Good day & I'm new....So please forgive me for stumbling.

I have a Toshiba Laptop, 32 bit, Vista home prem. with ATI Radeon X1200 display adapter, Catalyst control.

Each time I boot, everything is good at 1280X800 for less than one min. Then goes to 640X480. I can get my resolution back by right click on the task bar ATI icon which will show me two “ATI Radeon X1200 series” choices. Clicking on the second one and selecting “Extended desktop” every thing else is grayed out on this choice. This corrects the problem until the next boot. and then right back to 640X480.

The first choice gives a list of resolutions, one choice is “Set desktop area to” but clicking on any resolution brings up the window telling me that resolution cant be located.

Once Ive corrected by “Extended desk top” then the resolution choices in the other ATI Radeon X1200 series allows the choice of resolutions.

Ive re-installed the updated ATI drivers (Twice), tried the Vista resolution change, Tried the Catalyst control Center... Nothing corrects the problem.

Id like to avoid this work-around, can any one assist in getting me back to the original boot. I have no idea what caused this.

Thanks ahead of time!

Realized I left something out. This might be connected because it started around the same time..... Sporadically and always on reboot my desktop icons that I set to medium view, return to classic. The right click menu that shows "View" continues to indicate "Medium" though they have returned to "Classic". To work-around, I must click on Classic, then medium to reset to my wish. Thanks

Alright. so it's good for a little under a minute then it drops. Sounds like some program hits it as it starts up. Check if you installed anything that affects video around the time it started.

You could also try and plug the monitor into your onboard card rather than the ATI card and see if that works.

Let me know.

I had tried finding a program that starts at the time this happens like you suggested to no avail. This is a laptop and I don't thik I understand your second idea. Thanks for anything you come up with.

YOU GOT IT!

You made me think about other programs being the cause and so I went over everything again. I had not closed a couple programs "I was sure of" (Right, yeah!). My Works Calendar reminder (WkCalRem.exe) must be corrupted. When I disabled it all went well.

One thing age has taught me " When we are absolutly sure we are right, we can still be wrong."

Much thanks, it is very appreciated.

I've had a similar problem, maybe related to upgrading from Vista 64bit to Win7 64bit, but every time I'd reboot, my screen would be its normal 1920x1200 for a few seconds, then change to 640x480. Finally tracked it down to something very simple. Right-click on program name in Start Menu>properties>compatibility. For some reason, there's an option to "run in 640x480 screen resolution", which was checked. This particular program was in the startup folder, and was the cause of the problem. If I took it out of startup, and opened it manually, it would do the same thing until I unchecked the resolution box. Put it back in startup, and no more problem. I know this doesn't sound exactly like your problem, but perhaps it will provide another clue. I sure wish I could have found this explanation when I searched for help, instead of spending hours tracking it down!
