Windows 7: Aero Snap not detecting screen size correctly?

Aero Snap not detecting screen size correctly?

Hey guys,

I've recently run into a problem with Windows 7.

As you can see, it isn't detecting my screen size correctly, which is weird to say the least since I've had no problems like this for some time. Please be advised that I am running a dual monitor setup, and that the problem only occurs on my secondary monitor (Acer 20"). However when I switched my display settings so that my Acer was the main monitor, the problem was still present. If you guys want anymore pictures, please advise me of so, and It will be done. As I feel adding pictures may help people who experience the same problem in the future.


Although updating the drivers did fix the problem, I found the source of the problem later on. FIFA 10 would resize my screen after each time I played the game. This is because FIFA 10 does not have the video resolution that is precisely the same as my 2 monitor setup. For this reason it would resize my screen to slightly wider than what my biggest screen is (FIFA 10 would resize to 1400 while my screen is only 1360).

To fix this everytime I finish playing FIFA 10 I simply right click on the ATI icon in my taskbar and reset the resolution. This fixes the problem. Here, as promised is a picture of my screen that shows how to fix the problem.

Thanks goes out to notsograymatter again for the help on the issue

Do you have the latest drivers for your graphics card installed?

And if so, why aren't you using the gfx card's software to adjust those settings?

Here are the drivers for:

ATI Radeon HD 5xxx series PCIe - Win7 x64

Download the driver and catalyst control center, that should allow you to change your desktop size, resolution, manage multiple monitors and all that.

Worked like a charm, so thanks for that. I can't believe that not having up to date drivers would do something like that.

Update: I recently found the more likely problem. It seems that everytime I play FIFA 10, it does this. I'm thinking it has to do with the game settings. It's funny that once I quit the game though that the Windows setting (or ATI) don't take over again.
