Input supports up to 4096*2160 @60Hz, 7680*2160 @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*2160 @60Hz output resolution in each channel. The range is from 800-7680 in horizontal and 720-3840 in vertical. The maximum pixel rate is limited to 600MHz. Output refresh rate is selectable from 24/30/50/60/100/120Hz. 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 color adjustment in Brightness, Contrast, Hue, Saturation, Sharpness, color temperature and discrete RGB gain adjustment. Automatically detect and process HDR BT. 2020 input signal and output with full color 4:4:4 RGB SDR signal. 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. 3 split views and 4 split views MultiViewer function is embedded. PIP image can be from 4k/60 source with PIP image size from 320*180 up to 1920x1200. It can be located at any location in one screen. Both main and sub-images can be flipped and rotated at 90/180/270 degrees and quick seamless swap. The cropping range and position in both main and sub-image are adjustable. Maximum display windows in the video wall with 4 monitors is ten.

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.
