8.3 [Overlap] – Position Alignment
[Overlap] adjustment changes the cropping area of the source image so that image position in each
monitor will be shifted. It can compensate Bezel Size of the monitor and correct misalignment in monitor
installation. If overlap value is decreased, each monitor will crop less image area and cause [zoom in]
(enlarged) effect. If overlap value is increased, each monitor will crop more image area and cause [zoom
out] (shrunk) effect. User can also use this function to correct position mis-alignment in installation, shift
image location for irregular video wall and set overlap area for projector edge blending application.
For No. monitor: For No.
Horizontal Pan = 3 Horizontal Pan = 3
Vertical Pan = 1 Vertical Pan = 2
monitor:
Maximum [Overlap] adjustment value is 900 pixels in all directions.
User can see the image and select Edge to adjust [Overlap] value for Bezel compensation and to
adjust image mis-alignment due to monitor installation issue.
User can use [Overlap] function to stretch the image outside video wall (some image will be
missing) or draw image inside video wall with Black blanking area at the edge. This function can
adjust the aspect ratio of the content to meet required aspect ratio of the video wall. Please see
more details in [Flexible Aspect Ratio Adjustment] section.
Asymmetric video wall can be achieved through overlap adjustment even with different size of
monitor and bezel dimension.
8.4 Bezel Compensation
Through [Overlap] menu, user can adjust image cropping area and adjust image position.
User can apply test pattern and reduce [Overlap] value to enlarge the image to the bezel center
line between two monitors to achieve bezel compensation.
User can also calculate the pixels number for bezel compensation based on the video wall
dimension and bezel size. If the video wall active display area is 360cm in width and the input
source is 3840, then the pixel number for each centimeter is 3840/360=10.67 pixel/cm. If the bezel
size is 12mm in one edge, then user can decrease Overlap value 10.67*1.2=12.8 (13) pixels to do
bezel compensation for that edge (to enlarge the image 13 pixels at that edge).

G406 User Guide Document: G406-3
------------------------------------------------------------------------------------------------------------------------------------------------
9.1 Introduction
Asymmetric video wall can be created by rotating monitor installation direction or position. User can
crop different area image for each monitor, rotate image direction and adjust image position
through G406 to achieve it.
Note: Image flip and rotation are only available when input resolution is under 4k/2k @30Hz.
User can use monitors with different dimensions, bezel size and resolution as display devices. No
data base for monitor is required and it allows user to have some deviation in installation position.
All of these factors can be corrected by GeoBox video wall settings.
G406 can only rotate the image at 90/180/270 degrees. The monitors need to be installed at
landscape or portrait position. If users want to install monitor at other rotation angle, G-403 model
should be used.

Aspect Ratio and image distortion
- If the source content aspect ratio is not 1:1 in this Video Wall setting, the final image will have
some distortion.
- User can adjust source resolution and content aspect ratio to fix this issue
Set display EDID with 2160*2160 with same ratio as the aspect ratio of Video Wall.
Use PC as signal source with 2160*2160 output resolution and use content with 1:1
aspect ratio. Customized output resolution setting in PC may be required.
- If source resolution and content don’t match the above conditions, user can adjust the display
aspect ratio in video wall settings to reduce image distortion but it may have below issues:
With some blanking area at some borders.
Display with full screen but some image will be stretched outside display borders and
can’t be seen.
- If user wants to change video wall display image aspect ratio, user needs to adjust Position
Reference Line first. In this example, if user wants to stretch horizontal image, user needs to

adjust TV3 and TV2 horizontal scaling factor first (grid size), then to align TV1 and TV4 to
match TV3 and TV2 with test pattern.
9.4 Other Big Scale Asymmetric Video Wall
If there is a video wall required large number of controllers to achieve it, users can have two options:
A. To adjust image directly through remote control and test pattern
a. To apply test pattern and familiar with test pattern and related positions.
b. To execute [Zoom], [Pan] and image rotation settings.
c. After individual LCD image location is determined, you can use remote control directly to
adjust the image location according to the test pattern.
d. The general adjustment order is from the video wall center and outer edges first. If you can
adjust the size of the grid in horizontal and vertical directions in some monitors as reference
baselines, then all other monitors can be adjusted according to these baselines.
B. The second way is to do position measurement for each monitor according to design drawing or
picture, and use remote control and test patterns to input adjusting parameters directly.
a. First step is to measure H&V active display area dimensions of the complete video wall setup,
for example, 400cm X 180cm.
b. Determine the signal source resolution: For example, 3840*2160
c. Calculate the desired display pixel per each centimeter: horizontal: 3840/400=9.6 pixel/cm,
vertical: 2160/180= 12 pixels/cm
d. Based on the monitor layout, to execute [Zoom], [Pan] and rotate the image if necessary.
e. When the image position of individual LCD is determined, user needs to measure the
distance between corner position of active display area in each monitor and the image
location determined by the [Zoom] and [Pan].
f. Using these distances and pixel densities per centimeter, you can calculate the approximate
horizontal and vertical position adjustment pixels.
g. Use the remote control to adjust the image position directly according to the calculated value
and the test pattern.
Example of an irregular TV wall setting with 8 monitors
a. The actual physical pixel on the upper edge display is: 6000. If the 3840*2160 signal
source is used, the signal source pixel on the upper edge is 3840. So the actual ratio is
6000/3840=1.5625. The vertical actual ratio of the 3000/2160=1.3889
b. When user executes Video Wall [Overlap] setting, it adjusts cropping area of the signal
source and changes the image position accordingly.

TV1 settings:
a. [Zoom]: H=6, V=2, [Pan]: H=1, V=1, [Image orientation]: 90 degrees or 270 degrees.
b. When TV1 horizontal zoom is 6, the actual hardware pixel in each horizontal section is
6000/6=1000. TV1 's vertical zoom is v=2, the actual hardware pixel in each vertical section is
3000/2=1500
c. The horizontal edge of TV1 should be assigned with 1080 pixels, but [Zoom] setting only assigns
1000 pixels to TV1. It is necessary to use the [overlap] adjustment function to add 80 pixels to the
TV1. After converting to the signal source pixel, the TV1 [Overlap][Right Edge] adjustment
value should be: 80/1.5625=51.2 Pixel (+51).
d. The vertical edge should be assigned with 1920 pixels, but [Zoom] setting assigns 3000/2=1500
pixels to TV1. It is necessary to use [overlap] adjustment function to add 1920-1500=420 pixel to
TV1. After converting to signal source pixel, TV2 [Overlap][Bottom Edge] overlap adjustment
value is: 420/ 1.3889=302.4 Pixel (+302).
TV2 settings:
a. [Zoom]: H=4, V=2, [Pan]: H=2, V=1
b. When the TV2 horizontal zoom is 4, the actual hardware pixel in each horizontal section is
6000/4=1500. TV2 's vertical zoom is V=2, the actual hardware pixel in each vertical section is
3000/2=1500
c. The horizontal edge of TV2 should be assigned with 1920 pixels, but [Zoom] setting only assigns
1500 pixels to TV2. It is necessary to use the [overlap] adjustment function to add 420 pixels to
the TV2. After converting to the signal source pixel, the TV2 [Overlap][Right Edge] adjustment
value should be: 420/1.5625=268.2 Pixel (+268).
d. The vertical edge should be assigned with 1080 pixels, but [Zoom] setting only assigns
3000/2=1500 pixels to TV2. It is necessary to use [overlap] adjustment function to decrease
1500-1080=420 pixel to TV2. After converting to signal source pixel, TV2 [Overlap][Bottom
Edge] overlap adjustment value is: 420/ 1.3889=302.4 Pixel (-302).

a. Below is [Overlap] adjusting value for each monitor without taking bezel compensation into
account.
b. If bezel compensation is required, user needs to enlarge the image in each monitor to the center
line between two monitors (some image will disappear). Assume the bezel size is 10mm and the
monitor is 42”(active display area is 930*523mm)。
Horizontal pixel density: 3840/ (930*2+523*2+10*6)= 1.295 /mm

Two G406 can build
TV wall as Left.
More irregular video wall example:
Method 1: Calculate [Overlap] adjustment pixels based on design drawing or installation
picture.
a. Users can draw an outer frame in the display area using a photo or project drawing.
b. Measure the vertical and horizontal dimensions of the outer frame, and divide the resolution of
the signal source by the horizontal and vertical outer frame dimensions to get the H&V pixel
density per centimeter.
c. Measure the distance of the display area in each monitor in both horizontal and vertical positions.
d. By using the position distance and pixel density, user can calculate the pixels for position
adjustment.
e. When user set [Zoom] and [Pan] for each monitor, user can also understand the TV wall cutting
position.
f. Based on the above information, user can calculate [Overlap] adjustment value. After finishing
[Overlap] adjustment, user can apply test pattern and execute position fine-tune.
Method 2: Apply test pattern and execute image position adjustment directly
a. Users can also align the image directly using the test pattern.
b. The image center point is estimated and marked.
c. Take the middle monitor TV1 as an example:
The center point of the TV wall is in the upper position of TV1.
Rotate the image, set [Zoom] as H=5 (about 1/5 in the horizontal direction), V=2
(approximately 1/2 in the vertical position), [Pan]: H=3 (in the 3rd position while H= 5), V=2
(vertical 2nd position).
Apply test pattern, select the TV1 connection channel.
22
G406 User Guide Document: G406-3
------------------------------------------------------------------------------------------------------------------------------------------------
Use [Overlap] menu to select the top/bottom edge to adjust the vertical position of the test
pattern and let the center point of test patter to match TV wall center point.
Then adjust the left and right edge [Overlap] value so that the horizontal grid and the vertical
grid have similar size.
Next step is to set TV2/TV3 [Zoom] and [Pan]: set [Zoom]: H=3 (about 1/3 of the horizontal
direction), V=4 (approximately 1/4 of the vertical position). TV2 [Pan]: H=1 (1st position of
horizontal direction), V=3 (3rd position of vertical direction); TV3 [Pan]: H=3 (the 3rd position of
horizontal direction), V=3 (3rd position of vertical direction), and uses [Overlap] function to let
the test pattern align together. If there are some images missing or black borders at both
sides, user can shrink/enlarge the TV1/TV2/TV3 grid size, so that the grid can cover full frame
of TV wall with the similar horizontal grid size in all TV.
The other three upper monitors can be set in a similar manner so that the test pattern can be
aligned together and the grid size can be consistent with the other three monitors in both
vertical and horizontal directions.
If necessary, image fine-tune is required to complete the whole setup.
10 Flexible Aspect Ratio Adjustment
User can change the aspect ratio of the image with black borders or to stretch the image in specific direction
to compensate the aspect ratio difference between video wall and the content. The Maximum adjustment
range is 900 pixels in each edge.
23
G406 User Guide Document: G406-3
pixels in each edge.
------------------------------------------------------------------------------------------------------------------------------------------------
Activate [Overlap] under [Video Wall] menu
1. User can select the channel and the
edge required for edge shift, then adjust
Overlap value to see aspect ratio
change.
2. The image position shift range is +_900
1. If the image is at portrait position, this function is only available under input signal up to 4k/2k @30Hz.
2. If Video Wall [Zoom] is set to H=2 & V=2 or above, user can apply 4k/2k @60Hz input signal. The
adjustment range (900 pixels) is calculated based on signal source resolution.
3. When user adjusts Overlap value in one monitor, it will also change the scaling factor. User needs to
adjust the Overlap value in other monitors to let all monitors has the same scaling factor.
4. The adjustment range of 900 pixels is calculated according to the signal source resolution. If the signal
source is 4k/2k and the adjustment value is 900 pixels, when switching to 1080p input signal, the
adjustment value will be converted to 450 pixels automatically to maintain the same image position. If the
input signal source is 1080p and the adjustment value is 900 pixels, when switching to the 4k/2k input
signal, the adjustment value will be maintained at 900 pixels, and the image position changes to the
position of 900 pixels (about half the distance) of the 4k/2k signal.
11 Save System Settings through OSD Menu
After finishing system settings, user can save the setting by OSD menu through [Menu]
[Options] [Setting] [Profile] [Save] [Index 1-5]. [Save] Profile will take effect for two
channels in the same display group. User needs to Save CH1/CH2 & CH3/CH4 separately for one
G-406.
User can recall the setting (Load) through IR remote controller or [Profile] hotkey on Front Panel.
Five different display settings can be saved to [Profile]. The data stored in Profile include EDID
setting, input source, output resolution, color settings and all user customized settings.

15 Helpful tips for video wall settings
15.1 Image distortion and aspect ratio issues
If the content aspect ratio is different from video wall, it will cause image distortion. User can adjust
aspect ratio through [Overlap] settings. However, you will have two choices:
Full screen display but some content will be drawn to outside border and missing.
Draw the image into video wall and keep some blanking border at some edge.
15.2 If the signal is from PC, user can set customized EDID in GeoBox to let PC output expected output
resolution. Some PC may not follow GeoBox EDID resolution setting and require customized output
setting from display card.
25
G406 User Guide Document: G406-3
------------------------------------------------------------------------------------------------------------------------------------------------
15.3 User can set different video wall settings in each channel and crop different area for the display. In
combination with ZOOM, PAN and OVERLAP settings, user can crop any location of the image for each
LCD, no matter it is in landscape or portrait position.
15.4 Pay attention to image rotation limitations in input signal resolution. G406 doesn’t have image rotation
function when the input is 4k/60 Hz.
15.5 G406 can support interlaced signal source (i.e. 1080i). However, if user rotates or flips the image, there
will be no 3D motion adaptive de-interlaced function. User may see some small flick image while the
input is still image. We strongly recommend applying progressive signal for the best video quality.
15.6 Some media players will output maximum resolution when it is powered on each time but not follow the
EDID settings in sink device. It will cause abnormal display in the video wall if this video wall has image
rotation setting and the signal source resolution is more than 4k/60Hz because G406 can only support
image rotation under 4k/30Hz source signal.
16 Convenient Setting In Multiple Unit Application
16.1 Setup by Remote Controller
16.1.1 If multiple units are used, user can set different [Box ID] (#1 - #99) or IP address in each Box for
individual control. For IR control, the [Box ID] number range is #1 - #9.
16.1.2 User can control individual GeoBox through below method when all boxes or IR extender
receivers are installed together.
Press 851 number key on remote controller will lock all other G406 OSD menu except G406
with Box ID #1. User can see flashing LED on the Front Panel for the units with OSD locked.
Press 853 will only unlock ID # 3 G406 for further OSD operation and lock all the others.
Press 850 will unlock all G406 OSD Menu. Remote controller can control all boxes at the same
time.
16.2 Setup by Ethernet
User can connect all G406 in one Ethernet Router (WiFi Router or switch/hub) through LAN ports and
set different Static IP address for each Box, then use WebGui virtual keys or UWM PC tool to control
each G406 independently. Default IP address is 192.168.0.100. Web Server function is available.
Please contact us for more details.
16.2.1 WebGui
WebGui is embedded inside G406. Once user connects G406 with PC through Ethernet, user
can access WebGui and execute all operation similar to OSD menu through Virtual Keys and
OSD Menu. No PC or appropriate software tool is required.
The connection can go through Ethernet router LAN port, WiFi Router or Crossover Cab 5/6
cable. User can set each G406 with different static IP address in the same domain, then open
Google Chrome or Microsoft Explorer browser with IP address to access each unit of G406 for
independent operation. There is no limitation in the number of G406 that can be controller at the
same time.

Image 90/270 degrees image rotation is only available in input resolution under 4k/2k @30Hz (included).
While image is rotated or flipped, there will be no 3D motion adaptive de-interlaced function. We recommend
apply progressive source signal to get the best video quality.
19 Limitation in Audio Output
User can only select one audio output from each display group - Group A (CH1/CH2) and Group B
(CH3/CH4). In each Group, if both HDMI and DP input are selected, then only HDMI audio will be selected as
audio output.
20 Trouble Shooting
20.1 Front Panel LED lights
User should see Input/Output LED lights in each channel. If no light illuminated in specific channel,
please check Input/Output connecting cables, signal source & monitor in that channel.
If user sees continuous flashing in some channel LED, it means OSD may be locked. Please press
[Menu] key for 5 seconds, it will disable [OSD locked] function.
If [INFO] key LED is lighted, the OSD Menu is locked and can’t be used. Please use remote
controller and press [850] number keys to disable OSD Menu Lock.
20.2 Intermittent or Loss of Input Signal
Check the HDMI cable quality and make sure all cables are fitted correctly. 4k/60 signal requires
high speed certified cables.
31
G406 User Guide Document: G406-3
------------------------------------------------------------------------------------------------------------------------------------------------
Cable length: Connecting cable length should be short as possible. Replace a short cable to verify
the possible root cause.
HDCP compliant issues: If the input source or the monitors are not HDCP compliant, it is possible
to stop G406 from negotiating HDCP link and show intermittent, abnormal or no image.
Resolution issues: check if signal source and connecting cables can provide right signal requested
by G406.
DVI/HDMI signal compatibility: some display devices may only support HDMI or DVI video signal
and execute wrong signal format detecting. The default output is HDMI. User can change output
with DVI format through [Options] [Setting] [DVI] [On].
Usually, to swap with different cable, output channel, signal source and monitor can verify the root
cause for the failure.
When it is possible to have signal compatibility issue, user can add one HDMI splitter or switch in
the middle to change signal impedance. It may fix the issue.
20.3 Image rotation can’t be implemented
If the input signal is above 4k/2k @30Hz, image 90/270 degree rotation function will be disabled.
20.4 Video quality issues
Use the highest resolution and number of color bits (RGB 4:4:4) images allowed by G406 to be
used as a signal source whenever possible.
There are a number of lower-quality AV players, the specification and actual output are difference,
or because of the use of lower color sampling bits or poor image compression technology, resulting
in lower quality or image is not smooth (LAG).
If the use of H.264/H.265 compressed files, please select a player with hardware decoding to get
smooth video quality.
If the input signal is interlaced signal (interlaced-1080i), and the image is rotated or flipped, then
the channel will have no [3D Motion adaptive de-interlaced] processing function. If user applies
static image source, the output video will have a slight jitter phenomenon. The processing channel
quality will be reduced. Use a progressive signal source setting (1080p/2160p) whenever possible.
Please press [INFO] shortcut key to check the input/output signal settings.
20.5 System setting can’t be executed:
System control applied to complete system can only be executed through CH-1.
After FW update, please insert small pin into RESET hole on back panel for 5 seconds to reset the
system to default to eliminate unnecessary settings. It will not affect Profile Index storage data.
20.6 Synchronization issue in the outputs
The input refresh rate should be the same as output refresh rate so that the system can implement
Frame Lock to synchronize all the outputs. If the input source is 50Hz with 60Hz output, then it is
possible to see some lag among the displays.
The display devices may have different delay time under different settings. For examples, if the
system with high end video processing, such as noise reduction or ME/MC, it may increase few
frame delays. Please make sure all the display with the same settings.
