i want to know if the led tecnology cause more difficoult to the eyes respect than a NOT LED monitor.

I have a little problem to my eyes, i'm most sensible to the light, and i searc a monitor that can to be used with a value around to 100cd/m^2 of brightness.

I thinked an Acer H243HX but there's any reviews by users ( only Digitalversus ) and any setting configuration profile on the web.

the alternative is the Samsung XL2370 but is LED, i want a 60Hz monitor not 3D, for play ( not slow monitor ) and good for reading, but i dont find any moddel.
 
I'd say LED is easier on your eyes I have a Samsung PX2370 and haven't had any eye strain issues, also if you Google "led vs. cfl eye strain" the results seem to agree. It's also a good model for gaming with only 3ms input lag vs. a CRT.

You might also like the Magiclux feature found on the PX2370 it automatically adjusts brightness depending on room lighting, it's main purpose is to reduce eye strain.

There's probably other models that meet your criteria but it's one to consider.

The XL2370 is an older model but also a lot brighter at around 344 cd/m2 max brightness so it might be to bright, it also doesnt have the magiclux sensor. The PX2370 maxes out around 240 cd/m2 brightness and can be adjusted around 100 cd/m2 , especially with the magiclux sensitivity set on High. (it has 3 settings).
 
I have an acer LED S231HL. I thought this monitor helped reduce eye strain. I adjusted the brightness down to about 50% but the colors (color corrected) were still vibrant.
 
My experience is the opposite: I've used monitors for 20 years, with long sessions and allnighters doing graphics / games / CAD and never had eye strain.

Then, after gettting a new LED Samsung P2270, within 2 weeks I had serious eye strain: in fact I had to completely minimize my computer time on any monitor, even wide screen TV's at the pub would effect me. Looking for 5 minutes was too much!

I went back to my old monitors, used eye drops, and eliminated surfing / online news for a while to get back into shape.

Now I do still use that monitor but it's not my main monitor.

I tested out a variety of settings in brightness / contrast to reduce the brightness.

The P2270 is not an LED model.
 
Is PX2370 very good with DVI input ? You use the MagicLux tecnology ?

i know that the reading text in this model is below averange.
This is true or a user fantasy ?

LED backlighting being easier on the eyes=user fantasy. The PX2370 is a rip off, there are a ton of better TN panels that don't cost 280$. I have owned and calibrated the PX2370 next to CCFL panels.

Eye strain is most likely caused by lighting conditions, using high brightness, monitor sharpness and Angrily Glare coating.

OP you were looking at the 2333t before right? Text will be much clearer due to the very mild AG coating=less aggressive than the PX2370, good default sharpness and high contrast. A glossy TN would be an even better choice for reading due to the extra clarity.
 
Flickering can produce eyestrain as everyone can recall from the CRT days. The way that mainstream LED backlights control the brightness is by pulse width modulation which varies how long the LED is on at maximum intensity. The dimmer you set the display, the longer the LED is pulsed off, and the more noticeable the flicker and thus eyestrain. So if anything, an LED backlit display at less than maximum brightness may increase eyestrain, and unfortunately at maximum brightness there tends to be some bleed since most are of the edge-lit design, so I would recommend against it.

NCX, sorry, but your absolute hatred for LG anti-glare coatings goes in DIRECT opposition to the suggestion from my optometrist that specifically asked to ensure that the monitors I was using had a very effective anti-glare screen or else I should invest in one, as reflections are a known cause of eyestrain. You don't like them, fine, but please don't assign false attributes to them.

I suffered severe eyestrain in 2009 resulting in blurred vision and issues refocusing on close to distant objects and visa versa despite previous perfect vision which was shortly after taking on my night shift job while also covering half the shift of another on maternity leave at the time, so 60hrs a week in a dark data center.

Repositioned desk fan, cup lights behind my monitors, and a few other simple exercises were recommended and did the trick. If in doubt, make an appointment to have your eyes checked and you should be given a questionnaire to fill out and small simple changes may be all that is needed or it could be something different entirely such as symptom of hypertension (caffeine + salty foods + overweight = fast food lifestyle hypertension recipe), but don't get your hopes up on LED backlights being of any help.

I used to think Glossy would be great until I bought an NEC 20WMGX2, It had nice picture quality but eye strain was a frequent complaint and ended up being one of the reasons I sold it and went back to CRT.

I can use this PX2370 for several hours a day without it bothering my eyes.
 
Who is better 24" TN for 250$ ?
I know that :

Samsung 2470H
Samsung FX2490
Acer H243HX

I wait the NCX raccomanded too
 
Just wanted to say that it may not be the monitor that is causing the eyestrain but psychological reasons. If you think the new LED technology may cause eye strain, then it probably will cause you eye strain.

You have to look at the fact that 99% of the people use these monitors all day without any problems.
 
It really does vary from person to person but with things like the Nintendo's 3-DS causing eye strain in Japan I'm happy this is getting more attention. Too bad SED never made it to market though that would of been great.
I tried a OLED screen it didn't work out ouch! I tried 5 different LCD but not a LED backlite one. I'll try one when I see one at Retail l(so I can return it) I just updated my computer this week from a 2003 AGP video card slot board to a XFX PCI-E Vga port card still using a CRT 19" trinitron monitor from 2001.

so I can play Rift =)

There's a big difference between an anti-reflective coating and a coating that is so harsh that you are forced to squint to read text on it.

Reading text on my old Samsung 226bw is easier than my zr24w simply because of the aggressive AG coating on the HP vs the not so aggressive anti-reflective coating on the Samsung.
 
i dunno about all you guys.. for me, my LED's i have tried are all harder on my eyes than LCD monitors.. i started a new thread on this and ill be posting side by side pics soon.
