Samsung DVI Refresh Rate

[SnowyEnigma]

I have a samsung 191T+ running at 1280*1024. The "refresh rate" before was 60, I checked teh "display refresh rates only suppored by the monitor" or something and 75hz appeared. I thought "DVI doesn't have refresh rates, and niether does LCDs, the pixels only change when they need to". So my question is what's the difference between 60hz vs 75hz on a LCD monitor, and could it damage my monitor since I unchecked the "display refresh rates supported by the monitor"?

I have been running my 191T (black) at 75Hz DVI for months, looks great, seemed to clean-up the desktop looks a bit, I am really not a graphics expert, so I am not sure as to why it does in this case, but it did.

I would use 60Hz. LCD's don't refresh the way that crts do.

LCD pixels are all on all the time. CRTs have a beam scanning the screen to make the phosphor coating glow until it comes by the next time.

So, refresh rate is meaningless on LCD screens in terms of image quality, it just puts a limit on how many times per second the contents can be updated.

But since the fastest LCD screens just so reach the 16 microsecond switch time limit imposed by a 60 Hz update rate, this also is a non-issue.
