For the past couple of weeks I have had to strain to look at my monitor. Its not that I can't see it, its just that it hurts my eyes. Also I am starting to get headaches when I look at it for long periods of time. Its almost like I have to squint because it bothers me too look at it.

Has anyone else had this problem? Please let me know.

Thanks,

Travis

What kind of a monitor, and what size? CRT (TV-type), LCD, Flat Screen? what?

Maybe time to get an eye test done :)

I had a similar problem a few months back; turned out that my glasses needed to be changed.

Just went for an eye exam about a month ago. They updated my perscription and sent me home.

Put a white screen up (blank word processor document) and look away from your monitor so you see it in the corner of your eye while looking ahead. Do you see flickering? If so, and it didn't used to be there, the tube may be dying or I don't know what-all else. Those flickers will do what you describe, though.

Otherwise talk to a doctor/optometrist.

The answer is plain and simple. Change your refresh rate to a higher one eg 75 Hertz
 12/25/2004 09:06:56 PM · #8
Yep, IF that's the problem. That comes agfter he isolates the problem. One step at a time....

Absolutely, 75 Hz is really the minimum. That minitor should be able to do 75Hz at at least 1280x1024.

Right now it says 38khz 60hz how do I change it?
 12/25/2004 10:03:58 PM · #11
Depends on your operating system how to get to that control. I'll leave this to the computer geeks, I'm only passable at my own system.

But yep, that's likely to be your problem.

Nevermind I found it. 75hz you say I will try it.

I tried this after I adjusted th HZ. I noticed I can see alot of flickering going on. Looks like little lines going across my screen.

there is a range of values that your monitor can display
there is a range of values your vide card can produce.

they need to match up to stop the flickering.

I have an old monitor that will work fine unless i play certain games that use certain 3D modes. then it gets all funky. Perhaps you installed a game or ran something that did not reset things properly.

DIg out the paperwork that came with your hardware and see what is listed. If no manual, than find the model umber of each and look it up on the web.

Usually you get some settings that function, but give weird side effects, and some that work fine. You can try adjsuting the color depth, but i doubt that will help this issue.

And sometimes it's just a good screen gone bad... (sad slow music plays)

Lighting in the room may also have something to do with this .

like they said up the refresh rate to the highest your monitor will support and the eye strain will go away.. I had the same problem back when I first got a computer and after discovering the refresh rate could be changet I was a happy headache free camper

Chrome has the same monitor and has been complaining about the same problems.

I had the same problem with the Dell monitor that shipped with my Dimension 8200 computer. Not only did it give me headaches but made me downtright nauseous. After about a week of trying every adjustment that Dell tech support could think of, to no good effect, I sent it back. As it was their top-of-the-line monitor, I decided to go with a different manufacturer.

I have had, and at times continue to have this problem, when I spend long periods of time in front of the monitor, especially when doing lots of reading off of it. Use of a monitor can be very hard on the eyes causing strain and fatigue, especially with extended use. It may be wise to take frequent breaks if this applies to you.

Another thing that can be causing your problem is a monitor that is unable to put out the same brightness level as it did when new. This will also strain and fatigue your eye possibly causing pain. All CRT monitors over time will gradually lose their ability to put out the same level of brightness and a CRTs life is not that long...maybe 2 or 3 years. It may be time to assess your monitors brightness output and possibly consider replacing it with a new one.

Related to the previous is your working environment. Working in pitch black darkness, though good for reducing glare off the monitor and getting accurate color and tone, is not good for the eyes and can also strain them. A possible resolution for this would be to position a light/lamp in back of the monitor (if your monitor is not up against the wall) so that it's illuminating the area behind the monitor, but not pointing directly at your eyes. Also, you should sit about one to one and a half arm's length away from the screen

If you're doing lots of reading off of the monitor it may be wise to invest in a high quality LCD monitor for that task as LCDs are easier on the eyes and have no flicker to contend with. If like me, you insist on using a CRT, whether for performance or economic reasons, then certainly up your refresh rate to at least 85Hz, as has been mentioned before, so that flicker is greatly reduced. Reducing your resolution was also a good move as it will up the print and image size making life easier for your eyes.

Now, get lots of rest, drink lots of water, take two Aspirin, and call me in the morning. :) Hope this helped.

I have a similar problem, but my monitor is an LCD. I changed over to LCD because I thought it might be the CRT 'flicker', but the problem still occurs when I spend significant periods of time looking at the monitor (usually just before submission time for challenges).

I have this problem with my sony high brightness 'x-black' lcd screen too. I keep the brightness on the low setting when its not necessary.

Some tips:

1. keep your room lighting up higher rather than lower.
2. i know its tempting but dont spend too long looking at the screen. Maybe 20-30 mins at a time? Take regular breaks or do something non- computer based. (im no expert so check this stuff officially somewhere else)
3. get your eyes checked regularly

Hope this helps.
