Headaches/slight nausea from new monitor (1440p, glossy)?

post #1 of 9
Thread Starter 
Hi all,

This is a bit of a strange one, but after doing some googling, it doesn't seem like it's completely uncommon.

Over the weekend I bought the Auria EQ276W from Microcenter: http://www.microcenter.com/single_product_results.phtml?product_id=0384780

Overall, it looks to be a very nice monitor, good colors, etc etc. However, over the last few days, I notice that if I use it for more than an hour or two at a time, or try to play games on it, I have been getting headaches, sore eyes, and occasionally slight nausea. I want to use this monitor a lot over the next couple weeks while I'm still in my return period, but these symptoms are making it very difficult.

I'm thinking it's either the glare, the increased size of the monitor (went from a 22" to a 27") or maybe even the brightness, as I was running it higher, around 60-80, while I usually run monitors closer to 50%. It could also be the small text size while on the internet--getting used to zooming in web pages when necessary.

Anyone else in a similar situation? For some background, I also had headaches when I got my first LCD monitor in 2005, for about a month. I eventually got used to it, though. I now use LCD monitors through my work monitor, home monitor(s) and 1080p TV with nearly zero issues, yet this monitor has gone ahead and made them crop back up. I'm having trouble remembering if I had the nausea issues, or if that could be due to the immersive 27" size. I've been trying to play Fallout 3/Alan Wake's American Nightmare, which have camera movements that could potentially trigger my motion sickness. For the record, it's very rare I get motion sick from a game. Half-Life 2 did it after long play sessions, though.

Your problem might have to do with Pulse Width Modulation (PWM), which is the affordable technique LCD manufacturers have come up with to manage brightness control. What it essentially does is blink the backlight very fast in order to simulate more or less brightness. If you want more brightness, it will blink at more prolonged intervals, if you want less brightness it will blink at less prolonged intervals.

The added problem with LED backlit LCDs is the fact that when they are switched off they lose all luminance, whereas the CCFL lamp in CCFL backlit monitors has a phosphor coating that retains some luminance when it's turned off, so the strobing effect is much less pronounced.

In any case, the higher quality monitors use higher switching frequencies to mitigate this and some use capacitors in the circuitry, so LED backlit monitors mimick CCFL monitors in that the capacitor keeps feeding the LEDs in a fading manner until they are lit up again by the PWM circuitry.

You can check how bad the PWM is on your monitor by pointing a digital camera or a phone at it (in photo mode, preferably sport mode, which is more sensitive) and gradually reduce the brightness, you'll eventually start seeing flickering, the more, the worse it is. I had the same problem with a 27" LG E2770V-BF, so I went back to my CCFL backlit 20" LG L204WT, which, while having flickering, it is much less pronounced to the point my phone camera can't catch it even in sport mode (another more sensitive camera can), while it can catch the LG E2770V-BF flickering even in normal mode.

If you look at Dell's monitor range you'll notice that the expensive models use CCFL backlight, the U2410 is CCFL backlit, while the more affordable U2412M is LED backlit.

Wow...haven't ever looked into any of that terminology. I'm not seeing the flicker too much on my cameras, but they're also terrible cameras. Will play around with things and do some more research into PWM.

Thanks!

That's pretty much entirely unrelated.

The U2412M uses a cheaper display as well as cheaper technology. The U2410 is also marketed towards photo/color professionals as it produces extremely accurate color reproduction, but sucks at just about everything else.

Pretty much anyone will tell you to get the U2412 as it's better than the U2410 at everything but professional color work.

You're welcome! From now on don't forget to always inspect in the store the monitor you intend to buy.

How is it unrelated ? If the U2412M uses cheaper technology, you're proving my point.

Just because CCFL helps produce more accurate colors, doesn't mean the fact that it retains luminance while being switched off with PWM, wasn't one of the factors for them to decide in favour of using CCFL backlighting, given that professional level monitors tend to have characteristics that allow you to work many hours without eye strain. They could have opted for a high quality LED backlight, but they didn't. Maybe it would have been way more expensive to get the same color reproduction and high frequency PWM switching. On the other hand, they could have used CCFL backlighting in the U2412M, but they didn't.

And where did you get the idea that the U2410 sucks at everything else ? Don't forget that it uses an H-IPS panel, so it will never be as fast as a 120 Hz TN panel, and probably not as fast as an e-IPS panel, but what it compromises in speed it makes up in the quality of the panel, but that goes for most H-IPS panels anyway.

The 2412M uses technology that's less expensive to make and use, which is why the monitor is less expensive.

I'd like to know what features the U2410 has over the U2412 that reduce eye strain, other than the fact that one is CCFL and one is LED. If you have eye strain from a monitor, it's either from being too bright, having cool colors, or flickering light. The first two can be adjusted and the third is more prone to happen in cheap monitors.

You just listed off what I said for the reasons the U2410 is bad at everything else. It's not as fast as it's cheaper counterpart, it uses less energy, and it's worse for general use than a U2412. Any person who owns a U2410 will tell you not to get it unless you need the color reproduction and to go with another monitor instead.

Honestly, I don't think this is something I would have caught in-store. I did take a good look at it, and I didn't have any issues in store. Tough to gauge eye fatigue when it takes ~20 minutes of using the monitor for it to start happening. I also am sensitive to bright lights, the sun, etc...too much time indoors methinks tongue.gif

I still have 3 weeks to return it too, and last night I actually found some light bleed and a decent amount of dead pixels, too. Neither of which seems noticeable during normal use, but is still another reason to return.

Man, I'm trying to do that PWM test from the link in the second post, and having no luck whatsoever. I never see the lines they talk about. Either I'm doing it wrong, or it's possible my display doesn't have PWM? Can't imagine that since the Korean displays do, and this shares a lot of their traits.
