INTRODUCTION
The VW-1404ZH-C 4K 1x4 Video Wall Processor is a powerful, cost effective, and fully real time
data/video processor for multiple flat panel displays or projectors. Virtually any setups for the display
layout can be possible by the control software. The VW-1404ZH-C allows user to input HDMI up to
3840x2160/4096x2160@60Hz 4:4:4. And the embedded scaler converts signals from HDMI source to
match the native resolution of monitors, flat panel displays, projectors as well as user-selectable output
settings up to WUXGA (1920x1200). The VW-1404ZH-C sends the resulting processed video thru HDMI
interface to the connected monitors/projectors based on the setup display layout. The layout can be
readily modified to fit your applications in digital signage, broadcasting, education and surveillance
systems and optimize visual effects.

EDID LEARNING
The EDID learning function is only necessary whenever you encounter any display on the HDMI
output port that cannot play audio and video properly. Because the HDMI sources and displays may have
various level of capability in playing audio and video, the general principle is that the source will output
the lowest standards in terms of audio format and video resolutions to be commonly acceptable among
all HDMI displays. In this case, a 720p stereo HDMI signal output would be probably the safest choice.
Nevertheless, the user can force the matrix to learn the EDID of the lowest capable HDMI display among
others to make sure all displays are capable to play the HDMI signals normally.
The method on doing EDID learning please refer to the software operation section.
There are five embedded default EDIDs as below,
1. Full-HD(1080p@60)-24bit 2D & 2ch
2. HD(1080i 720p@60)-24bit 2D & 2ch
3. 4K2K@60-24bit 2D & 2ch
4. 4K2K@30-3D-PCM2CH
5. 4K2K@60-420-3D-PCM2CH(2ch)
