Windows 7 thinks I have dual display but I don't RRS feed

  • Question

  • Whenever I restart my PC, the mouse cursor movement is not bounded by the right hand side of the screen. If I go to Display settings, resolution, it shows me that I have 2 monitors, but I only have the one. Choosing "Detect" sets it back to one monitor and the cursor behaves correctly. However, next time I reboot, it reverts to the dual-monitor display settings and I have to go back and do it again.

    Can anyone tell me how to make it detect the monitor correctly on start-up?

    I have a Samsung T240 display, and an ATI Radeon HD4800 graphics card, on a Dell XPS. I don't seem to have an ATI control panel on the PC.

    The Catalyst Control Center provided with the ATi Windows 7 drivers has been very stable for me - I'd recommend installing it, and seeing if it solves your problem.

  • Hi Moods

    Alex is correct.

    This behavior has been noted before with some of the later ATI graphics cards.

    Thank You for testing Windows 7
