Hi,
I've recently bought the HP ZR24W, a since-discontinued e-IPS (H2-IPS) 24" screen, which was highly praised in its price category in numerous reviews. The screen is great, the colors are great, basically everything's great about the screen, but since I've switched to it (from an old 19" BenQ FP91G+ that died a few months back), my eyes have begun hurting regularly during and even after working on the screen.
I spend a lot of time in front of the PC (on average, about 3-4 hours a day since I also use a notebook when at school, but when I'm home all day I can do as much as 8 hours on the screen). Now, I know that's a lot, but I haven't changed those habits significantly over the past several years, and I've never had a problem with my eyes until I got the ZR24W.
I ran the BenQ at 10% brightness all the time, and never had a problem. I lowered the ZR24W to 0 brightness, 70 contrast, sRGB 6500K setting (also tried custom RGB: 40-50-40 setting - not much different), which someone said corresponds to the minimum luminance he could measure on the screen, about 110 cd/m2. Now, I looked through forums, and I realize 110 minimum is quite a lot. I don't know how much my old BenQ had at 10% brightness, but I'm betting a lot less.
What I want to ask - is the reason the screen hurts my eyes this high brightness level, or could it be something else about it? I've heard people complaining of the "sparkly" finish these e-IPS panels seem to have, and some suggested that this finish is in fact the reason why the screen hurts the eyes. I do notice the sparkliness (like looking at tiny jewels set into the screen, very visible on white backgrounds) when I look closely. However, my eyes hurt also from gaming, even games with quite dark backgrounds (e.g. NFSU2 - takes place entirely at night). The sparkling, while presumably still present, is not evident there.
Finally, is there any way, like a firmware upgrade, that I could reduce the output of the CCFL tubes below the current 0 brightness? I'm thinking there isn't, but just to be sure... Mainly, I want to know if my problem is with the screen model (high brightness), or e-IPS technology (sparkliness), so that if I decide to switch (I know, it's a new screen, but the brightness is really unbearable, this way I'll be wearing glasses in half a year) I do not end up with the same problem. Any help is appreciated! Thanks
