Fix

I had this problem
---------------------------------------------------------------
I installed windows 7 two days ago and everything works fine for me except one.
I can't run video games on lower resolutions. For example, I use to run counter strike source on Vista with resolution 1280x1024 (LCD) and Aspect ratio ( normal 4:3 ) and it was working perfectly. Now when im running counter strike source at this resolution I can't see the menu normally the screen look too narrow (black at sides) . and this problem is not only on counter strike with other games i have the same problem i can't lower the resolution.

Sorry my english is limited

just right now , i found the solution i installed old vista driver for my video card on windows 7, this one is 182.50_geforce_winvista_64bit_english_whql and it helpd a lot, it fix this problem.

I think If you have similar problem you can fix it by installing old driver for your video card. ( i installed Vista driver for my video card and it works!!! )

I hope this will be helpful.

Do not do this. There is no need to downgrade your graphic card driver. That is NOT the issue!

I had that same problem all you need to do is simply open NVIDIA PhysX Properties.

Then go to Change Flat Panel Scaling and select Use My Display Built-in Scaling.

That should do the trick. And you don't downgrade your driver.

Correct, and he knows this as i informed him here.

When YupYup told me about this option i could not find it anywhere i was searching this option for houres and no result , but i searched in google to find out about this Flat Panel Scaling and people were writing that new drivers does not have this option , there were some methods how to enable it but neither of them worked on my computer.

If you can please put the picture or put a small explanation how to enable this option it would be great !
it will help many people!

Open the Nvidia control panel by one of 2 methods. See pic for settings.

1. right click desktop then left click "Nvidia control panel"

Or

2. left click on "Nvidia control panel" icon in your computers control panel

I dont have this option , Look

After you told me about this option I installed 3 different version of drivers none of them had this option .

It seems the drivers think you have a CRT monitor, i would suggest installing any drivers you might have for that monitor or cleaning out all the old video drivers from your system and install again.

Seems promising , ok thank you again for good ideas :)
