Disabling dual-monitor mode when not able to see anything

By crappymail ·
A friend just left a laptop computer for me to look at. The built-in, LCD screen is not working, but I was able to see things okay if I hooked up an external monitor.

Since I don't usually work with laptops, additional monitors, or Windows, I decided (like a dummy) to see if the LCD could be gotten to work by enabling the dual-monitor mode - not the option you can select through FN-F5, but the one that comes up in the "Settings" tab of the Display Properties.

Well, all that did was to leave the LCD with nothing, and then the external monitor with nothing, as well. Now, whenever I boot up the laptop, the only ways to get anything visible are Safe Mode and VGA mode, but I can't see, in either of those, how to switch OFF the dual-monitor mode. I have ever tried going back to an earlier System-Restore point, but that did nothing for the display settings.

As far as the LCD goes, I HAVE already tried the necessary FN keys for turning the backlight on and off, and for adjusting brightness and contrast, but none of those helped, so Durabook is giving me an RMA number for my friend to be able to send the computer back for repair/replacement.

For now, how may I restore the system to SINGLE-monitor mode, so that he will at least be able to see things by using an external monitor until he actually sends the unit back?

Well, it appears the restore point DID work, but just took a long time, and was hard to tell, at first, since I couldn't see anything that was happening yet.

As far as the responses my question received, thanks, but they were not needed, after all.

In fact, they seem to be rather questionable, at best.

Seanferd, to do what you suggested, it would have been necessary for me to SEE what was on the screen. Thus, this is not a valid solution, since I clearly stated (even in my subject line) that I was not able to see ANYTHING.

Tietokoneet, your suggestion seems questionable, at best. The key sequences you specified are just simple navigational sequences to open the Windows "Start" menu and to switch among active windows. It doesn't seem those would do much when one's screen is set as a secondary monitor without the "extend the desktop" option. In fact, I had actually tried such standard keystrokes already, to no avail.

Again, should anyone else have reached this subject because of having a similar problem, just go ahead into Safe Mode, and revert to a System-Restore Point prior to the time when the secondary monitor had been selected, but give it some time, since it may not appear to have changed anything the first time you restart the system.

At least you have it working anyway..

The option i gave you was a shot in the dark but at least you had options. The option you took was the right one.

Please post back if you have any more problems or questions.

That's great

My mistake. Since you had mentioned being able to interact with system restore, I figured you must be able to see something.
