I know this is a tough one to ask since there's no way anyone can actually look at my monitor in person and see if affects you, too, but my eyes have been really irritated the past 2-3 weeks.
 
Here's pertinent background info that you should know:
 
The monitor is only a couple years old (Samsung SyncMaster 2494), 23" inch LCD....I've been using it just fine with no eye issues up until 3 weeks or so ago when I had to swap out my old dying HDD and put in a new HDD. I had to reinstall everything including the drivers for graphics card etc. At first, the monitor setup didn't match so everything was out of proportion and it was blurry. When going to screen resolution, there was no option for my native resolution which is 1920x1080 ...so i had to go and download AMD Catalyst Control Center. My graphics card is AMD Radeon HD 6870.
 
From the control center I was able to tinker with some settings and finally found a way to use 1920x1080. It looked to be proper now just like before.
 
But for some reason my eyes started to feel strained and blurry and you know how you get those teary eyes when something is just not right? Maybe it's focus, maybe it's brightness, sharpness....but whatever it is, something most likely isn't right since my body is telling me that. My head says everything is proper. The settings on paper look to be exactly what they should be, but my body is telling me that something is not right which is why I'm getting blurry and teary eyes (I have to squint sometimes just to look at my screen). Now I don't wear glasses, but my vision is not as good seeing far away objects. I think that means I'm nearsighted right? Basically, I never have any problems looking at things that are close to me. So it's not something about my eyes suddenly going blind and needing glasses. I can look away from my monitor and read a book or look at a printed sheet of paper and everything is crystal clear with no straining or blurry vision. But when I glance back at my monitor, it's like I can't see sharply focused anymore...it makes me tear up.
 
I've tried adjusting both the settings on the computer and the settings on my monitor itself, but still my eyes feel very strained and vision is blurry that I have to squint. I NEVER had to do this before.
 
So I'm trusting my body instead of my head right now. Something is wrong with either my monitor or the computer settings and my screen must be on some incorrect setting that is hurting my eyes.
 
Can anyone help me troubleshoot? Can you suggest what I should take a look at it? If you need any answers from me, please ask me and I will try my best to answer.
 
I would like to get to the bottom of this and save my eyes. Right now it's even painful just to type this out cuz my eyes hurt like hell and I'm squinting and my eyes feel like they are constantly tearing up (like crying).
 
Thanks

No no, I can see just fine when I'm not looking at my monitor.  In fact, I can feel the difference right away as soon as I look away from my monitor, my eyes feel better already and I can feel the strain disappear immediately.  As soon as I look back at my monitor, the strain comes back.   

 

No eye doctor is required.  It's something to do with my monitor.  I actually plugged in a smaller LCD monitor right now (1600x900 native) and it's not bothering my eyes right now so I was right...there's something not properly set up with the 24" inch monitor and my computer because this smaller one is working fine.

You are sensitive to the light/brightness from the bigger monitor. That could be a problem with your eyes. 

 

Eliminate the possibility.

I've hooked up both monitors now as extended display so I can compare directly.  The problem isn't the brightness, contrast, or color or any of that.  What's bothering my eyes is the "text".  Pictures actually look exactly the same.  But the text is different.

The 21 inch lcd im using looks normal like the 24" used to be before I had to reinstall my OS and drivers.  The 24" LCD text looks a little fuzzy and choppy which is why I'm having the teary eyes when I'm trying to read them.  

 

I tried re-calibration, I tried cleartype, I've tried manually changing the screen resolution to something else and then back to native, but the text is still the same choppy/fuzzy look.  I have downloaded the drivers for my monitor (up to date)...I don't know what it could be.  

 

Once again, it's the text.  I can see it clearly now that I have it side by side that the text on the 24" inch is fuzzy.  One thing I did notice is that on my monitor settings, the option for "FINE" is NOT AVAILABLE it says.  I'm able to adjust everything else including sharpness, but none of that helped.  I'm wondering if the option for "FINE" is what I need to adjust but it won't allow me to.

 

Right now the 24" LCD is hooked up via HDMI cable since the 21" is using the DVI cable.

There are so many ways that a monitor can fail and cause all manner of eye strains.  Color changes and sync faults can give instant headaches and even induce epileptic seizures.  Another monitor would confirm that problem.  Normal eye sight away from that display means it might be a high flicker rate that the eyes can't handle.
