8K/2K Video wall controller (G904)

Quick Overview

G904 can build two MultiViewer with 3 split view in one UHD 4K monitor at landscape or portrait position at the same time. The aspect ratio of the image can be further edited. G904 is designed with 10 HDMI 2.0b inputs and 4 HDMI 2.0b output to support up to 8k/2k input and 4k/2k /60 output in each output ports. It can also build video wall for 4k monitor with all-in-one image across entire video wall as well as to display pixel to pixel 4k/2k content in each monitor. Multiple units can be cascaded to build big scale video wall.


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 input timings.

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 performance.

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. 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 3 split views in two monitor. The monitor can be at portrait or landscape directions separately.

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.
