Hi All,
Pardon me if this has been discussed before but I sure as heck can't find the
answer. Perhaps my googling skills aren't good enough.
Anyway, I have an AOpen DE 965-HG mini PC that has - surprise! - Intel 965
graphics. It has an HDMI-out port which I have connected to my 42" plasma
Panasonic TV. The TV is a little old (circa 2005) so it apparently reports the
wrong EDID information. It also needs to be adjusted for overscan. When I
try to run Linux (any kind, but currently Ubuntu 10.04) X server it picks up
the wrong resolution. With a different computer (NVidia graphics chip) I was
able to disable EDID checking to set my custom Modeline. I can't seem to be
able to do that with the Intel driver. It ignores my custom resolution and
gives me the first of two incorrect resolutions.
Could somebody please guide me in how to disable EDID so that I can view my TV
in all its HD glory?
Thanks!
Lucas
