I have a Planar 20" PL2010M LCD monitor. I attached it to an Athlon 64
system running FC6 and using the nvidia proprietary driver (the latest
available). I tried (foolishly) the 1920x1080 interlaced output. The
monitor said it was outside the range. I reset to 1600x1200
noninterlaced and everything was fine. Later I connected a similar
computer (running FC5) that was displaying 1920x1080i (same nvidia card
- 5700LE or such). I noticed my mistake right away and I immediately
disconnected the monitor. Now, the PL2010M won't display anything. The
on light switches quickly from green to a constant yellow and displays
"no input signal" on the screen regardless of whether I'm using the
analog or digital input. I can no longer bring up the setup menu (e.g.,
to change from analog to digital) - no menu whatsoever. I called Planar
and they said it wouldn't damage the display but it seems like too much
of a coincidence.

Unless you have 20 y/o CRT, your LCD/CRT will simply shut down if you
try to use an invalid resolution/refresh rate.
Some monitors will not display the OSD (E.g. Menu) when connected to
invalid display source.
Just disconnect the monitor from the machine and/or fix the X.org
configuration and the menu will work just fine.

You are off by about 10 years. Those did not come about until about 1995-96. Some flat panels were worse. (I have an NCD flat panel that got damaged by bad frequencies.)

What was the date the displa was made?
