Artical in CPU magazine explains something interesting about XP refresh rates and eye strain.
Sunday, March 16, 2003 by IPlural | Discussion: WinCustomize Talk
It seems that no matter what the performance settings on your Monitor and Video card allows.
By default without making use of the tweaking software that comes with most driver cd's, XP
will not allow your refresh rates to exceed 60 which can and does cause headaches, eye strain,
blurred vision, etc after a period of time looking at the monitor. From what the artical states
you should set your refresh for monitor and videocard to at least 75 - 80 to save your eyes.
Higher if they will allow it, you have to use a utility to do this, and you also have to make
sure it loads on boot up as Windows XP will return the registry settings to the default of 60
on the next boot...
thought if anyone was noticing issues like this, it might make a difference for you..

Dog gone it. I just checked. Sure enough mine was back at 60 again. And yes it makes a differance especially if you view the screen from an angle and a distance. I noticed this while pouring a soda the other night. I've reset it a couple times but thought I had it. I would like to know of a sure fire way to solve this.
Any body know where to grab such a utility, or tweak.

Well you can do a videobios flash but that dosen't do much. Do you have service pack 1 for XP? that helps. As for tweaks, Nvidia has a tweaking utility of there own that might help.

nView Desktop Manager. I tried a couple things before too many darn switches. I wish somebody that has neeper knowledge could show us the magic button. 60 refresh is archaic on a modern monitor.

SP1 might address it, wait a second and I'll go inside and get the link to the freeware utility in the artical for doing it..

I don't think SP1 does fix it though, Kona, do you have the tweak app for your vid card installed and enabled? also it might have been solved with your driver set...

Yeah I have it installed and running. It is call SiS utility tray. But I am running a SiS 64mg card, not the nice nVidias.

hey, it works and does a good job of it too 
the utility will keep XP from messing with the refresh, I know it was bothering me and I could not figure out what was happening to it.. I have a 200 box with the monitors sitting side by side and you could really see the difference, the XP box has the GForce in it, but I don't load the tweak because I noticed it sets up a udp link back to their servers...
or did, newer one might not

Right on! I ran the programdouble checked the results in display properties, adjusted the screen left and up and I am now running 800 x 600 with 144 refresh where I was stuck at 60 before. And that is what the monitor packing box said I was supposed to be getting. I have already backed up this dandy little utility and a copy of their web page to my back up HD.
Thanks a whole bunch. I owe you a dozen bottles of asprin.

dun no...it's an export version though? I'll have to get the link to the site of soeone who has been pushing to get otehrs to help get MS to remove that default. I do know my Viewsonics and NEC's all kick back and so do the vid cards on reboot, well they used to...

Hey Jafo try something in the 100 to 140 hz range then you'll see problems. Most high end cards require those high rates.

Why?
This little crae always runs at 60Hz. Latency is high enough, 'cause I only see flickering/screen refreshes from the corners of my eye.

Or if not the card, the monitor. My flat screen dose not like anything less than 100 or 95 hz but my gateway likes 75hz

Why?
because for some people 60 can very well be the cause of eye problems headaches etc...
if not fo ryou fantastic
But I know that when I was doing mechanical design for a short time in 1989, after staring at the monitor for hours on end, even looking away to foice my eyes to give them a break, I would always leave with a raging headache...
even now, with my displays set to 1280x1024 and my sitting in front of them all the time, if I am more than five feet away from the cable box the number for the time or channel it happens to be on are nothing more than a lime green smear...

I run mine 19" at 1600x1200 75Hz if windows was reverting to 60Hz tust me I'd know all about it...at 1600x1200 60Hz its is physically impossible to look at the screen it hurts your eyes like hell. I think whoever wrote that article must have been reporting a personal experience and not something that applies to everyone...

kona....graphic cards [modern ones] may be able to push refresh rates to silly levels....but feel free to fry your monitor as that is always going to be the weak link in the chain.
Anything much more than 75hz is of little improvement. It's the 50 to 60 hz level that causes eye problems, though again it depends on adjacent power frequencies...in Oz that's 50hz [240v] which is the source of much of the flicker....hence 100hz televisions giving a far more 'static' image.
I'd be loath to push any cathode ray tube over 100hz....over push 'em and they just go black...permanently...
