Even on Linux things don't always work as intended. The reason I am familiar with the EDID information is that my display stopped working after a kernel update and I tried to figure out why. It turned out that my AV receiver didn't like the VIC field being sent in the HDMI infoframes[1]. There is a surprising amount of communication which goes on between the graphics card and the monitor in a modern system. 1: Bug 50371 - [BISECTED] HDMI display blank unless VIC set in AVI infoframe https://bugzilla.kernel.org/show_bug.cgi?id=50371 https://bugzilla.kernel.org/show_bug.cgi?id=50371
