What are you guys' thoughts on this IPS display from AOC? http://www.anandtech.com/show/6468/aocs-i2367fh-thin-virtually-borderless-and-ips

It's on Amazon for $189. I love the look of it, but I'm wondering if it'd be better just to get the Asus IPS display for around the same price that everyone mostly has high praise for.

That AOC display is from AOC (they have a reputation for pretty much dumping things on the market) and they apparently lied about the viewing size (read your article again). I wouldn't trust it until TFTcentral had its way with it - I know that will never happen, and that paints me as a bit irrational, but so be it.

Also if you know anything about the U2412M, you'd know that 6-bit isn't the dealbreaker it used to be.

Yeah I'd just go with the Asus or the Dell.

I don't think the 6-bit IPS is going to short any desktop user on color depth who isn't a professional-grade artist or publisher, because really - who else needs to be that anal about their rainbow spectrum? The U2412m appeals to me from the tftcentral review because it was found to have some of the best blacks and lowest input lag in the entire class, not to mention possessing one of the greatest strengths of IPS design (viewing angles).

Says it's their "Monitor Sale of the Week" so probably just a meaningless arbitrary distinction between the national sites. Either way, it makes me glad I missed ordering one for $269 a week or two ago in this thread. I don't forsee the price dropping below this point for quite some time without, say, an actual coupon from Dell.

The rainbow spectrum isn't the issue since 6-bits should be more than enough to cover most of the tiny little sRGB spectrum. Luminance banding is. You're right - it's 100% irrelevant when watching movies or playing games (I can't notice and color IS my specialization) but when specifically working with colors it's an absolute nightmare.

Even if the FRC is good as soon as you do some calibration the internal processing causes a shitload of information loss which simply have no work around. Specially in the dark tones.

That's what I expected. What is the deleterious effect of luminance banding mostly, chunky gradients where they need to blend with perfect accuracy? How does calibrating for accuracy cause more information loss than standard? How do negative effects manifest in darker tones?

I'm not going to have a problem with any of this for my purposes, I'm simply legitimately interested.

Huh, it's the first time I see someone curious about that. I don't think even my students cared for that much.

Anyway, here's the :words::

It's very unlikely you'll be able to calibrate your monitor directly on a hardware level. If the monitor doesn't have a good LUT there'll be multiple pixel colors rounding up or down to the same value. Sometimes more. These occur outside the whole FRC thing, so if you're sensitive to temporal FRC that's an issue on top of it. FRC is not a problem per se when well-implemented.

And yes, luminance banding occurs as chunky gradients. It's really annoying, for example, when designing game alpha sprites with gradients. If they ever stack with each other for some reason you'll get gigantic blocks of color instead of a gradient. Do you have additive particles? That 0+0 becomes 0, the 1+1 becomes 2, the 2+2 becomes 4, 3+3 becomes 6. Suddenly you start having half the information because we're dealing with hard integers, and they represent big steps.

When you do a lot of work in grayscale these dark colors become somewhat important. Consider how grayscale only has 8 bits of accurate representation (a little over 9 with dithering). You know how people like to throw around arbitrary numbers like "the human eye can't distinguish any more than 10 million colors"?

Most of these assumptions date all the way back to a 50's book. A great, fantastic book, with some few outdated information. The thing about these 10 million colors is out of place, because the entire book is filled with mathematics, experiments, evidence, and that number is just thrown around. Back in college we argued about what it meant since people make serious research up to this day around these values treating them like they're some sort of gospel.

These 10 million colors could refer to chromacity, but most people assume they refer to our absolute perception of color. Here's the thing - the human eye is really good at adapting, so while it is that if you show a screen with all colors of the spectrum 10m would be a reasonable cap, that perception is wildly stretched because of our capacity to adapt to light intensity. Some researches estimate that we have the capacity to identify up to 1700 luminance levels being displayed simultaneously (if the light is too intense, the darker areas will become pure black). That's a little short of 2^11. Without dithering, we're talking about a 1080p screen showing a pure black-to-white gradient filling almost all of the horizontal space with no repeating pixels.

Backwards maths then indicate we can identify around 6000 chromas. Personally, I think that's bullcrap, but what this means is that while in theory a 24-bits total HSL system could faithfully represent all our static visual range, a 24-bits RGB system cannot. The theory behind that (that we need more bits for luminance than chromacity) is what gave us many functional video and image compression systems, by the way.

This is also why DCR exists, in theory (since in practice it sucks). When you're in pitch black and your eye adapts perfectly to the dark and you're facing a monitor with a decent contrast ratio, suddenly a gradient from 0,0,0 to 24,24,24 is trying to cover most of the 1700 luminance steps - except it doesn't. While that's an extreme and unrealistic situation, you can see how 256 undithered steps can be less than ideal. In theory, you'd need much more than 1700 to cover all the dynamic range possibilities, hence why HDR (64-96 bit images) exists at all.

In pratice, all of this means one thing when developing: Lots of banding, a crapload more banding, terrible ways to deal with dark tones since they're being stretched to accommodate the new gamma, and if you have bad FRC you also get to have some banding on a macro scale (from 4 to 4 steps). With a 6-bit processing, any calibration reduces your precision in the dark tones, so all of a sudden the double of 0,1,2,3 might become 0,2,2,6. With bad TN panels, that's not even a hyperbole.

Edit: I'm also surprised more people in this thread don't talk about the Hazro HZ27WC. I grabbed one for myself last year for around 400 dollars on sale, and it's been amazing. TFTcentral claims its about the same screen quality as the Apple/Dell 27inch displays, for literally less than half the price.

drat, that's complicated. I think I sort of get it, in that the basic color spectrum is representable by standard panels but what they're unable to reproduce effectively without distortion or inaccuracy are all those colors at all possible brightness levels within its range. Transparent gradients having to "round down" to the extent layering them then results in what amounts to a child mixing pixel colors like fingerpaint is quite drastic, in what medium do you usually see that display error occur when it does?

I want to use it a lot for Blu-rays and gaming, hooking up my computer (Games / Bluray) and my Xbox, both by HDMI.

There's not a huge amount to choose between them, but the 2711 is the better monitor, same with 2410 vs 2412, the older is better due to corner cutting to provide a more attractive price point.

As for the AG coating, in my opinion you have to be a real whiner to care about it. I think it's great at keeping glare to an absolute minimum. (I don't have U2711, only a U2410 and a 2007WFP).

1080p at 27" is going to look noticeably worse than at 24". I would try to find a 1080p 27" and see if you like it before pulling the trigger.

1920*1080 allows you to see more in gaming and view 16/9 movies without black bars, is worse for everything else. Other than that the panels seem pretty similar spec-wise:

The common thing I see cited for 1920x1200 is that you can fit a 1920x1080 frame 1:1 for editing and whatnot, assuming that the taskbar + UI of your editor can squeeze into 120 vertical pixels.

Really it comes down to personal preference. And the U2412 deleted anything outside of VGA/DP/DVI compared to its predecessor, so you get the same inputs no matter what.

Not sure about other games, but Diablo 3 always gives the same vertical field of view, so a 16:9 monitor will show more to the left and right than a 16:10. I noticed this when I switched from a lovely 1080p TN monitor to a u3011.

You can't have it locked in all three axis. If you lock it in both x and y, then the game screen will always look distorted unless you play on a 1:1 ratio.

Games usually lock it vertically so 16:9 returns a horizontal ratio bigger than 16:10. Some games are smarter about it and try to prevent extreme horizontal FoV by scaling it around a certain ratio, but usually it's around 16:9.
