colored halos around text when using DVI connector

I have a Sony LCD monitor and a Transcend ATI Radeon 7000 display card
(running under Red Hat Linux 9.0, if that makes a difference). I am
using the DVI connectors on the display card and the monitor. For a
while, everything works fine, but inevitably persistent colored halos
appear around black text on a white or grey background.

If I switch to using the analog connectors, then the problem goes
away, but I would prefer to use the DVI connectors. Endless fiddling
(including power-cycling, switching resolutions and back, unplugging
power and video connectors, etc.) with the monitor will not make the
problem go away, but rebooting the computer will... for a while. This
makes me believe that the problem is with the video card, and not with
the monitor.

Any ideas on just what is going on, and how I might fix it? (This
happens on two different computers that have the same model monitor
and video card, so if the problem is with the video card, it isn't a
faulty unit, but rather a design flaw or some sort of
misconfiguration.)

Which Sony monitor supports DVI?

What I have found to work for me is having the font size set to a size that
eliminates the haloing. I'm using a differant setup though.
