    External Monitor flickering!


    Hello,

    I am using a new Lenovo y550P laptop and having problems with the external monitor. When I plug my external PIXO LCD monitor via the vga port, I get a constant flickering. I have tried installing and reinstalling all the graphics drivers for video card (geforce gt 240m), adjusting the refresh rates, tried 3 different vga cords, 2 seperate LCD monitors, and using different power surges with and without the laptop adapter, all to no avail. Please help!

    @ iggy:

    Yes I have. I've tried the 4 refresh options it gave me. The lowest settings (60 hz) causes the monitor to flash extremely fast while the highest setting (75 hz) reduces the flickering to about once every 2 seconds.

    I guess I have no futher suggestions other than to uninstall the drivers for the graphics and see if Win7 picks a better one or try a basic VGA and work back up to the latest. Sorry.
    Hopefully someone else may have a solution cause I'm stumped.
