Testing an HDMI or HDBaseT Source's Response to EDIDs

6.5
The 780C HDMI and HDBaseT IN ports emulate an HDMI or HDBaseT sink device. Part of that emulation
function is presenting an EDID to a source when a sink device is powered and hot plug is asserted. The 780C
is provisioned with a default EDID from the factory. There are two standard EDIDs available with the 780C as
provided: 1) Standard HDTV EDID, 2) Standard A/V Receiver EDID.
However you can reprovision the EDID by connecting it to a sink device whose EDID you would like to use for
testing. The 780C can store multiple EDIDs. These EDIDs can be obtained either by extracting them from an
HDMI or HDBaseT sink device (e.g. HDTV, Projector, AVR, repeater or distribution device input) or by
importing EDID .xml files created using Quantum Data EDID Editor tools. For procedures on importing EDIDs
refer to Adding Reference EDIDs for Use in Testing HDMI
Note: Quantum Data has an EDID Library available for free at: http://www.quantumdata.com/edid/.
The EDID test of an HDMI or HDBaseT source device enables you to see how a source device responds to a
specific EDID or a series of EDIDs. The EDID could be a known good EDID or an EDID you have chosen
specifically for testing purposes.

Configurations for Testing an HDMI Source Devices Response to an EDID

You can run this test in two configurations: 1) with your source device connected directly to the 780C, 2) with
your source device connected to the 780C through a repeater device. In both cases the 780C is emulating an
HDMI sink to test an upstream source. These configurations are shown below.

Configurations for Testing an HDBaseT Device's Output Response to an EDID

6.5.2
Typically you run this test with the 780C connected to an HDMI source through an HDBaseT distribution
device. This configurations is shown below.
