    I hooked up my broken screen toshiba XP laptop to a external monitor with a VGA. I removed the laptop screen driver, and installed the new monitors drivers and was able to change the resloution to reasonable size. It worked great, for a day. Now the screen only shows the windows start up logo and then turns black. I know the computer is still running because i can still log into my accont when I guess the right buttons. HOW CAN I MAKE THIS WORK? thanks much.

    Hi minusblindfold, and welcome to TSG.

    Does your laptop have a function key for toggling between the built-in and external displays? If so, does using it let you use the external monitor?

    Are you able to get the external monitor to work if you boot up in safe mode?

    I don't know if I have a Toggling button. I know when I press F8, a list of options comes up. I've tried clicking enable VGA mode, but no luck. When I run safe mode the only thing that happens is a list of drivers comes up, but it does come up on the external monitor
    list of options by the way:
    safe mode
    safe mode w.networking
    safe mode w.command prot
    enable boot logging
    enable vga mode
    last know good configureation
    dirctory service restore mode
    debugging mode
    disable automatic restart on faliure
    start windows normally
    reboot
    return to OS choices menu

    If the function is available, it should be described in the laptop's user manual. You can also look on the key markings to see if any of them have a symbol that looks like a monitor screen


    I think you are describing the Windows boot up process that lists all of drivers and other files as they are being loaded. Does the Windows desktop ever appear or does the computer just stop, showing the last driver to load?

    I believe my toggling button is "F5" but I've tried that, and every other "F" button to no success. When I run safe mode, the Windows logo doesn't load. IT flashes blank and list a bunch of drivers, and just stays on that screen.

    Usually the Key Combo of Fn+F5 is required to toggle between the Laptop Screen and the External Monitor. Give that a try.

    I don't have a Toshiba laptop to check this out but from what I have read on line, you may need to hold down an "Fn" key while pressing the F5 key to toggle the video modes.

    I am starting to suspect that removing the built-in screen driver and replacing it with a driver for the external monitor may be the cause of the problem and don't know how to reverse it.

    EDIT: Hi dustyjay, it looks like I didn't refresh the page before writing my reply and missed your post about the Fn key.
