    Briefly, I've been using my monitor instead of the laptop screen for over a year now. Everything works fine. Suddenly yesterday the monitor went black! It's actually still functioning on some level but doesn't keep the display. I was doing something on the internet, possibly saving a password in RoboForm, maybe just wandering. There are no error codes or indicators.

    When I reboot, having previously changed the setting to dual - laptop & monitor, it briefly flashes the Vaio splash screen, then black, then briefly flashes the Windows splash screen. Then black. The laptop screen is fine. I've tried both 'Single Display - Monitor' and 'dual display' - Laptop as Primary; 'dual display' - Monitor as Primary, and in none does the monitor work - laptop screen always works.

    If I unplug the VGA output from the laptop, then plug it back in, the monitor briefly (maybe 1-2 seconds) shows the desktop images perfectly! Then black! It seems that everything is actually working just not properly! It's making me crazy. I did try downloading the most current graphics driver from Intel...nothing. The monitor continues to show a green light (indicating that it is receiving a signal). The audio (plugged from the monitor into the front of the laptop by a separate plug) continues to play thru the monitor.

    To Recap: Display on 'Monitor only' has worked just fine for a year. Now it won't show any image, yet is receiving the signal. When first plugged in, the monitor displays whatever is on the laptop screen perfectly with no break up or distortion -but only for 1-2 seconds. There are no error codes. Graphics file has been updated.

    Any help, ideas, thoughts would be greatly appreciated. (See below for hardware details.)

    Try another monitor or try that one on a different computer... that will tell you where the problem is.
