Introduction
G901 is multiple purpose video processor for video source switching, format conversion, scaling up and
down, image flip/rotation, video wall and PIP/POP functions. It supports various input sources and input
timings, including non-VESA standard input timings. It is an ideal front end processor for big display system
required 4k/60 input and output.
5 input ports (3x HDMI, 2x DP) and 1x HDMI outputs are designed in G901. Input supports up to
4096*2160 @60Hz, 4080*3840 @30Hz with 4:4:4 chroma sampling. Programmable Output supports up to
4096*2400 @60Hz. It is integrated with 10-bit high end processor, motion adaptive de-interlace, low angle
smooth algorithm, 3:2/2:2 pull-down cadence. Programmable EDID up to 4080 x3840 can optimize input
timing to get the best video result.
It can execute video adjustment in Brightness, Contrast, Hue, Saturation, Sharpness, color temperature
and discrete RGB gain adjustment. User can select deep color mode with true 10-bit color output to get
smooth gradient color.
Video wall function in G901 can crop specific location & resolution in source image for the output.
Overlap function allows user to change image position, aspect ratio and cropping area up to +_1800 pixels in
each edge. User can also adjust image position freely without changing image size. Multiple units of G901 can
build creative video wall with any LCD array at landscape and portrait directions.
PIP (picture in picture) and POP (side by side or top/bottom) are standard functions in G901. PIP
image size can be from 320*180 up to 1920x1200. It can be located at any location across entire display.
Main and PIP images are swappable. Both PIP and POP are functional while image is at 90/180/270 degrees
flip and rotation. Sub-image can be rotated and flipped independently. The cropping range and position in
both main and sub-image are adjustable. Maximum signal source can be displayed in one G901 is two.
User can use IR controller, USB, Web Gui and Ethernet for system operation and setup. It is designed
to work in 7/24 working environment and provides easy configuration, low entry barrier, cost effective, reliable
and flexible solution.

monitors display discrete content with true 4k quality. Each monitor can be at landscape or portrait
direction with PIP/POP image inside.
➢Signal source shall be connected before video wall settings. The setting parameters inside GeoBox
will automatically change according to different input resolution once the setting is finished. If no
signal source is connected during video wall setting, it will assume the input resolution is the same
as output resolution.
➢Press [V. Wall] hotkey on Remote Controller to activate [Video Wall] menu. WebGui and UWM PC
tool are available for Ethernet configuration. USB can also be used together with UWM tool.

10.3 [Overlap] –Bezel Compensation and Position Alignment
[Overlap] adjustment changes the cropping area of the 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 shift the whole image
location for irregular video wall and set overlap area for projector edge blending application.
➢Maximum [Overlap] adjustment value is +_1800 pixels in all directions.
➢User can see the image and select Edge to adjust [Overlap] value for Bezel compensation.
➢[Overlap] adjustment can also compensate the position mis-alignment while monitor
installation.
➢User can reduce [Overlap] value to stretch the image outside video wall (some image will be
missing) or draw image inside video wall with Black or Blue blanking area at the edge through
increase [Overlap] value. This function can adjust the aspect ratio of the content to match
required aspect ratio of the video wall. Please see more details in [Flexible Aspect Ratio
Adjustment] section.
11 Flexible Aspect Ratio Adjustment
User can use Video Wall [Overlap] function to
change the aspect ratio of the image with
black or Blue 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
1800 pixels in each edge.
