ATi and the Case of the Disappearing Screen Resolution

Heya, I have an ATi 9800 Pro.

Ever since I've moved from nVidia to ATi, I've had this same problem. It's not a big deal, but keeps on happening and annoys me everytime.

What happens is, every once in awhile, for no particular reason that I can discern, when my computer starts up the screen refresh rate is off so that the screen is shimmering. If you go into display properties (running XP BTW), every thing is set correctly, and the monitor refresh rate is a reasonable 75Mhz or 80 Mhz, but still the screen is shimmering like it's a slow refresh rate. In order to fix it I have to change to a different setting, such as if it's currently 75 I switch to 80 and visa versa. It will work fine for a week or so and then one day I'll start it up and it's doing it again.

I've done some searching but no solutions yet. Anyone have any bright ideas on a fix?

Do you have the degauss option on your monitor or an auto-resolution detector? I use the latter one and it always clears up any problems with my images. However, I only have to do it once for each new resolution/frequency setting. Sorry, probably not much help, just trying to brainstorm.

Isn't there 3rd party application that locks your refresh rate? I seem to remember various people disucssing it here at one point.

I'll check for an auto-resolution setting, that's a good plan. Maybe it's something local to the monitor, although I don't know why I wouldn't have been having problems when I ran nVidia too, I've had this Samsung monitor for quite a few years.

An app that locks the refresh rate would be good too, if anyone's seen one around.

Another funny thing is that whenever I update the video drivers, the control panel app that ATi tries to install always fails, so I don't actually have the ATi stuff running. I just adjust everything through XP, where all the particular ATi settings are present.

In order to get the control panel stuff to work you have to manually uninstall the driver and the control panel prior to installing a newone. You also net Microsofts update for Net Framework 1.1 or something like that. ATI goes through a description of this process on ATI's release notes on their download webstie.
