Ok this problem is getting interesting. So I recently upgraded to
Ubuntu Hurdy builds. Running with the included intel driver & latest
git tree I now see this for my 1920x1200 Samsung 243T. This data is
clearly wrong. So I'm wondering how the intel driver is not reading
the EDID correctly and falling to theses values. As you can see in my
previos email 1280x1024 @ 75hz is not valid for the Samsung 243T.
