why is 60 htz dangerous for my eyes ?

dhkimboa · February 5th, 2002

I am currently using a 17' monitor
and the resolution I used to use was 1280 / 1024 running at a 60 htz.
but I change that resolution to 1024 / 768 running at a 85 htz.
people at another forum told me 60 htz hurts my eyes but I got no answer back when I asked them " why "
does anyone knows ?

60Hz? Man if I run anything at a refresh lower than 80Hz, my eyes hurt, literally. I don't know the scientific explanation, but if my eyes hurt, it can't be healthy for me

Now I'm on 1152x864@100Hz

February 5th, 2002

gives me a headache if my desktop is constantly at 60hz...also depends a bit on the monitor, and I dont have it with a moving picture.

**Xeven** · February 5th, 2002

I am at 100Hz@1280x1024 60Hz, will literally makes my head really hurt.. and my eyeballs ache as well ..

**Shiori** · February 5th, 2002

My monitor's at 800x600@75Hz....

yet my head still hurts
My eyes are still strained....

...from doing too many papers.

so no one with a clear scientific explanation ?

Its because at anything less than 80 or so herz you can see the screen updating and the resulting "flicker" gives you the headache (I dont know the exact how/why).
Put your screen at 60hz and look away from it so you can see it out of the corner of your eye and the flicker should be very obvious then do the same at 80 or so and it shouldnt flicker.

**Demigod** · February 5th, 2002

It differs with people. For some 60 Hz is fine, for others it's unbearable. Me, I have to put it to at least 85 Hz, otherwise I see flickering.

Enigma1982 · February 5th, 2002

I can't stand with 60 Hz
85 Hz is the best for me

February 5th, 2002

my monitor runs at 100hz.
(nice screen sync with PAL games too)

**Snake785** · February 5th, 2002

Well, I'm running 800x600 @ 60HZ. I see no flicker. I can't use anything higher because my monitor wont allow it (It's 7 years old! but it works great!

).

Quickdart · February 6th, 2002

Yay 7 year old monitors! Mine looks fine at 60hz, can't do any higher and the screen moves to the left if I go to 1024x768 resolution! WooHoo!
It's SUPER VGA compatible!

Ozzy · February 6th, 2002

I'm more worried that a certain Hz would damage my monitor as my Display applet warns.

**Zephon** · February 6th, 2002

I'm using 85Hz and anything below that makes my eyes feel "tired". I used to have a 14" monitor that only allowed 56Hz at 800X600. I either used a lower resolution(640X480@60Hz) or I couldn't stand in front of the monitor for more than an hour.

Why in 1024 by 768 pixels mode. the highest i can put is only 75hz ? why ? wat is hz mean ??

ahtze · February 7th, 2002

I just put optimal rate. wat rate is it going to use ? It is ok ?

It's probably due to the limitations of your monitor, or you may be using the wrong drivers. Check your monitor specifications and also try getting updated drivers for your monitor.

The problem may also lie in your videocard. Check that your card has a fast enough RAMDAC to display that resolution at that refresh rate.

"hz" refers to the refresh (or update) rate per second of your monitor. A setting of 60 hz refreshes the monitor 60 times a second.

It'll probably use the safest setting for your monitor (usually 60 hz)

When I try to put my monitor to 1024x768, the screen looks weird and the screen seems to be displayed in 3 columns (it's kinda hard to explain). My monitor claims to support that res but apparently not at least with the windows drivers. I tried getting updated drivers, but I guess my monitor is too old to have other drivers.

Hanamichi · February 7th, 2002

Mah monitor is at 60Hz , maybe thats why i get headaches . But how on earth do I change the freaquency ? No software or buttons on my monitor allows me to do so..

**Xeven** · February 7th, 2002

some stuff to look at:
1. Your monitor cannot support any frequency higher than 60Hz at your current resolution setting. (Try to see if you have higher freq settings at lower res)

2. Your monitor might require their own set of drivers (pretty much NEVER nowadays), try to go to the manufacturers website or something..
