    Dual Monitor Problem

    I have a 23' LG screen through DVI-D and a 21.5' LG screen through D-SUB (VGA cable) I have an NVIDIA GeForce GTX 550 Ti. The second monitor keeps blacking out into D-SUB power saving mode. I have turned all my power saving settings off as well as my hibernate and PCI express. I have upgraded my PC power supply from 400W to 600W but am still getting the same problem. I have read that you have to set up dual monitors through NVIDIA settings but cannot find the way to do so. Everytime i go into the control panel for NVIDIA it has both screens up there. I have no idea what else it could be. Any help would be much appreciated.

    Are the drivers updated? Usually the control panel is included with that, but I've never had to use the control panel to manage dual screens. I was running dual screens without a problem on a 460. It sounds like either a cable or card problem, possibly.

    Err yeah update the drivers I don't know what that's happening. I'm on Dual Screens myself, nothing wrong here.
    Try to go to the visual/colour settings and 'reset' them. See if that helps.

    Occasionally one of my screens will dim after a reboot and doing that will sort it out.
    I have eaten all the popcorn, I left none for anyone else.

    Have you extended your displays through the Windows "Screen Resolution" (found by right clicking in empty space on the desktop) Quite often a second display will default to off, rather than mirrored like is usually the expected default.
