AOC U2879VF 28-inch Ultra HD FreeSync Monitor Review

A 28-inch TN screen is the cheapest way to put Ultra HD on the desktop. Today, we're looking at a new example from AOC: the U2879VF. It includes FreeSync for gaming enthusiasts and a factory calibration for the professional user.

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Packaging, Physical Layout And Accessories

The U2879VF presents a slim chassis and stand so the packaging is equally efficient. The parts are well protected from shipping abuse nonetheless. Included cables are HDMI, VGA and DisplayPort. The power supply takes the form of a small brick.

The upright is already attached to the panel so all that's required for assembly is connecting the base with a captive bolt.

Product 360

The bezel measures a reasonably thin 17mm all around making the U2879VF a good candidate for multi-screen setups. Controls are via push-buttons arranged under the bezel. They're set back a bit and have to be operated by feel and they activate with a satisfying click. Tiny icons tell you their functions. The only other adornment in front is a small AOC logo.

The anti-glare layer resists reflection well while providing good image clarity and offering slightly better off-axis quality than many other Ultra HD TN monitors. Even though this is the same panel part we've seen on previous products, AOC has managed to mitigate the color and brightness shift somewhat. You can see what we mean in the photo on page seven.

From the side, one can see AOC's distinct minimalist style with a thin panel and all internals housed in a lower bulge. The upright grows from this bulge and offers only a tilt adjustment. Height and swivel are fixed. The stand provides plenty of security and feels like a quality piece.

The U2879VF is smooth across the back with a mixture of gloss and textured black plastic. There is no VESA mount here so you're stuck with AOC's stand as your only mounting option.

The rear-facing inputs are easy to see when you hook up sources. You get one each of DVI, HDMI 2.0, DisplayPort and VGA. The audio jack is a headphone output. At the far left is the power connector. On the extreme right edge of the photo is a Kensington lock.

    I've been using this monitor for month or so now, and I have to say, I'm very pleased with my purchase. I got it on sale though, so it was a bit cheaper.

    Please call me when these monitors are no longer only 60Hz. I still much prefer a 1440p monitor with 144Hz over 4k on 60Hz for gaming.

    I can I agree with that for the people with better eye sight its blurry if its 60Hz but not if its 144Hz or 120Hz.

    While I understand that 60 FPS may be the top for high end gaming rigs for this resolution - that is in some games, not all. I agree 2160 at 60Hz is, for me, a step back from 1440 at 120Hz+ since my rig can easily push higher FPS on many games I play regularly.

    I'm currently rocking 3 1440p monitors in Eyefinity and I love them for Gaming at 7680x1440p. They are 60hz panels, but I can OC'd them to 75hz. It's not easy getting 75fps at that res maxed out tho... 11.2 million pixels is no joke, but the FEEL of them wrapping around you is incredible & it's widely supported (hehe) by most games. I'd highly recommend anyone giving it a try. I've got some footage up on XBnPC if you all care to check it out.

    Well right now is not a video card that can be played at 100+fps on 4k with ultra settings, even the 1080 as good it's, not reach those frames on 4k of course and AAA games.
    The monitor is for the present 4k at 60hz even the prices it's good for the spec.
    The speed of hz and the resolution are two different things, of course you will get higher hz at lower resolution. In a near future it will be 4k with 120hz or 144hz, coz 4k will be standard for 5 years as 1080p and 1440 or qhd will just be a transitition as was 720p.

    *Freesync doesn't work well at 40 to 60Hz.

    You need 2.5X minimum ratio for asynchronous mode (i.e. 30 Hz to 75Hz) or you have no support below 40Hz.

    With the range being so low you are popping in and out of the smoother asynchronous mode any time you go above or below this. If it's setup for VSYNC ON you'll go from smooth gameplay to STUTTERING below 40FPS (or screen tear if setup for VSYNC OFF).

    Same goes for above 60FPS (though I think you can force a Global cap but you have to experiment with that and it may have to be a bit below 60FPS).

    *If you have a 30Hz to 144Hz it's far better. Not only is it hard to go over 144FPS, but for demanding games (or sudden drops even if good FPS) you CAN stay in asynchronous mode.

    The REASON is that AMD has no module like GSYNC does. So if you drop to 29FPS then the drivers tell the GPU to send each frame 2X so the monitor gets 58FPS. You still see it as 29FPS but a SMOOTH 29FPS because you stay in asynchronous mode so the monitor draws each frame as it gets it.

    There is a small DELAY in doing this so you can't get by with just 2X the range. So again, for the 40Hz to 60Hz range if you drop to 39FPS it doesn't work.

    **IMO they shouldn't even sell Freesync monitors like this. If you don't understand what's going on you're going to have an inconsistent experience with many games being smoother then stutter or tear constantly.

    Umm, ya? That's the underlying point of my entire post! To expand, I am not willing to spend money on a monitor that is "for now" ok, when I find the 1440 experience (on IPS panels) so good. Since I run 27 now, why go a minor increase for a 4K panel that won't look as good while gaming, i.e. low frame rates? And to get even more specific - I am team green so I wouldn't buy an FS monitor in the first place! :lol:

    I have an earlier version AOC U2870VQE 28" 4K LED Monitor I bought for roughly the same price.. I really like it. This was an upgrade from another brand 1440 monitor that was returned under warranty for too many dead pixels. This AOC has no bad pixels. Mostly play Total War games with 2x980sli. For reference my everyday overclocked Firestrike Ultra graphics score is around 6650 with max of around 7000. I generally play at high settings rather than ultra because I like to speed battles up 2 or 4 times speed during slower action periods to move them along quicker.
