Monitor refresh rate

[chuwawa]

Hello, what is the optimum refresh rate on a monitor. Recently my mother tried to play freecell on my computer and said it was so blurry and grainy that she got a headache. After that, I tinkered with the refresh rate and couldn't really notice a difference with any of them at all.

I set it to 85hz...As far as eye health is concerned, is higher better?

thanks

yeah, the higher the better I had my monitor at 60hz for a while and I got horrible headaches, my uncle(a computing genius) told me to up it to 75hz, 85hz is the minimum you want to go for crt monitors.

It depends on the individual. For CRT, 75Hz is quite adequate. If you can't see the flicker, then there is no need to raise the refresh rate.

no, although you don't see the flicker, your eyes try to adjust to that changing flicker and sometimes you don't even see it, so crank up the refresh rate as high as possible, but you are right, it does depend on the individual in some cases.

higher is better. look off to the side of the monitor and you will notice the flicker in your peripheral vision if its not totally noticable to you. most cheap monitors don't have high refreshes though. back when crts ruled higher end ones could do 100+hz at many resolutions. if it still bothers her get her a decent low response lcd

I assume this is CRT, not LCD, and that this is a display issue, not a vision problem.

Blurry and shadowy (ghost images) could be symptoms of bad on-board video implementation or too high of a resolution for the video card, cables, or monitor. Refresh rate in theory shouldn't affect the sharpness; just the flickering; but sometimes there could be other issues. I'd drop the resolution first to something low, like 800x600. If it clears up, then either live with it, or try different different cables, video cards, and monitors, in that order, for higher resolution.

If you are looking at text and not pretty pictures, then
100 is way too high...text gets blurry.

85 hz, perfect.

Depends on the quality of the monitor. My 21" Nokia 445Pro runs at 120Hz, and everything is very clear.
