If use the xrandr command and set a wrong resolution/freq/..., can a break my display devices?

For instance, by setting a very high refresh freq that one of the video devices involved (video card, monitor, ...) does not support.

In the early 90's there was indeed the danger of breaking CRT displays when setting too high frequency, but I don't think this is still a big problem. Modern CRTs should just refuse to work with unsupported frequencies. Still with any CRT there is some danger, at least this is what wikipedia says...

Wrong resolution doesn't do any harm.

+1, not yet accepted... let me play with the display config until I get the one I want, if I break the display in the process I won't accept you answer :) – Toto Oct 6 '10 at 19:08
+1 @Toto, dude... you made my day! And +1 @fschmitt, because of Toto's comment – Stefan Oct 6 '10 at 20:08
OK @fschmitt... accepted. I couldn't set up the resolution I wanted, but I didn't break anything in the process either. Thanks! – Toto Oct 7 '10 at 17:52
