Ok so I just installed my new XFX Radeon HD 7850 and when I turned my computer on and got to the desktop I noticed that my resolution was changed. I tried changing it to my original 1600 x 900 but it wouldn't let me. I didn't install the drivers because my internet adapter inside my computer was loose and my internet on the computer wasn't working. I uninstalled it because unless I can figure out how to change my resolution back to 1600 x 900 and I can get the drivers installed (A link to where to download them would be nice), I will be probably taking it back to CompUsa (Where I bought it). Help?
You need to install the drivers before you'll have the full range of resolutions available. It sounds like you're running off windows default drivers and there's nothing wrong with the card itself. If you can't get to AMD's website, the CD that came with the card wil lhave drivers on it that will work, even if they aren't the most current.
