Edid Set Up

When the matrix is completely connected and turned on it will load the default EDID, which is the highest common native resolution of the devices. (i.e. With devices connected that range from 720p, 1080p, 2 channel audio, multi-channel audio and 3D, the default resolution will be 720p.

Multi-channel audio and 3D are not available on default unless all devices have these features.)

There are two options when setting up EDID: Default and Copy. In order to have any options other than default different EDIDs must first be copied. The AT-H2H-44M can copy up to 4 EDIDs to memory.

To save an EDID

If you’re having compatibility issues the H2H has a built in EDID management system to enable specific resolution or audio format to be locked in to a source. The first step is to save an EDID to the H2H’s built in memory. Save up to 4 unique display EDIDs.
