Hi, I am helping a friend debugging the cause of some display
problems. It is a new Dell 20.1" Ultrasharp, 1600x1200 LCD panel.

The problem is the screen is not very consistent in terms of display
quality. On one part of the screen, the display is very sharp, on the
other part, there are some 'shadow' effects, or some kind of smearing.

The video card is an ancient Visiontek 32mb AGP, and it does not have
DVI output.

Could this be caused by some interference from the analog video
signal? Would getting a new video card with DVI help? Does this sound
like a LCD defect? Part of the screen is very clear, the other part is
not.

Thanks in advance.

Very old card has low frequency DAC and you can't tune
properly the monitor.
Buy a recent card to solve...
Also some cheap Radeon 9200 has DVI and decent analog output.
