Monitor Tests Forum

Hello. I have an Samsung SyncMaster 740N monitor which I can overclock it to 85hz. But the problem is when I set it to more than 75hz there will be a box in a middle of the screen saying "Not Optimum mode:Recommend 1280x1024 60Hz" but the rest of the screen works fine. After a while the screen turn black and the box is return. How can I set it to not go to a black screen.Thanks
Sorry if my english is not good.

You can't. Samsung monitors usually won't allow more than 77 Hz.
