INTRODUCTION
The VW-1404ZH 4-Display HDMI2.0a 4K 4:4:4 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 allows user to input HDMI up
to 4K2K@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 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 three embedded default EDIDsas below,
1. Full-HD(1080p@60)-24bit 2D & 2ch
2. Full-HD(1080i 720p@60)-24bit 2D & 2ch
3. 4K2K@60-24bit 2D & 2ch
