How to tell intel graphics to use my custom EDID file?
xorg;intel graphics;edid
Assuming you're talking about X, you can add a CustomEDID option to the Monitor section of your /etc/X11/xorg.conf.  For example, I have the following in xorg.conf on my mythtv box:Section Monitor    Identifier LG 42LD560    VendorName GSM    ModelName LG TV    Option UseEDID True    Option CustomEDID DFP-1:/etc/X11/LG-42LD560.edid.binEndSectionI did this years ago and I can't remember where i got the edid file from.  I think I may have extracted it with get-edid from the debian package of read-edid (I very vaguely recall something about getting a corrupted edid in X but it was OK if fetched from a VT before X started)
