[ale] Can Bad Video Settings Fry LCD Monitors?

[Chuck Payne]

I have seen it back in the day, if you didn't configure it correct, do this
thing were the LCD look like it was being cooking changing into different
colors before going black.  I did loose a dell 15" because it couldn't
handle the refresh rate of the card I had, but this was like back late 90's
and early 2000. Also, this was XF86Free and not Xorg, where you had to edit
the config file.

But Now-a-day Xorg does a good job, if the card doesn't work with the
Monitor, you only get a black screen.
