. It means [2x2 Corner] alignment is independent adjustment and can’t combine
with [3x3 Curved] or [5x3 Curved] alignment.

• Activate [2x2 Corner] Menu by Front Panel keypad or Remote Controller.

• [4 Corner] hotkey is on the remote controller for quick access to this menu.

• [2x2 Corner] has the same

function as keystone correction.
It can do keystone correction in
both horizontal and vertical
directions.

• When the corner has been
selected for adjustment, user will
see a flashing white block on the
image to let user understand
which corner is under
adjustment.

[3x3 Curved] - Geometry Alignment

• [2x2 Corner] alignment can’t co-exist with [3x3 Curved] or [5x3 curved] alignment. It means when you apply [3x3
Curved] or [5x3 curved] function, original [2x2 Corner] alignment will be reset. The process has to be restarted

from the beginning.

• [3x3 Curved] and [5x3 curved] can co-exist. If you execute [3x3 curved] alignment first, then go to [5x3 curved]
alignment for further geometry alignment, [3x3 curved] alignment will not be rest and user can continuously

executing [5x3 curved] alignment.

• After executing [5x3 Curved] alignment, user can go back to [3x3 Curved] menu to do further 4 corner position
fine-tune. It will not reset [5x3 Curved] alignment result

• We suggest to start geometry alignment from [3x3 curved] alignment unless quick 4 corner alignment is required

and no need to have precise geometry alignment.

• There is [Warp] hotkey on remote controller for quick access for [Anyplace] menu.

[Shift] - Image 4 Corner Position Alignment

• [Shift] function is similar to [4 Corner]
geometry alignment.

• The adjustment points include 4 corners
of the image.

• The image change is based on straight
line between two corner points.

[Corner] - Corner Curve Adjustment

• [Corner] function is to adjust the position of the image
corners but the center points of each edge will

maintain at the same location. The function performs a
smooth curved line and not straight line.

• Left photo to show the image had been changed with
[Corner]curve adjustment.

[Edge] - Edge Curve Adjustment

based on a smooth line between two corner points of the edge.

• [Edge] function is to adjust the position of the image edge (center point) and the corner points together.

The image change is based on a smooth curved line but not straight line.

• Below is to show the three edges positions had been adjusted (next page).

[5x3 Curved] - Geometry Adjustment

[5x3 Curved] adjustment is more precise geometry alignment. When executing curved screen edge
blending, This function should be applied to align the image grids between two adjacent projectors to
match together. Without good alignment, the image in overlapped area will have blurred image.

• Note: the projector is designed with the same display grid size when the screen is flat. If the screen
is not flat, due to different throw distance, the image grid size will become different gradually. The
grid size dimension change between two adjacent projectors will be in different directions. This will
cause the grids in overlapped area not able to overlap perfectly and required [5x3 Curved] alignment.

• 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.

Note:

- [5x3 Curved] will cut the horizontal image into 4 sections and the image in each section can be independently adjusted.

In terms of different output resolutions, there will be different pixel number: XGA: 1024/4=256 (8 grids), WXGA:
1280/4=320 (10 grids), 1080p: 1920/4=480 (15 grids). If the overlapped area between two adjacent projectors has the
same pixel number as above, then the geometry alignment will have less flexibility.

- When doing edge blending plan, we suggest having some deviation with the above number to get more flexibility to do
overlap alignment.

- We suggest the overlap pixels can be +_1-4 grids (32-128 pixels). Here is the recommended overlap grids for curved
edge blending in different output resolutions:

3.8

[5x3 Curved] - Geometry Adjustment (Cont'd)

XGA: 6, 7, 9, 10, 11, 12 (no 8 grids);
WXGA: 7, 8, 9, 11, 12, 13, 14 (no 10 grids);
1080p: 9, 10, 11, 12, 13, 17, 18, 19, 20 (no 15 grids).
Please calculate the pixel number based on 1 grid=32 pixels.

- Please ensure the grid between the two adjacent projectors are aligned together, this will esure great
results on the final output. Horizontal lines in the grid alignment should be 100% match together.

The vertical lines are allowed to be separated. However these vertical lines should keep the same gaps
between two adjacent projectors.
User can adjust Video Wall [Overlap] value to compensate the gap distance and get crisp image.

[Edge Blend]

• To merge the images from multiple projectors to become one seamless image.

•

Ensure the scaling factor between two adjacent images shall be the same. Otherwise, the image will
be blurred. The image size should be related to the input resolution.

• Geometry alignment before edge blending is required:

- To let the image has the same grid size (same scaling factor in both horizontal and vertical directions)

-To let the images overlap together in horizontal lines

• 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.

- [Shift]: shift the location in edge blend area. In some case, it may help color fine-tune.

- [Corner]: to do precise [Offset] location alignment.

- [Color]: to do discrete color adjustment for individual projector.

[Edge Blend] - Selection and Settings

• [Edge] is to select the edge for edge blending and set the overlapped pixel number.

• The unit can perform edge blending on any edge.

Note: Max. edge blend pixels are 800. If over this number, please consider using image stack or change
aspect ratio in projector to shrink projection image.

[Edge Blend] - Selection and Settings (Cont'd)

• Color indicating lines will appear when settings
the edge blending pixels.

[Gamma] - Color Correction In Edge Blending Area

• 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 most common
issues are gray or color banding effect. These issues are more significant in pure color or white back ground display.

• [Gamma] to select the right gamma curve for edge blending area and [Offset] compensation area.

•

To adjust the color use the indicating lines to
match together (green to green, red to red).
There is no need to calculate the overlap pixels.

• To select the right edge for edge blending.

For three projector edge blending as example:

- Select [Left Edge] for RH projector

- Select [Right Edge] for LH projector

- Select [Right Edge] & [Left Edge]
for center projector.

• User needs to use [Color] menu to adjust the color difference among different projectors in advance.
Otherwise, it is possible that the banding effect in edge blending area still visible.

•

This function is not functional when [Edge] setting is not executed.

3.8

[Gamma] - Color Correction In Edge Blending Area (Cont'd)

• Two sub-menu in the [Gamma] tab

- [Transition]: To set edge blending area gamma
value. The image color change in edge blending
area is shown in real time to get the best quality.

- [Offset]: To set offset area gamma value to
avoid black level.
Change the [Offset] compensation area while
executing black level uplift.

Please note:

- Banding effect in edge blending area is related
to projector gamma curve. The projector

should have the same gamma setting and

[Display Mode].

- Please disable [Dynamic] color or
[Brilliant] color function in the projectors.
These function will change gamma curve based
on the content and affect final edge blending
image quality.

•

Left picture shows the banding effect in edge
blending area. This issue is related to many factors:

- Screen: gain value under 1.2 is recommended

- Projector: should have the same gamma and
Display Mode. Usually DLP projector will get
better result.

- Signal content: To avoid pure color or pure white
color content. Multi-media is the best

- Overlap range: too small overlap range will be
easier to see banding effect. 15%-25% with more
than 50 cm is recommended. (XGA: 6-10 grids,
FHD: 9-13 grids, each internal pattern grid size is
32 pixels)

[Gamma] - Color Correction In Edge Blending Area (Cont'd)

•When adjusting black level, [Offset] value will be
applied to complete color range and reduce
image quality. [Offset] gamma adjustment can
avoid this issue and let [Offset] adjustment only
affect black level but not normal image.

[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 non­overlapped 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.

•

Three sub-menu under [Offset]:

[Transition]: To set black level color Offset value
in edge blending area. It can’t be reduced
because default value is set at lowest level “0”.
No further adjustment can be done.

[Non-transition]: To set black level Offset value
in non-overlapped area. [Reset]: to reset [Offset]
value to “0”. Normally, user only adjusts [Offset]
compensation in [Non-Transition] area.

User can’t reduce [Transition] area black level.
The default value is set at
“0” already. No adjustment is required.

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 for Offset adjustment.

3.8

Geometry Correction and Edge Blending

39

[Corner] - Adjust [Offset] Compensation Position

•

After set [Offset] value in [Non-Transition] area, user can reduce the black level offset difference but user will also see
small light bar near edge blending border. Below is the reason:
The starting point of [Offset] for non-transition area compensation is based on Edge Blend borders after geometry
alignment. 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
for Offset adjustment.

•

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.

•

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 uplift in black level. Usually, except
near edge blending area, this kind of black level uplift is outside the display area (outside screen frame) and viewers will
not see it. However, when the projector is displayed on a screen without borders, Viewers may see this black level
uplift. It is outside active display area and can’t be corrected.

•[Corner] can adjust the positions for black level
[Offset] borders through change the end points
of the borders.

•

Geometry alignment on the borders of edge
blending area should be very accurate. Otherwise
[Offset] position in black level uplift will be
affected.

3.8

Geometry Correction and Edge Blending

[Shift] - Edge Blending Area Shift

•

[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.
Usually, user can try to adjust [Edge Blend] value
to check the final image quality.

•

The maximum range for the adjustment is 250
pixels.

[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 has
color difference, lamp brightness decay and lamp replacement issue. Through this [Color] adjustment, it will
improve the video quality in edge blending

•

[Corner] can adjust the positions for black
level [Offset] borders through change the end
points of the borders.

•

Under [Color] menu, user can adjust
separate RGB [Gain] and [Offset] value to
change the color and white balance.

•

[Gain] is to change the color slope and
[Offset] is to add value in all level of
brightness (0-225)

[Edge Blend] - Setting Procedures and Example

In edge blending procedures adjust the color from projectors first. Users can also use [Color] function to do
further adjustment. Please note that, any color adjustment will reduce the color dynamic range.

Edge Blend has the facility to enlarge the display screen area and change the aspect ratio with multiple projectors.
Three elements are required for edge blending:

1. To perform geometry alignment the projectors have the same size (warp function).

2. Video Wall function can split,crop and assign the proper image to each projector.

3. Edge blending allow projectors to be become a seamless image. Below is example of the procedures for three

projector edge blending. It is also possible to use Gwarp PC tool for sophisticated curve adjustment.

a. Excel Spread Sheet is available to for user to determine the projectors (resolution, quantity, lumens and throw
ratio) and information for system installation. Based on this information, user can make detailed project plan for
the complete system.

b. Placement of the Projectors:

- Select projectors with higher contrast ratio (above 3000:1 is recommended) and set projectors at reasonable
distance from the screen with 200-500 overlap pixels (or 40cm-100cm overlap width) between two projectors.

- Use removable tape as temporary marks to indicate the image edges for each projector (based on the data from
Excel Spread Sheet). Each projector should have the same display size. Otherwise the grid size in each projector
will be different and the blending image will become blurred.

- To project each projector a little over the display range for further geometry adjustment.
Please try to install the projector with less keystone image.

- To set parallel vertical overlap edges between 2 adjacent projectors and let the positions of the lines close to

pre-marked positions will get better video quality after Edge Blending image.

c. Projector setting:

- Reset projector to default setting.

- To disable “Auto Alignment” function if user wants to use VGA analog input signal to avoid image shift during

projector switching ON/OFF process.

- Disable Auto Keystone function and set new keystone value to let two vertical edges in adjacent image in parallel

vertically.

- Select a Display Mode with 2.2 gamma curve will reduce the color difference in overlap area for video display.

User needs to test with different Display Mode setting based on the application.

- Use projector internal color adjusting function to adjustment the color variation among projectors before

implement edge blending.

d. MLT-EDGEPRO-2X2 Setting:

[Edge Blend] - Setting Procedures and Example (Cont'd)

e. Geometry Adjustment:

- To execute [3x3 Curved] function:

1. Apply [Shift] function to adjust the corner positions in each projector to match preset marks

on the screen.

2. Apply [Edge] function to align image edges near the required positions.

3. Apply [Center] to let image center meet image horizontal center line.

- To execute [5x3 Curved] function for image position fine-tune.

1. To let image horizontal lines match together in all projectors.

2. To let each projector has the same image size.

3. To let grid patterns between two adjacent projectors overlapped together.

- If the system is for 3 projector edge blending, the center projector should be aligned first then to align the rest

two projectors to match center projector.

f. Video Wall setting (Image split and allocation):
After geometry adjustment, video wall setting is required. The functions of video wall are as follows:

- Split the image for different projectors (Zoom)

- Determine the location of the image for each projector. (Pan)

- To set proper overlap region in the edge between projectors (Overlap)

Example for 3x1 horizontal edge blending Video Wall setting

•

[Zoom] setting

- Select [Horizontal Zoom] [3] to split
the image for 3 projectors horizontal
edge blending.

- Select [Vertical Zoom] [1] because
only one projector in vertical position.

•

[Pan] setting
Select H=1, V=1 for LH projector
Select H=3, V=1 for RH projector.
Select H=2, V=1 for center projector

Example for 3x1 horizontal edge blending Video Wall setting (Cont'd)

•

[Overlap] setting:

- Please apply edge blend value based on
[Excel Spread Sheet]

- Select [Right Edge] for LH projector.

- Select [Left Edge] for RH projector.

- Select [Right Edge] & [Left Edge] for center
projector.

• Before Overlap adjustment: Double image will be showed in all overlap regions. User can apply [Overlap] value to
eliminate double image at the overlap region.

• An [Excel Spread Sheet] can be provided for the calculation in different setup. Below is the calculate result of Video
Wall [Overlap Value] for 2 projector edge blending. If no [Excel Spread Sheet] can be used, user can change [Overlap]
value in unit simultaneously and find a value with clear image in overlap area.

Notes:

- "Overlap" means the pixel # in the overlap region between projectors. User can check the grid pattern
to calculate overlap pixel. One grid is 32x32 pixels.

- For the value “59.5” in above example, user needs to set one projector with “59 and another one with “60”.

- After apply Overlap pixel, if user still finds blurred image in edge blending area, user can adjust Overlap value

up or down at the same time in adjacent projectors till clear image is found.

- The Overlap total value in each projector should be the same in order to keep the same image scaling factor.

[Edge Blend] - Setting Procedures and Example (Cont'd)

g. Edge Blending setting:

- Two images in overlap region merged gradually in different directions to become one seamless image.

The setting value is based on the actual overlap pixel number.

- Color fine tune under [Edge Blend] menu:

1. Select different [Gamma] values and check video performance.

2. Set right [Offset] value in None Transition area to compensate black level difference.

3. Apply [Corner].function to fine tune the location for black level [Offset] position

h. Image quality fine tuning:

- The final performance will be a combination of many factors—projector characteristics, projector setting, screen, ambient

light and units setting.

- Banding in overlap area under dark environment is caused by light leakage in the projector optic system. It is not possible to

be fixed by signal manipulation. The only way is to raise the black level in none transition area through [Offset] menu.

- MLT-EDGEPRO-2X2 blending default setting is for projector with 2.2 gamma settings. To select projector display mode

near 2.2 gamma setting will get the best result.

- The projector may retain light leakage near the border of the imager. It is not possible to be fixed.

- These factors affect final image quality;

i. MLT-EDGEPRO-2X2 Settings:

1. Edge Blending: Gamma, Shift, Offset, Gain.

2. Image Properties: To select Preset Mode to sRGB, Neutral or Bluish

3. Individual projector color adjustment before edge blending by [Color] function under [Edge Blend] menu.

ii. Projector & Screen Settings:

1. To adjust installation position of the projector and reduce keystone angle.

2. Increase Overlap region & reduce off axis angle. To change Display Mode, usually Standard, sRGB/

Neutral will get better result.

3. Try different color settings. If necessary to use 3D color adjustment in the projector.

4. Use a lower gain value screen.

Frame Lock and Smooth Switching Mode

[Frame Lock] will ensure the input and output frame rate synchronize together.

-With multiple units, the signal in each unit is synchronized without frame tear.

-However, when the input timing is changed or video source, the output signal will show black temporarily and the
projectors has to search for an input source also producing a "No Video Signal" shown on the screen.

-Solution- Use [Disable] frame lock to maintain continuous output in unit while input source or timing changes.

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 display
devices will re-synchronize the input signal again. When Frame Lock is [Disable], unit will shorten the time for mode
change. The system 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.

Box ID

•[Box ID] is the identification No of each unit.

- Devices ID No range from 1-99

- After set Box ID, the Edgepro unit can be
control individually via IR Remote controller,
RS232 & Ethernet

- User can use “85+ID” key on remote controller
to control each Edgepro unit.

EDID - Setting

Selective EDID setting is added into Edgepro unit. The purpose are as follows:
a. Edgepro unit can support a range of input signal timing—from SVGA up to 4k/2k. In order to get the
best video performance, user needs to select different input signal resolution.

b. Different PC display cards have different setting and behavier. Many users may not be able to do the
right settings

c. High end media player or server can support a range of outputs—from 720p to 4k/2k. If no EDID
selection function, only one default EDID can be selected by media player. The system may not show
the best video wall output quality.

d. 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 image aspect ratio.

• Activate EDID setting menu:
[Options]>[Setting]>[EDID]

• Use IR remote controller to select desired EDID.

• After select EDID, the PC or medial will

automatically change the output timing setting.

• Press [INFO] key to check if the input and
output timing are set correctly.

Note: In very rare cases, some PC may not detect
the right EDID from Edgepro unit and show
different result. If it happens, please open
resolution setting window and select desired
output resolution and set display aspect ratio
from PC.

Screen Selection

1. Gain value less than 1.5 will be recommended for Edge Blending application. Higher gain value will be more sensitive
to color difference among different projectors and also will have view angle issue.

2. Flatness in the screen is critical. If the screen is not smooth or flat enough, it will create difficulty in alignment. Then
the image in overlap area may become blurred due to alignment issues.

Projector Selection and Settings

1. The projectors for the edge blending had better to be the same model and the same

production lot. If they are not the same models, it may create some difficulty and

performance issue in the future.

2. Usually, higher contrast ratio in the projector will have better black level performance.

The projector with contrast ration more than 5000:1 is recommended for multiple projector

edge blending in most of the environment. In a dark environment, video projector with

10,000:1 contrast ration or higher is recommended. This contrast ratio should be native

contrast ratio but not dynamic contrast ratio.

3. Most of DLP projector will provide a function for 3D color adjustment to fine-tune R, G, B, Y, C, M six colors,

This will help color fine tune in multiple images from different projectors.

4. All the projectors shall have the same setting—including optical zoom ratio, color

temperature, color characteristics, lamp setting, display mode...etc

5. Most projectors have different display mode for different applications, such as

Presentation, Video, sRGB and User mode. Different display modes have different gamma

settings inside projector and affect the video quality in overlap region. User needs to try with

different display modes to find the best one for the application.

6. The mechanical stability in optical system will be important. It should be rigid enough.

Otherwise it will be easy misalignment among projectors sometime after installation.

A projector with big ZOOM ratio may be more convenient for the installation
