G904 is multi-function signal processor with 4k/60Hz input and output. Each box can display all-in-one
content across entire video wall as well as display discrete true 4k/60 content in each 4k monitor. Due to
special system design, it is also served as multi-viewer to display up to 5 contents in one monitor. Multiple
units can be cascaded to build big scale display system.
One G904 has four 4k/60 output channels. 3x HDMI 2.0 input ports (one port is shared with two
channels) and 1x HDMI 2.0 outputs are designed in each output channel. Input supports up to 4096*2400
@60Hz, 7680*2160 @30Hz with 4:4:4 chroma sampling. One HDMI 2.0 loop out port to provide daisy chain
connection with multiple units to become one big display system.
Programmable output supports up to 4096*2400 or 3120*3120 @60Hz. The range is from 800-4096
(with 16 pixels/step) in horizontal and 720-3840 (with 1 pixel/step) in vertical. The maximum resolution is
limited to H * V < 9,830,400. It supports various input sources and input timings, including non-VESA standard
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 enables optimized 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. It supports BT 2020 HDR 10 signal processing to get full 4k color gamut.
User can select deep color mode with true 10-bit color output to get smooth gradient color.
Video wall function in G904 can crop specific location & resolution in source image for each output.
Overlap function allows user to change image position, aspect ratio and cropping area up to +_1800 pixels in
each edge. User can adjust aspect ratio and image position freely. independent image 90/180/270 degrees
flip and rotation is also available in each channel. User 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) is standard functions in each output
channel. PIP image can be from 4k/60 source with image size from 320*180 up to 1920x1200. It can be
located at any location in one monitor. PIP/POP across entire video wall is possible through input the same
sub-image source to related channels. Main and PIP images are swappable. Both PIP and POP are functional
while main 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 display
windows can be displayed in one G904 is eight.
Through the combination of PIP/POP and 1/3:2/3 POP function, G904 can serve as multi-viewer to
display up to 5 images in one monitor. Standard 3 equal windows or quad windows multi-viewer in one
monitor at portrait or landscape directions are standard applications in G904.
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.
