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

I have a 2 monitor set up that I use and switch between my personal and work computers. My other monitor has a KVM, so that makes it super convenient. Anyway, about this monitor. I was skeptical of this monitor at first because it is a VA panel. Turns out the picture quality is great. If there are any pixels burnt out, I couldn’t tell you as they are too small for me to see. This is my first curved monitor, and I have to say, I think I personally prefer curved monitors now. Especially whenever monitors start going above 27”. It just makes everything easier to see, for me. I’ve watched 4k videos/movies on this monitor and it’s flawless, with vibrant colors. I didn’t need anything super fancy or expensive for my secondary monitor, just something that works. 60Hz suits my needs. I did a lot of research between the VA panels and the IPS panels. The IPS monitors cost a lot more money, and for my primary use, which is office productivity, this is fine. If your primary use case is gaming or something with high accuracy color reproduction, then you might want to look at other monitors. I’ve played WoW on this monitor, and it worked fine, but I prefer my other monitor, which was made for gaming and higher FPS. After a year of owning this one, I am very pleased with it. Update: I have an M1 Mac Mini and running dark mode causes this screen to flicker, quite a lot. I have to run it in light mode, which I'm not a fan of, but this is not a problem of this monitor. The M1 Mac Mini, for some reason, doesn't support dark mode when running through HDMI. I haven't tried running this through USBC, so that may solve the issue, as I stated in my earlier review, this is my secondary monitor. I just wanted to provide that update in case you happen to have an M1 Mac, I can't speak to models other than the Mini, that you may experience this issue and it is your computer, not the monitor. My rating does not change as this monitor continues to be a great purchase.

I bought this at the end of 2019 as a gift for myself. I wanted a monitor that would be good for gaming and illustrations. Here's a run down of my specific wants: > 27" monitor (I felt 32" was too large. I would be fine with a 24", but this was, again, a gift for myself and I quite liked this size in comparison) > LED + IPS monitor > 4K Ultra HD resolution > High brightness > High color gamut > Low response time > High refresh rate > Anti-glare/Matte > VESA mountable If you've looked into this monitor some more, you will notice that it does not satisfy everything I wanted. The U2790VQ is NOT a LED monitor, but an LCD with WLED backlight, which is better than an LCD monitor without an LED backlight. It also does not have a high refresh rate; it caps at 60 fps (tested and true). But when put side by side to other 27" monitors with similar specs at this price, the U2790VQ was still the best option. This monitor has the highest brightness of 350 cd/m^2 compared to similar ones at this price point. There were others that had a higher refresh rate, but lower brightness and color gamut. Since I planned to use my computer for illustrations, the refresh rate wasn't as important of a factor as the brightness and color gamut. There were more expensive ones that could satisfy EVERYTHING I wanted, but I would be looking at, at minimum, a $150 increase in price, which I wasn't willing to shell out for. So, that is to say, I was willing to exchange these two points for the savings. -------------------------- I am back after a year just to see if the market has anything that might fit my wants better at the $200-$300 price point, but it seems that it is still the best option. I practically use it everyday for long periods of time, especially since COVID began, and it has not failed me in any regard. There is no bleeding, no dead cells, nothing. It's as good as it was right out of the box. I don't have to use it at full brightness--especially in the room I have it in--but it is nice to have that option. The screen is not AS consistent in color at different angles as I would like, but it is minimal and is only a slight nuisance when doing my illustrations. It is far better than a normal LCD monitor. Sometimes I do wish for higher fps, but I'm used to playing at lower fps rates anyhow, so it isn't something that bothers me--just a thing I would be looking for when I eventually upgrade to a monitor worth more than $500. I will be sticking with this one until then.

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.

I definitely like the picture quality. I bought it for editing in Lightroom, Photoshop and some video work in Premier. The colors seem pretty accurate. There is definitely more detail than the Dell Ultrasharp 24 it replaced. It's clearly got more definition. Based on my first 2 days of ownership, I'd say this is a great monitor at a good price. The only negatives are that it just feels and looks a bit cheaply made overall. The menu is operated with a tiny joystick on the back. The menus look extremely simplistic. The bezel feels like cheap plastic... it's not 'bad' it's just not "well made" like the Dell it replaced. I've read a lot of comments here that the monitor was great for up to a year then it started having problems.. I'm hoping that doesn't happen.. but for a sub-300 monitor that looks this good, I think there has to be compromises... and longevity might be one of them. But, we'll see. I've had it 2 days and so far I'm very happy. Everything is crisp and the colors look amazing. I'm still amazed at the detail.

Great monitor for the price. Purchased a few years ago, heavily used and still working great. Good color and sharp 4k with no dead pixels.

Prior to my purchase and subsequent disappointment, I read through all of the reviews for this monitor, especially those reviews where customers received defective AOC monitors, but my desperation to find a reasonably priced 4K monitor that was favorably reviewed on YouTube got the best of me and I placed my order. Essentially my understanding after my research was that this was a great monitor display because it was 4K with so so build quality but for the price. FYI, it appears that the price increased from last year (not supply and demand related) and it seems as though quality decreased. So I rolled the dice and placed an order for an AOC U2790VQ 27" 4K 3840x2160 UHD Frameless Monitor which took longer than promoted by Amazon (5 days and not 3 days). Unfortunately, upon receipt, right out of the box the monitor did not function. The monitor turned on but it would not recognize any of my computers (PC and Macs each running with different OS versions) with different types of cable connections and ports (Display Port "DP", HDMI to HDMI, DP to DP, Mini DP to DP, etc.). This particular AOC monitor had 2 HDMI ports and 1 DP, and yes, I connected to all of the ports with no success. So I called the manufacturer and I explained the issue I was having with the monitor where I was immediately informed that the unit was defective. I returned the unit same morning which was required for working at home and now I am searching for another monitor in a pinch where most monitors in this price range and specs are sold out. There was not any damage to the box and I watched the UPS driver gently place the boxed monitor right inside my front door. Of course, who knows what happened during transit by the shipper. The monitor was well packed, assembly was very simple and easy, shipped with no owner's manual (a download online from manufacturer website) but for a very small diagram paper quick assembly start manual that was included, a QC chart stating that all the pixels were tested and working for the serial number of my particular unit, a sheet of paper regarding warranty and manufacturer information, one HDMI to HDMI cable and one DP to DP cable. Although new and shiny, it was obvious that the build quality of the unit was suspect but at least you could look forward to a great screen to view at 4K which you could tilt about 5 +/- degrees if only and only if you happened to receive a functioning unit.

My AOC 27" 4K monitors are great. Color quality and brightness are meet my needs for general computer use (I do not do much graphics, video, or picture editing and no gaming). In fact, I've not made any adjustments to the picture settings. I do a lot of work in Excel and Word and the detail provided by 4K is amazing. Gridlines and numbers in Excel and fonts in Word are amazingly fine and crisp. It really improves using both apps. I'm also a high school volleyball coach and watch a lot of game videos which likewise are greatly improved in 4K (I use a GoPro 7 Black for filming). I bought the monitors to replace two 24" Dell monitors from work when I retired in January. I run them off a new Dell XPS 13" through a CalDigit Thunderbolt 3 dock with one running off the HDMI port and one off the Display Port. I do not use the included stands, other than for setting up the initial connection to the dock, but the stands were very easy to connect and disconnect to the monitors and I kept them in case I ever change my configuration. I do recall that the monitor position on the stands was rather low, maybe only 6" above the desk surface. Each of my monitors is mounted on a separate Huanuo articulated monitor arm attached to the back of my desk. I knew the 27" monitors were not going to fit inside the side supports of the hutch of my desk which is only 46.5" wide on the inside, so I have them positioned in front of the hutch with the center of the screens approximately at eye level. With the Huanuo arms, it's easy to move them down or to the side when needed to access the hutch or to bring one forward for close work. My only disappointment is that the side bezels are .3", not quite as thin as I was expecting from the "Frameless" heading and looking at the pictures online. In my arrangement there's about .62" space between active screen segments when perfectly aligned next to each other. Currently, I never have windows that span both screens, but I do plan to use this setup for Microsoft Flight Simulator someday and I had hoped for a slightly more seamless main display. If you're not familiar with AOC, the company is a direct descendent of the old Admiral TV and appliance company. When I was growing up in the 60s, many people had Admiral color TVs when color was first appearing. When I realized this I was more confident in giving these monitors a try and I've been completely satisfied with them.

I love this monitor. Purchased around two years ago and it’s still working great. The large size is wonderful for working from home, graphic design, and photo/video editing. I love editing in Lightroom on this monitor. The color and detail are great. I’ve truly had no issues. Set up is a breeze. Functions perfectly. Image is clear, clean, crisp. It’s not heavy but doesn’t fall over. Height adjusts easily. No issues connecting to my desktop or my husband’s work laptop. Price was great too!! Truly no complaints here.
