Catalyst 10.4 Fixes EDID Issue for HTPCs

This problem has been around for so long, it’s slightly insulting that it’s taken this long to resolve. Those of you using AMD video cards and an HDMI receiver will definitely want to look into this.

The issue rears its head when you switch your AV Receiver away from your HTPC (or boot-up without your AV Receiver/ TV on and selected to your HTPC) you Video Card loses the signal and thinks that there is no longer any Monitor or Audio device “attached” to your HDMI port.  EDID override was possible using a registry hack provided at (thanks Tulli!).  However, the hack was device specific and was complicated to implement.
