60 hertz or 75 hertz?
which is best on my moniter 60 or 75 hertz. when i put it on 75 my eyes feel like they are aching, is this because there not use to it? is there any medical issues i should be aware of ? or does it not make that much difference...cheers

Do you use a CRT or LCD?

if your eyes hurt, then use 60!

there''s not going to be much difference with an LCD screen , - unlike the difference 60 - 75 hz on a CRT would be, on an LCD it''s negligible - especially if the latter setting hurts your eyes.......

i''m not sure that having it at a higher setting makes it more of a medical hazard tho......

I agree. I have a samsung 4ms 19inch lcd.. i run at 75 no probs. i have run at 60 too for exteneded periods of time...i feel no difference on my eyes. It's different for and LCD than a CRT. but like he said then run at 60 if it hurts your eyes.

cheers, if there is no differance ill leave it at 60, i cant notice any differance really. on 75 its like the screen is popping out and hitting my eyes. they ache and i start to squint slightly.. /geek.gif' class='bbc_emoticon' alt=':geek:' /> anyway cheers again lads...

p.s. psu wasnt that hard to set up big tabs once i realised i had to connect more than 1 thing to each cable. it does not light up though. (got the black one from pc world). /thumbup.gif' class='bbc_emoticon' alt=':thumbup:' />

:) Glad you're happy with the choice you made on the PSU.

Regarding different refresh rates. In actual fact nothing much changes when you have an LCD. I'm afraid to say that the eye strain thing is in your head. Now before you go off thinking I'm calling you a psycho it's a very common thing to experience after being used to a CRT for some time.

It took me a little while to see that there was in fact no difference and I've since found solid information on why it's no different. What this info amounts to is that LCD's do not refresh in the conventional CRT sense therefore it is essentially a legacy option in the driver panel when no CRT is hooked up.

However.. you [i]might[/i] want to set it higher for gaming:

What governs the amount of frames per second you can actually see on an LCD is the response time. For my screen, that is 12ms... which roughly means that any given pixel on my screen can change to the next colour needed 83 times per second. So you could say that the max FPS I will ever see is 83. Now it's not as cut and dry as all that, because some pixels will update quicker or slower than that depending on what colour they are, and what they are trying to get to. Confused?

Now then, to break all this down into simple usefulness. There IS a good reason why you might want to leave it on 75 as opposed to 60 yet it is one thing I'm not sure about. [b]Does the nvidia driver will actually send more frames per second than the set refresh rate?[/b] If not.. you want that sucker as high as possible, because 72 FPS is the goal for fluidity on screen. If you are limited to 60, while being smooth, it's not quite fluid.

Because I don't know either way, and because there is no harm whatsoever in setting the refresh higher.. I put mine at 75.

isn't 75 Hz supposed to be more comforting on the eyes than 60 Hz ???

Well as long i'm concerned 75 is better for eyes in my case i set to 75 refresh rate in long term looks better.

Just a small advice look for your eyes very important.
