Before an EDID can be loaded to an input, it must first be copied to the matrix’s memory. Each
display’s EDID can be saved individually to one of the matrix’s EDID memories.

When the matrix is completely connected and turned on it will load the default EDID, which is the
highest common native resolution of the connected devices. (i.e. In the diagram below the default
would be 720p with 2ch audio. Multi-channel audio and 3D are not enabled on internal
mode, unless all devices have these features.)

On default, all devices in the diagram will work at 720p. If a device is not syncing or a different
resolution is required, internal EDID or EDID copy and load should resolve these issues. The AT-H2H
can copy multiple EDIDs to memory.
