New Monitors eye strain is it the LED or IPS?

post #1 of 15
Thread Starter 
I got new monitors, my previous monitors are Samsung 23" TN panel with no LED backlight

My new Monitors are 23" LG IPS with LED backlight. Both have the same resolution

AFter a couple days my eyes are strained and things look a bit blurry on the screen. And the screen looks like it has this haze that's coming out underneath everything. When I first got it I was amazed at how awesome it looked, the brightness and the colors. But now I seem to hate it.

I've turned the brightness alll the way down, the contrast all the down, even the blue color all the way down, but it still just isn't right.

Is this likely either a matter of the LED backlighting or is it IPS glow? I'm getting rid of these screens but now I'm not sure which feature I should avoid. I hooked my old screen back up again and it's soothing. The colors aren't as great as the IPS, but it's nice and calm on the eyes.

What do you guys think? worriedsmiley.gif

That's possible, LEDS can be concentrated and powerful, not sure how this translates through a monitor though. I've only owned one LED monitor and had no issues with it. Does it happen to be a glossy monitor rather than matte? If so that's the problem.

I have an HP IPS Panel (ZR24W) and havent noticed that issue with it. IPS panels are generally a little brighter I find.

Are you using your computer in the dark or have a bright light above or behind where you sit?

Im in my 40s and over the last year my eyes have started to struggle and now I need glasses for computer work. Can you still read a book with fairly small writing (paperback) without losing your focus? Thats what I noticed having an issue with first. Suddenly started to have to hold printed documents further and further away.

Get your eyes checked out just in case?

Had eyes checked a few months ago, everything is good.

I would suspect the other things except everything else is the same. The view distance, etc. And eyes were fine before the new monitors. And they are fine now that I am back on my old Samsung.

Not sure if they might be semi gloss, I'm not sure what that looks like. There is definitely a matte finish, but there was a slight glare in the screen that I don't have with the Samsung at all. But I also had a glossy TN non LED laptop before that didn't bother me even though the glare on that was really bad.

Could it be pwm flicker or some form of overdrive?

I would seriously recommend setting up Bias Lighting, regardless of the monitor you are using. I can't NOT use bias lighting anymore, and I have it set up with my monitors, my 47" LG LED LCD TV in family room, 55" LG LED LCD HDTV in bedroom, 70" RGB-LED back lit LCD TV with full local dimming in basement, and also behind the projector screen (grey) in my home theater.

It doesn't just reduce eyestrain, it also increases the perceived contrast ratio and makes everything look more saturatedwwithout becoming over saturated. The difference has to be seen to be believed. It's something where at first you are just like "that's neat", but after a few weeks if you watch the screen without it, everything looks dull and boring.

The key is getting a proper light with the right color temperature according to the color of the walls that will be reflecting the light. I suggest trying to stay as close to natural light as possible, and 6500K WG-CCFL lights give the absolute best results for me. I tried LEDs, but they are too focused, with a harsh cutoff compared to the soft glow of the CCFL's.

Thanks for all the tips guys. I had tried Flux, I always found it useful at times, but with those monitors while it did dim them down, the problem remained.

I will definitely update and improve my Bias lighting to 6500K WG-CCFL's. Thanks very much nleksan biggrin.gif

In the meantime though, if anyone had to guess which the cause was, would you guess the LED backlight or the IPS? I plan to get new screens soon and am on the fence now since most screens seem to have LED.

DiscoEST, you think it might be a PWM thing? I didn't see any flicker, but I don't really know anything about that stuff.
