LCD refresh rates – a myth?
With CRT monitors it is important to have a frequency that is compatible with frame rate (ie 75Hz for PAL at 25 fps).
But is it true that frequency rate is irrelevant for LCD monitors?
I am thinking of buying a 24″ LCD (1920×1200) to work via DVI with my RT.X2 / Premiere Pro system. Nearly all monitors seem to have a naitive frequency of 60Hz. I’m told that even if a manufacturer boasts 75Hz, the additional 15 are ignored anyway – and that you are better off leaving it set to 60Hz, even if you are working in PAL land.
I would really appreciate someone clearing this up.

We own a monitor (LH1760) from Panasonic that has a 120 Hz refresh rate. It uses black insertion.
It does make a difference in high motion scenes, but is also gets flickery in more static scenes due again to the black insertion. And don’t forget that unless your camera shutter is set that high, you likely won’t see a difference anyway.
The bottom line, unless you are spending some serious money on a broadcast monitor, and you do a lot of high speed sport shooting, you probably shouldn’t worry about it.

Thanks Vince. I’m considering a fairly low cost Dell Ultrasharp 2408 (A01 revision) for use as a client monitor. For DVI input it fixes the frequency at 60Hz and can’t be adjusted.
