Screencasting resolution

[ MP/2600XT/ACD 20 ]

Is it ok to reduce the display resolution to say 1280x800
for screencast recording?

I read warnings about using the wrong monitor resolution
in the past, but those warnings apply to traditional CRTs?

Thanks.

 

In the past having the wrong refresh rate could damage a monitor,
or so I'm led to believe:

I don't think having a non-native resolution is likely to be harmful,
but I'm just double-checking.

A low non-native resolution is useful for screencasting because
it can reduce movie file size without reducing text size.
Although it looks fuzzier at the time of recording, at playback
time it is pin-sharp.
