External Display help?

[michaelwmc]

First of all, thanks for reading!

So, I plugged in my external monitor, then set the display preferences to "show desktop only on 2". All was great. Then I had the bright idea to experiment with different resolutions and see the result. Result: my external monitor didn't like the first one I chose, and now it just shows a black screen saying "signal out of range". Being that my laptop screen was off due to my "only on 2" setting, I have no display on either one. When I unplug the external monitor, I can use the laptop just fine, but as soon as I plug it back in, it remembers my brilliant settings and the external monitor goes off, as well as the laptop one, so I can do absolutely nothing.

I tried restarting in "safe mode", and somehow that got it back to the default setting of "duplicate these displays" which is awesome, because I can use the external monitor again. Only problem is that if I choose "only on 2" it still remembers my retarded resolution choice and I'm blank again ("out of range...")

So... is there any way to reset the resolution on the "show desktop only on 2" setting back to it's default? The only way I can access the options for that setting is by selecting it, and that turns off my displays...

Thanks again in advance!! I bow to all the gurus!

Michael
