it would be nice if the Intel Graphics driver would support overriding EDID information like described in this document from Microsoft:
Why is this needed?
In a common HTPC (multimedia PC) setup with a PC, AVR (audio video receiver) and a television, the EDID information stored in the receiver & television that is passed to the PC determines the video and audio capabilities like: supported resolutions, supported audio formats etc ..
The problem is that very often the system only "sees" the EDID information of the television, and not that of the receiver, and so you don't get support for audio formats like DTS, DTS-HD, Dolby TrueHD that are supported by the receiver ...
The latest Sandy bridge CPU and corresponding chipset support all these sound standards, but they often not useable cause of these EDID problems.
Actually it really does not matter what video card / integrated graphics you use, NVidia and AMD graphics have the same problem, but their drivers
allows people to override the EDID information like is described in the above linked document from Microsoft.
Please implement this stuff, shouldn't be that hard to do, for one of you senior driver programmers it's probably just a few hours of work ...
