G904 4CH UHD Video wall controller

Quick Overview

G904 is multi-function signal processor with 8k/2k 30Hz, 4k/60Hz input and 4k/60Hz 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 7 contents in one UHD monitor. Multiple units can be cascaded to build big scale display system.

 

One G904 has four 4k/60 output channels. Each channel has 3x HDMI 2.0 inputs (one port is shared with two channels) and 1x HDMI 2.0 outputs. Input supports up to 4096*2400 @60Hz, 7680*2160 @30Hz or 2160*7680 @30Hz with 4:4:4 chroma sampling. Two HDMI 2.0 loop out ports provide daisy chain connection for multiple unit cascade in large scale display system.

Programmable output supports up to 4096*2400 or 2560*3840 @60Hz output resolution in each channel. The range is from 800-4096 (8 Px/step under 230MHz. 16 Px/step above 230 MHz) in horizontal and 720-3840 (with 1 pixel/step) in vertical. The maximum resolution is limited to H * V < 9,830,400. Various input sources and input timings are supported, 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. BT 2020 HDR 10 signal processing is supported 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 channel. 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 are 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 in the video wall with 4 monitors is eight.

Through the combination of PIP/POP, G904 can serve as multi-viewer to display up to 7 images in one monitor (6 split views + one PIP). MultiViewer with 3/4 split views and 6 split views in one UHD 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.
