Additional information
DVI resolution higher than 1280x1024 is not supported on A30, A31,
and T30 ThinkPads.
But this doesn't say explicitly that it's a hardware problem. The noise
isn't that bad. It's very very close but not quite. Any ideas?
That is pretty close to saying it is a hardware problem.
As others have said, hi-res DVI is a suck-it-and-see; basically the DVI
spec doesn't go above 1280x1024, so manufacturers have a harder target
supporting anything higher.
I have a Matrox G550 driving an iiyama flat screen at 1600x1200 with
DVI-D, even though the card is only supported upto 1280x1024.
The picture is good, but there is some shadowing.
The analog-to-digital on good quality flat screens has improved
a lot over the years. Can you get an acceptable picture using the
analog signal on the DVI port (you may need a DVI-A cable instead
of the DVI-D cable you are probably using) ?
It is sad, but analog signals may outlast DVI-D :-(
