EDID LEARNING
The EDID learning function is to resolve audio and video playing issues at HDMI output port.
Because the HDMI source devices and displays may have various level of capability in playing audio and
video, the general principle is that the source device will output the lowest standards in 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 of playing
the HDMI signals normally.
The method on doing EDID learning please refer to the software control section (Page 6.).
There are eight embedded default EDID as below,
1. Ultra-HD(4K2K@60) – 8/10/12bit 3D HDR video & 7.1ch audio
2. Ultra-HD(4K2K@60) – 8/10/12bit 3D HDR video & 2ch audio
3. Ultra-HD(4K2K@30)(4K2K@60 420) – 8bit 3D HDR video & 7.1ch audio
4. Ultra-HD(4K2K@30)(4K2K@60 420) – 8bit 3D HDR video & 2ch audio
5. Full-HD(1080p@60) – 12bit 3D video & 7.1ch audio
6. Full-HD(1080p@60) – 8bit 2D video & 2ch audio
7. Full-HD(1080p@60) – 8bit 2D video & 7.1ch audio
8. HD(1080p@30)(1080i@60)(720p@60) – 8bit 2D video & 2ch audio
