a、If the video wall has more than 4 LCD, multiple units of G-403 is required.
b、If the signal source is 1920x1080, no matter how many LCD inside video wall system, user can connect
the signal source to all G-403 through daisy chain connection via loop out port.
c、User needs to capture Top Left and Top Right coordinates in each LCD and input to corresponding
G-403, then it can build an entire video wall.
d、If the signal source is more than 4k/2k and user wants to get higher output resolution, user needs to
crop the image into several FHD sections and assign each section to corresponding G-403. The
cropping line for adjacent G403 can be at different locations. User can use Video Wall [Zoom], [Pan]
and [Overlap] function to crop, assign and align the final position among all G-403. All of the operations
can be done through Remote Controller and OSD but not in GAlign PC tool.

9 Portrait display mode
If the display is at portrait position, user can apply the same procedures as above to build the video wall.
User can also rotate the video wall at 90/270 degrees and collect the coordinates to build the system to get
higher output resolution and better video quality. After installation, user needs to apply 90/270 degrees
rotated content or to apply GeoBox 90/270 rotation function to get correct display.

G-403-3
14
9.1 Comparison between landscape/rotated content in portrait display
If required video wall is at portrait position as below (3x landscape LCD stacked at vertical position), the
video wall aspect ratio is around 16: (9x3)=16:27 (H:V). User has two choices:
a、User can apply the content with 720*1080 (16:27) resolution to get non-distortion image with total
video wall vertical resolution at 1080.
b、User can also apply a content with 1823x1080 (27:16) resolution and rotate the content at 90/270
degrees in PC or media player. The final resolution will be 1823x1080:1080x720=2.53x higher.
c、G-403 can handle both cases no matter the content has been rotated or not. However, user will get
higher resolution image if the content can be pre-rotated.
10 Image position fine-tune
a、Please apply video wall test pattern and check if further position adjustment is required or not. Test
pattern can be downloaded from our website (www.vnstw.com).
b、For simple video wall array, user can use remote controller [F1], Top Left] and [Top Right] hotkeys to
do fine tune without seeing OSD. [F1] key will provide [Shift] function to do image position

G-403-3
15
adjustment for each LCD in H&V directions without change the image rotation angle and size.
Please figure out the coordinates in the Top Left and Top Right corners and adjust the coordinates if
necessary.
c、For large video wall or irregular array, it will be more convenient and easier to use GAlign PC tool for
image position fine-tune. Please use enable [Real Time] mode and use [Shift Mode] or [Top Left] &
[Top Right] command to change image position & size.
d、Starting fine-tune from video wall center position, then extend to outside area. User need to apply
test pattern for easy fine-tune.
e、After finishing adjustment in PC Tool, please disable [Real Time] mode and save the final result into
[Index #] and GeoBox through [Write] command.
f、In multiple G-403 application, user can adjust LCD position in each G-403 separately, then use
[Video Wall] setting to combine them together. User can also combine all G-403 image together first,
then adjust each LCD image position.
g、Please save the final result in [Profile].
11 How to determine source signal resolution for a video wall
a、The feeling of the video image quality is related to many factors. The final display video pixel pitch and
watching distance are two major factors in video wall.
b、If user applies FHD signal source for a 5x5 video wall with 55” LCD, the source image pixel pitch is
1220mmx5/1920=3.1mm. If the watching distance is more than 3m, the video quality is acceptable.
Above this dimension, user needs to apply 4k/2k signal source. If watching distance can be 5m, user
can apply one FHD signal to a video wall up to 8x8 matrix with 55”LCD (5mm x1920 =9.6m in width).
c、If 4k/2k signal source is applied, all the devices between signal source and LCD display should also
be able to processing or deliver the signal more than 4k/2 to achieve high quality video image.
d、Multiple G-403 can process and deliver 4k/2k image with highest video quality.
12 How to show full operation menu in signal source
a、After the complete setup, user may be difficult to see the menu or PC Desktop for operation in
irregular video wall. User has below choices to see full screen image in LCD for further operation:
To connect G-403 Loop out port with one monitor to see full screen image.
Click Remote control Index key [OTH] to activate default setting to see full image in each LCD.
To turn on front panel [Main Input] Dip SW and turn off all [Display Mode] Dip SW, then Power on
G-403 again to enable full image in each LCD.
After finish necessary operation, user needs to return to required settings to get desired display.
b、Please set signal source with “Auto-Run” so that end user can power on the signal source and the
system will run automatically.
13 Image looping playback and LCD Burn-in Mark protection
a、User can create up to 10 display modes (Indexes) and execute looping playback with selectable
time interval and display modes.

G-403-3
16
b、The display mode can show different display settings in each LCD, including different size, image
location & rotation angle. Different aspect ratio and display position in entire video wall can be put
into different display modes as well.
c、One of the applications is that user can display a product at different rotation angle or zoom in/out
the product to see different feelings. User can also display a series of products on the screen and
pop up each product at different time interval.
d、If user applies two same display modes in looping playback, the switching time interval will be also
double.
e、By the same concept, user can slightly shift the image at some time interval to prevent burn-in mark
in LCD. This is important for a still image display on the LCD.
13.1 Example for looping playback settings:
a、Please check YouTube Video at: https://youtu.be/4Gc0KcuX27g
b、Description: 4 LCD installed at different directions.
c、Looping Range: 5 (5 indexes), Looping Time: 1 second

Set [Loop Time]=1 (for 1 seconds interval)
e、Save to Profile 1 & 5 (Profile 5 as Backup)
f、Power Off/On again to confirm the final settings.
14 How to change display aspect ratio and image position
a、User can change entire video wall image (4 LCD) aspect ratio from 25% to 200% at both horizontal
and vertical directions through [Warp Ratio] & [Warp Position] commands in GAlign PC tool or [Ratio]
& [Position] hotkeys in IR remote controller.
b、This function can solve image aspect ratio issue due to different aspect ratio between signal source
and the video wall. User can easily select one optimized aspect ratio as needed.
c、The above aspect Ratio and image Position changes can be saved into different display modes for
looping playback so that viewer will see more impressive video wall.
15 EDID setting
