Wow, that was indeed a long thread to read through. I'm having a bit of a problem, possibly with PowerStrip or possibly with my video card drivers, and I was hoping someone would have suggestions. I was using an ATI Radeon 7000 with latest drivers (3.7), etc, with Powerstrip latest (3.45), and had no problems after I finally figured out how to get my Zenith C27V22 to take the >480p input. Everything was working just fine, I could switch through resolutions without issue, and could make real-time adjustments with PowerStrip to adjust refresh, move porches, etc. But, my games were running a bit slow on that card.
So, I upgraded to a Radeon 8500LE, and all my problems started. I did the smart thing and first uninstalled the video drivers, booted into VGA mode, installed the video drivers again, and got a fine 640X480 picture. Great. Tried to switch to my pre-defined resolutions that were set up for the 7000, and nothing happens. No resolution change whatsoever, and the settings in PowerStrip are uneditable. I thought it may have been my pre-defined resolutions that gave the problem, so I deleted them, but I was still unable to select one of the pre-defined resolutions and switch to it. So, I uninstalled PowerStrip, removed all PowerStrip settings from the registry, rebooted and reinstalled, but I was still unable to change resolutions. Finally opened my Windows 2000 display panel, and was able to change resolutions there, and it used the PowerStrip settings for the custom resolutions I'd added there.
So, I'm able to switch resolutions that way, but there's no way for me to adjust any settings on the fly, as all scan rates, porches, etc are locked and can't be edited. The only way to change any of this is to copy PowerStrip settings to my clipboard and paste them in as a new custom resolution. Which sucks, because most of the >480p resolutions come out to 33.8x hz, which doesn't quite sync up properly (top few lines run up in a strange way, kind of hard to explain).
I've tried redefining my monitor, that didn't help, tried all the settings I could think of for both ATI and PowerStrip, and feel that I must be missing something simple here. On the plus side, I can finally play Vice City at full frame in glorious 640x480p, but would rather up the resolution and use the full extent of my HDTV. Does anyone have any suggestions? Thanks!
