8.10 screen resolution messed up

[Samuel Rohde]

I booted my computer and my screen resolution is messed up when I am logged in to my account. It took off half a task bar thickness(12 pixels) all the way around. I tried going into System > Preferences > Screen Resolution and I tried every resolution but all of them where the same. I am using an Olevia 232v 32" wide screen TV/Monitor. How can I fix this problem? I have never had this problem before.
