AOC U2790VQ 27" 4K 3840x2160 UHD Frameless Monitor, IPS, 5ms, 1 Billion+ Colors, 108% sRGB, VESA, Black

If you’re in the hunt for a low-cost 4K monitor, this should definitely hit your radar. I’m loving its 350 nits brightness, especially when watching video feeds. It’s a vast improvement over my previous 250 nit 4K monitor. The extra nits allow for greater contrast and deeper blacks. Performance-wise, it’s a good monitor. The settings menu system is a bit funky, but nothing a person with a bit of sense can’t deal with. The manual isn’t of much help, only stating the obvious. Once you’ve figured things out and made your selections, most of what you’ll need will be controlled by the joystick power switch on the back, which is simple. Many AOC monitors have Philips counterparts that are internally identical. In the case of the AOC U2790VQ, the counterpart is the Philips 276E8VJSB. Besides costing less, the Philips also comes with a 4 year advance replacement warranty, though I have no idea how well Philips stands behind it. Why did I buy the AOC rather than the Philips? For health reasons I need a monitor whose height can be adjusted. Neither the AOC nor the Philips comes with a height-adjustable stand. The AOC has a VESA mount, though—and the Philips does not. It's a snap to replace the stand that comes with the AOC with a good, solid, inexpensive VESA stand. The base-hinged stands that come with these monitors aren’t nearly as firm. Also, the cables are hidden better with the AOC than with the Philips. But that's a quibble. Note: you could get the Philips 278E1A, which is virtually identical in specs to the 276E8VJSB and includes a VESA mount...but it’s been impossible to buy without also incurring a $40–50 shipping fee. So it turns out not to be less expensive than the AOC. So if you don't need a VESA mount or a really solid stand, go for the Philips monitor. If the stand is an issue, like it was for me, it only takes another $50 or so to fix you up.

Okay, so I bought this a while back as a second monitor. I do photography and videography, but only need to deliver in sRGB for the internet, so the 100% sRGB appealed to me (I managed to get to 99.8% of the sRGB gamut with DisplayCal). Surprisingly, though, I learned that I was getting nearly 89% of the AdobeRGB and 91% of the DCI-P3 gamuts when calibrated and verified. These are very good numbers, ones that even an LG 27UN850-W monitor costing almost twice as much doesn't even come close to. This is a good choice as a monitor for office work, imaging and viewing films. What I most like about this monitor is the unobtrusive anti-reflective coating, the lack of blooming of white on black text and the very reliable color accuracy. I don't game with it because I'm a responsible adult with a wide range of other time-sucking hobbies, but I'm sure with the meager refresh rate, it's not going to satisfy any hardcore gamers. But what I need it for, for doing some (non-critical) color-correct viewing, it meets and surpasses my expectations. The only downside for that is some inconsistency in the brightness uniformity. But this is absolutely forgivable for my purposes and I hardly even notice it. However, the brightness uniformity issue some have written about here leads to my next point about build quality. Here there are some issues. I suspect the uniformity issue is an issue of inconsistent quality control, because mine is tolerable and not as bad as some of the other examples seen here. Also, quality control was no doubt at issue when my monitor started developing vertical black lines after one year. This is caused by the adhesive degrading and the electrical inputs that connect to the display losing contact. I called AOC about it, I was asked to provide a few pictures and then I sent the monitor back. Thankfully, there's a generously long three-year warranty period on it. Because of the price I paid for it, I wasn't about to complain about losing it for three weeks, having to pay my own shipping and providing my own box, which they didn't send back to me. I was just happy to get a completely new one in an acceptable time-frame. Looking at the monitor and comparing it to other displays, such as my partner's MacBook Pro with the Retina display or the aforementioned piece of junk from LG, made me realize what a great buy this is. AOC is sacrificing a bit with build quality to provide some high capabilities in terms of what you buy the monitor for anyways: viewing. And with how fast display technology is moving, who really cares if the thing fails on you after three years? tl;dr buy this thing for literally anything else than gaming

If you're reading this and you have a full frame camera, just buy it. Your pictures are way more thank 4k and there's no point getting a TN or VA panel. For this price, it is beyond worth it for you. I've only had this for two weeks so I can't say too much about longevity but the quality of this monitor is great. The thin bezels are nice and slick, haven't had any dead pixels, the brightness is uncomfortably good so I tuned it down a bit, the menu is a bit wonky but it's AOC so I expected it, and the colours are just astounding. Again, if you're a photographer looking for a monitor and don't want to slap the money down on a BenQ, look no further. Just buy it already.

Excellent picture quality. No dead pixels. I use for photo editing and this monitor produce good color. I was deciding between 27" IPS or 32" VA monitors. I am very happy with the monitor. No color shifting with IPS.

Great for gaming and what I primaraly use it for ( photo editing) would buy again.

Way better than I expected. Great for working graphic design stuff.

Monitor is completely broken and felt very cheap. The HDMI/Display ports didnt line up with the body and it honestly doesn't look very nice in person. Will be going with something else.
