whats the difference b/w refresh rates, what are higher refresh rates good for?

me thinks the higher ur refresh rate the sharper the image or something like that
good for higher screen resolutions ul know if u get it wrong as ur eyes will start to melt and ul get brain ache :salute:

iv got mine at 1024x768 @70 its easy on the eyeballs:rolleyes:

you should always play at 85 or higher with refresh rates anything lower than 85 seriously damages your eyes in the long term. I play at 100, the higher it is the better theres less strain on your eyes but be careful as some monitors dont support high resolutions and forcing a higher resolution then your monitor can handle can damage your monitor!

The electron cannon inside the picture tube sweeps across a mask in the front of the tube (right behind the glass). In a computer monitor this is done progressively (one sweep from left to right covers the entire screen unlike most TV's which only takes half (called interlacing)). The number of sweeps or updates it does in a second is refered to as Hz. 60Hz = 60 updates. Most people can actually detect this update when running at 60 (known as flicker) so it is recommended to increase it to 72 or higher. I think 85Hz is a good compromise between the loss of some clarity (most monitors will loose some clarity when you increase the refresh rate) and obtaining a flicker free picture. I doubt you will notice anything above 85Hz. This also means that the monitor Hz determines how many pictures you see per second even if your graphic card is drawing 200FPS.

so is 75hz a good refresh rate, its the max my lcd can go to.

menace, by looking at ur specs u run on all high right, do u get any pauses?

LCD screens are different, they dont update in the same way as a monitor. You don't see any flicker on those. You should start at 60 and try moving upwards and simply use what looks best. BTW you don't have your vertical sync set to always on in the nvidia control panel do you? Considering that score in 3DMark01...

Generally, the higher the better. It will hurt your eyes less. I used to have a CRT monitor on 120hz refresh, however it killed my eyes after a few hours. My LCD runs at 75hz, and I can stay on it for hours.

well, ill run it again, and see what i get. is 3dmark05 better or is it basically the same.

3DMark01 reveals more about your system performance than 3DMark05.

Generally Hz = Max FPS (on a CRT).

V-sync ensures that gfx cards FPS is synched with Hz of monitor and this keeps the FPS below or equal to the FPS your monitor is able to render, to minimize tearing of frames.

If V-sync is disabled all frames the gfx sends to the monitor is sent to monitor without syncronization, and thus any FPS counter would show the FPS the gfx produces, but the monitor is only able to show the number of FPS = Hz, it can't magically show more.

That is why one would never use v-sync on in benchmarks as it will top out at the capablities of the monitor instead of gfx card.

Generally in games, v-sync is a good thing, if your gfx card produce more FPS than Hz.

If your gfx card isn't producing enough FPS to get past Hz, v-sync might as well be disabled. Tearing is often worse if FPS > Hz if I'm not mistaken.

I run at ultra high and get no lag or pauses what so ever, pretty cool :) and i load up the game in about 10 seconds.

LCD's use response times ie. 8ns, 10ns, 20ns. The lower the better, in theory. CRT's use refresh rates in Hz, the higher the better.

You should only set your refresh rate to the lowest rate that is comfortable for your eyes.
60Hz is a huge headache waiting to happen for me but I can look at a 75Hz monitor all day.
Once you have it set at a comfortable rate then leave it, there is no difference in performance unless you have vertical synchronisation enabled.

60-75 if u want to melt ya eyes :p

I moved up to 100 with my new comp and it was very odd and uncomfortable but stuck with it and now my eyes have gotten use to it.
