Re: Display settings problem.
I have the same card. Try this. When you set the clocks to the way you want, near the bottom, there is a box that says "Apply these settings at startup". Make sure you click on it and put a checkmark in it. Then the next time you reboot, it will be using the overclocked settings instead of revertting back to stock.
