INTRODUCTION
The VW-1312P 12-Display / 9-Display 4K2K Video Wall Processor is a powerful, most cost
effective, and fully real time data/video processor for multiple flat panel displays or projectors. VW-1312P
can support up to 12 DVI/HDMI outputs to expand the spectrum of video wall applications. With add-on
card design concept, users can therefore adjust the number of output ports based on different scenarios.
Meanwhile, with the very same chassis of VW-1312P, the bandwidth of the video, the controllability of the
module, and the input complexity can be further explored to either cost down the project budget or
enhance with the new features from the new I/O cards.
Thru digital transmission, the quality of the outcome videos is guaranteed. The output display is
grained up to 255 by 255 squares. Virtually any setups for the display layout can be possible by the
provided software. The VW-1312P allows you to input DVI/HDMI, VGA, Component, wherever positions
and whatever sizes you want for viewing. The embedded scaler converts signals from two of input
sources to match the native resolution of monitors, flat panel displays, projectors as well as
user-selectable output settings up to WUXGA (1920x1200). The VW-1312P sends the resulting
processed video thru DVI/HDMI interface to the connected monitors/projectors based on the display
layout. The layout can be readily modified to fit your applications and optimize visual effects. Typical
applications include digital signage, and broadcasting/education/ surveillance systems, etc.

EDID LEARNING
The EDID learning function is only necessary whenever you encounter any display on the HDMI
output port that cannot play video properly. Because the HDMI sources and displays may have various
level of capability in playing video, the general principle is that the source will output the lowest standards
in terms of video resolutions to be commonly acceptable among all HDMI displays. In this case, a 720p
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.
There is a methodto do EDID Learning as below:
Software Control: Please refer to the Operation Approach\ Software Operation (Page 13.)
There are four embedded default EDIDsas below,
1. Full-HD(1080p@60)-24bit 2D | 2ch
2. Full-HD(1080i@60)(720p@60)-24bit 2D & 2ch
3. Full-HD(1080p@60)-30bit 2D | 2ch
4. 4K2K@30-24bit 2D & 2ch
