Can someone explain how refresh rates work on LCDs? All the ones I've seen are rated at 60hz, but I didn't think LCDs actually had a refresh rate.

At 60hz on a CRT, it'd be really flickery. Is there alot of flickering on an LCD?
 
they dont work on lcd's. the image is either off or on. since there is not crt scanning in the image you dont not get a post phosperous decay, the flicker. although, settings have a "backwards compatible setting for the video card" is is not really a refresh rate setting.

note: this is why lcd's are comfortable to work with. the image is not causing the eye to constantly attune to the image. subconscience is how most perceive this but some can at a conscience level.
 
there is essentially no refresh rate, as the LCD does not need it.

my 191T's have 60hz and 75hz options, but neither produce a different result.
 
You can destroy an LCD by forcing it to run higher refresh rate than it wants to according to article I read (don't remember where).
The article said to let the LCD monitor setup software or the video card setup software pick the refresh rate.
They will always pick a conservative refresh rate (usually 60) that will not harm the LCD.
So I leave my LCDs at 60Hz and have no problems and pic is rock-steady and restful on the eyes.
I could never do that on my CRTs; I always had them refresh at 80-110 to save my eyes from headaches.
And like someone here already said, there's no noticeable diff that you can see (on an LCD monitor) whether its running at 60 or 75.
