refresh rate on my new lcd

First lcd I have ever had so bear with me. I see it can be set at 60hz and 75hz. Does it matter if I set it to 75? will it do anything? or should I leave it set at 60?
 
err. okay so according to that post anything higher than 60 is actually going to be a negative?
what about gaming? Cause I was playing prey and I was getting terrible tearing.
 
Tearing isn't because of the refresh rate. Try enabling VSync. Using anything over 60 Hz may stutter although my VP930b worked fine at 75 Hz (at least it seemed to). I got the info from X-Bit Labs on the refresh rate stuff and they say that's the way it works on all LCDs, and I tend to trust that.

yeah, as xtknight said, tearing is Vsync. Almost always. Tearing happens because the entire frame can't refresh at once; Vsync simply makes one half of the page or the other "wait" until the rest of the page is available. Vsync also stabilizes frame rates (but can usually lower them) at 60 or 45 or 30 or some "round" number like that, which is a side effect of what it does. As I really HATE tearing, I have Vsync on with every game I play and my GPU is strong enough that the performance hit is unnoticed.

Personally, i can't tell a difference between 60 and 75 anyway so I just leave it at 60.
 
I was surprised because on my old crt I didn't see tearing in prey.
I would think my 7950gt could handle it okay
but of course now my resolution is 1440x900 so that may hurt my perf significantly.


I am really surprised by how much I have to turn the brightness down. My old crt was cranked and this I have set all the way down to 25.
 
it's very probable that your CRT was set to 85hz or so, which LCD's cannot replicate at this point AFAIK...
 
Yup, with VSync off an 85 Hz CRT is more likely to finish drawing the frame buffer contents before the video card swaps it. I can't stand running current LCDs w/o sync; I see the tearing immediately.
