   I have two of these (27″ 4K) and one of the 43″ 4K models. All are incredible monitors. I’m a professional software developer and I spend 8+ hours a day reading text and needing to differentiate between slight color variations. I’ve owned multiple monitors from all the brands – Apple, LG, Samsung, Dell, Acer, etc.I purchased the 43″ cousin of this monitor in 2019 and have had zero issues so far (December 2021).This monitor technology is my absolute favorite and – for an unbeatable price. Highly recommend them!

   My prior setup was 4 x ASUS VS238H-P 23″ Full HD 1920×1080 monitors from 2013. They still work great but I wanted more resolution.I reviewed multiple monitors side by side. They were all from Amazon but were limited to supporting free returns, and non with inbuilt USB-C. One for example was a top report winner (LG 27UK650-W)My goal is for work purposes not gaming. I also do video conferencing and watch streaming video. I did compare all playing 4K high-res videos on 2 monitors and a Macbook screen concurrently. It was impressive with all monitors in sync. I found no out of bounds coloring, slow syncing or choppiness.In the end the savings of this monitor over other models let me purchase 3 instead of just 2 for my desk.I did not review any monitor with USB-C. The extra money was not IMO worth it. I did buy a j5create unit so I could run 3 4k monitors on my Macbook pro. With 3 monitors you must plug power into your laptop, you cannot daisy chain it, as it just cannot charge fast enough.It does help to calibrate your monitors.The stand for this monitor is it’s biggest fault. As I mount my monitors I just discarded that, but if you want to place on desk with the provided stand, not great.It takes a bit more than I wish in menu options to switch HDMI inputs on a monitor. I miss the easier multiple buttons of the single behind the screen one most monitors have.

   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.

   This monitor does not support 3840×2160 @ 60Hz as advertised! At 3840×2160, you can only do 30Hz.This means that you notice the mouse lag on the screen, and if you have a good eye and a mild case of OCD, it will drive you crazy!Aside from that, the display is gorgeous and the build quality seems solid.EDIT: As it turns out, my initial review shows ignorance on my part. My computer had an older HDMI port that didn’t support 4k @ 60Hz. I learned this after buying a more expensive LG monitor. The monitor is good. Changing to 5 stars.

   I had gone through several monitors for my flight sim/work/occasional photo editing setup, I started with an old 24″ 1080p IPS panel but trying to fly with only one monitor is no fun, it was ok for everything else. I scavenged 3 22″ 1080p TN panels that were ok for flying but no good for work or photo editing. I then purchased 3 24″ 1080 VA 144hz panels, the high refresh was nice but the color was worse than the TN panels. I returned those and purchased 3 of the 27″ 4k IPS AOC panels. Here’s the pros and consPros:-Excellent color compared to everything I’ve used previously-Amazing clarity on text and photos-No noticeable backlight bleed-Outstanding viewing angles-Minimal bezel looks great in multi monitor setup-Color calibration and uniformity certificate with each monitor, and the certified measurements are absolutely incredible at this price point, color average deltaE is 0.4 to 0.5 for the monitors I received and uniformity is almost perfect 100%, one of the monitors has 99% at one of the measurement locations, I know where it from the certificate but I cannot see any deviation in brightness with my eyes-3 inputs allows me to run my PC, Mac and laptop dock without an expensive triple monitor 4k kvm (I have a basic usb switch to take care of switching the keyboard and mouse)-Scales lower resolutions really well, 1080 and 1440 have minimal blurringCons:-One of the HDMI inputs is only 1.4 which maxes out at 4k 30hz-HDMI inputs are not labeled which is HDMI 2.0 and which is HDMI 1.4, also no mention of which is which in the manual (as of now I don’t know which is which as my Mac and laptop dock max out at 4k 30, my work ordered a Dell D6000 dock which will do 2 monitors at 4k 60 and the third at 4k 30. I’ll try to update this when I figure it out which port is which) – EDIT- HDMI 1 is 4k 60, HDMI 2 is 4k 30-The area around the inputs looks “cheap” the black plastic cover has some big gaps around the input area so you can see the metal inside and silver tape-Some ghosting or trailing due to slow pixel response times, really only noticeable when you move a white mouse pointer on a very dark backgroundNit picks:-Only 60hz, but you’re not going to find a high refresh 4k anywhere near this price point, you’re looking at almost 10x the price for 144hz, at least for now-Not Freesync or variable refresh, same as aboveNotes:-The panel is 10bit/pixel but I don’t think it accepts a 30bit color input, all of my computers indicate 24bit color with no option for 30bit. 24bit is good enough for me so I have not investigated it any furtherI am extremely satisfied with these monitors, great value for such an amazing display. At my office I have a different brand 4k monitor that was almost double the price of the AOC and honestly the AOC looks much better

   I am very happy with this purchase. I am a part time pro and upgraded from a lower resolution monitor. I post process everything and find this monitor to work well. My video card allows the full 4K resolution and it is fantastic. Are there better monitors out there for photography, of course but it is great for most with a little careful set up.Straight out of the box I changes the picture mode to Sports to get the brightness up to a proper level. I also changed the color temperature to cool and then used my video card software to slightly tweak the colors. Perfect.The packaging is excellent and everything is individually wrapped and got here perfectly. The joystick on the back to make all the adjustments is fantastic, and the build quality is great all the way around. I most heartily recommend this monitor for photography and general use. Copy and text is flawless and it is just about impossible to see the individual LED’s. It also comes with cables which is a great bonus.

   I’m an industrial design student. The colors on this monitor (calibrated with x-rite display pro plus) seem to be no different from my other monitor, which cost me a solid $800. Keep in mind that if you don’t have a screen calibration device, don’t expect to do any color-critical work on this monitor out of the box because the tint is too red and the color temp is too cold even though it did come with a chart in the packaging showing that it went through some sort of factory calibration. Maybe they calibrated this screen to 7500K in the factory but normally we don’t use 7500K for video or photo editing.However, you can’t blame AOC for the colors on this monitor because there are some big brands that do an even worse job when it comes to color accuracy. For example, the Wacom Cintiq Pro 24 I got earlier this year had very nasty greenish colors out of the box. It was 10 times less accurate than this monitor, and the Cintiq runs for $2,000.It does have a very advanced feature called border compensation. If you enable this option, the monitor will compensate for the dimming near the corners of the screen to ensure you see the same brightness across the entire screen. It’s really nice to have this feature because most monitors even the more advanced ones don’t have it.In conclusion, this monitor is a very solid 4k monitor. I don’t want to call it a budget monitor because there are some stereotypes associated with the word “budget.” It’s cheap but it’s by no means worse than the 2x or even 10x more expensive counterparts.A little tip:If you connect this monitor to a Mac using the DP port and install a software called “MonitorControl”, you can conveniently control the brightness of the monitor using the brightness adjustment keys on your keyboard. I don’t know if this feature is standard with the DisplayPort protocol but it seems to work on all my monitors. For PC users, maybe you can find some tweaks on GitHub that can do the same thing.

   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

   After getting this set up I can confidently say this is a great 4k monitor for the money!However, two important “gotchas” to note:1. HDMI Input 2 did not support 60hz at 4k… I had to use HDMI Input 12. Out of the box the colors were a bit messy and the blacks were too grayish.IMO, the following profile looks much better:Contrast 50Brightness 45Gamma 3Red 52Green 50Blue 52

    This is a review for the U2790VQ. These are selling like hotcakes during covid since everyone is working from home but if you wait patiently you will get one. This is probably not the best gaming monitor since it’s slow but for office productivity, light coding, it fits the bill. I’ve tried philips and LG but this one seems to fit the bill the best for the budget. I am using this with a macbook pro 2015 so the native resolution is 2560 x 1440 (QHD). The Default for this is 1920 x 1080 but if you want more real estate i would go larger. Though it can do 4k, I usually upscale so that the font and text is clearer. The OSD is kind of rudimentary, nothing as good as LGs or Philips but it works. There’s even some blue light filter modes that make it yellowish to save your eyes. The panel is made by Panda LM270PF1L which is found in the philips as well. It’s matte and 3H hardness so its pretty good glarewise. I have just powered it on for a bout a day but I will review in a months time for daily use. I may get a second to get more realestate and a dual monitor mount. display is pretty light, about 3kgs without the stand. The stand? Pretty crappy. I would say just throw it out. It’s all plastic and it wobbles on my sturdy desk. I understand why manuf. want to cut costs and they do it with the stand. It’s not even height adjustable. It tilts about 15′ only. Brightness is pretty good. No sound even though speaker grills are there. I think they use this shell for another model. It doesn’t matter anyway since most monitor speakers are pretty weak at 3W or even 5W. Just hook it up to something else since there’s a headphone jack.Bezel is pretty thin, I would say 5mm on all side, the bottom is the thickest. Maybe next time they can just make the AOC symbol light gray instead of silver. Back has 2 HDMI, 1 DP which is my suggested way to connect since it offers the best resolutions.If you can pick it up below $250s. It’s still worth it. I wish they had this exact one in 32″ but I guess that’s for the future. End of line.
