I'm working on a HTPC video renderer and for that I need information on how to:
(1) read the EDID directly from the display (not from registry)
(2) read/write from/to I2C port
(3) check whether the display supports HDCP
(4) read the GPU product name, dedicated video memory size etc
I need this for all 32bit and 64bit Windows OSs beginning with Windows XP.
For NVidia there's a nice NVAP I header/lib available which allows all this (and more). Is there something comparable available for Intel GPUs? That would be great. Thanks!
Best regards, madshi.
I am also looking for a way to read the EDID of a display connected to my Intel graphics card. It looks like in 2010 Intel did not provide a public SDK for this purpose. Please let me know if anything has changed since then. Thank you.
