It's as matte as matte can be. You can see it on solid bright colors that they are not clean but have that "broken" up look. It's not crystal matte as DELL loved to butcher their monitors with. But it's still fairly matte and not what I would call a semi matte or semi glossy.
I don't like blacks smearing and viewing angles on VA so I went with this one. For the money around 200 EUR... it's good considering those 144Hz panels and monitors at 2-4x cost are often worse in picture quality...

I have my gallery of pixel structure here for now if you want to compare: https://imgur.com/a/0ewvudg
The AOC pixel structure photo is in OP.

Cleanest most glossy like so far that I took a picture of is probably Z24i (old LG IPS) and 32GK850G (recent AUO VA). The Samsung VA and AUO IPS are probably behind that.

Personally I'm OK with matte but of course would prefer semi glossy/near glossy coating instead if possible, something probably that is on the VA variant although that one looks as if it's almost glossy (maybe too much glossy).
See the first photos of dark screen for comparison:

Then your only choice is to see the 32GK850G, C27HG70, XF270HUA close ups and compare to Q3279VWFD8 close up photo.
There is no cross hatching etc. but it's definitely miles "dirtier" looking than the near glossy VA variant.
This is most visible on bright sites such as OCN, I don't notice the matte much elsewhere, bright solid colors then one can see that it's matte.

And I do not think there is any easy fool proof way to go and rip the coating off. The frame is pressed together and getting into it means prying it open. I know people used to do this risky butchery on some old monitors to remove bad matte coatings, if it's even still possible on these newer panels.

Panda made the VA almost glossy, BOE makes this IPS with a matte coating, AOC might not even get a choice of coating. From BOE the panel is advertised 60Hz with semi set backlight, TPV takes it puts on a wider gamut backlight, adds electronics that drive it at 75Hz and sells it under AOC brand. Browsing Philips catalog is a nightmare and finding their monitor to buy almost the same, they could potentially offer something similar if they wanted to, another company under TPV.

Set range of the monitor in CRU to 36-76Hz. It will run 38-74fps synced + <38fps with LFC to at least as low as 1fps (tested now with RTSS limiting in a DX11 windowed fullscreen game, I can't see any tearing at low fps, may be different in exclusive fullscreen applications, many games run only windowed mode nowadays). No Vsync like stutters, no tearing. At near 0fps it may occasionally flicker, rare but can happen, probably no different than a Gsync monitor really when it comes to these inconsistencies.
There is no need to add FreeSync range in the extension block.

with 36-76 in cru (amd gpu) you dont get flickering?

i get heavy flickering in the range of ~35-38 in pendulum (full screen ticked) and in 1 game i tried (not the best game to try i guess... its The Council :p ) in borderless fullscreen, in just (exclusive) "fullscreen" freesync doesnt activate (dont know why, maybe game specific?).

please give as much info you have >.<

I tried it on GTX 1060. I can get it to activate by running a fullscreen adaptive synced application such as Pendulum demo and turning the monitor soft off/on while the application is running, this seems to be an issue on all units so far, there is a decent German list of Gsync compatibility reports from users made by a site: https://www.computerbase.de/forum/threads/nvidia-freesync-erfahrungen.1848940/ by I don't think many people figured it out yet that most monitors with issues can be made to work this way. This I think has to do with how GPU driver and Monitor activate/detect adaptive sync and on some monitors they fail to sync unless an adaptive sync output is coming from GPU and monitor detects that. I think it can be resolved by driver update, something that AMD has been doing probably but Nvidia did not since they did not support anything but their Gsync module.

Borderless mode is Windowed mode so you need to enable adaptive sync for fullscreen AND windowed mode. Then it seemed windowed fullscreen mode was adaptive synced to me on Nvidia. Still running windowed mode you often run the risk of having Vsync enforced in some situations especially without adaptive sync you pretty much may get Vsync all the time in that mode, it can depend on the game and GPU overrides for the game.

Are you sure it's exclusive fullscreen and not only windowed fullscreen? So many developers lately are a bit lazy and they only offer windowed modes. When you ALT+TAB out of game and into it does the screen blinks to black and the computer kind of "hangs" for a short time as it switches modes? If it does noticeably blink to black then that is likely exclusive fullscreen. If there is no delay and you're immediately on desktop then that is not exclusive fullscreen mode.

In GPU drivers for selection of adaptive sync:
fullscreen = exclusive fullscreen
windowed = windowed, windowed borderless, windowed fullscreen

Overall no has yet gotten this monitor to work flawlessly without doing the above off/on trick on Nvidia I think. And the sync that trick makes only lasts until monitor goes to sleep or monitor restarts in any way, probably PC restart will unsync it again, as long as you keep the monitor it will work but once the monitor changes modes, goodbye sync and I get back a previous frame duplication.

I've set range to 1-144Hz and tried to find where the limits on lower and upper range are, when does it start to flicker and when does it start to tear. 38-74fps worked for me and with upper limiter I can run 38-75Hz adaptive synced, above 75Hz will start to show a tear, 37 and below flickers, so Nvidia starts LFC at below 38 when I set range to 36-76Hz and I then have 1-75Hz synced issue free (well OD is not ideal it gets stronger and stronger toward 38Hz, it's not adaptive).

Well, I kind of accidentally ordered one. :p
196€, so it's worth taking a very minor, from what I gather, risk.

Please, write your impressions on this thread when you will receive it and spend a few days with it. Personally, I am not so much interested in games but I am interested in how well colors are displayed and how well it performs on movies.
@iakoboss7
Hello there, from what I gather you have the same screen? How well does it perform when watching a movie and how accurate + vivid its colors are, would you say?


PS: my experience and measure of comparison are the two monitors shown in my sig_rig, from both of which I am very satisfied. Both are matte, I think

Thank you, and @JackCY, thanks a lot man for your input on that Philips. I've read it on Amazon com, as well... Too bad their power supply is like that. One cannot replace that, right?

Very well, I will. My Dell U2412M will sit by its side for the sake of panel comparison.

thank you for the effort of answering!!!

as i said i am using an amd gpu (rx 480) so i do not have any of the problems nvidia users have.
amd's LFC also kicks in when i set it 36-76.

how is it issue free when you set it 36-76? cause i get heavy flickering in fullscreen pendulum somewhere in the range of 34-38.

also how did you overclock it higher than 75? when i set anything higher than "76" in cru it does not get recognized by "display property adapter" settings nor in amd driver settings.

I set it as per the attached picture, only changing that VRR range where the cursor is, look what is highlighted: Edit - Range limits - V rate.
For VRR range it doesn't care that I raise the upper limit too high, it does not go there at least not on Nvidia, it stays at 75Hz max. If I make a custom resolution (no sync) with anything above 76-76.5Hz it will report input out of range sort of thing on black screen. The monitor "protects" itself and blocks any OC, as all DP input monitors do really.

The lower range flickering may likely differ unit from unit, and combination of GPU + monitor. You're getting flickering at 34-38Hz while set at 36Hz minimum range? That's odd, 37Hz should turn to be 74Hz and I can see that from how overdrive artifact changes when LFC starts to double the refresh, Nvidia starts LFC on: below lower range +2Hz, AMD may have a different LFC activation point. You probably need LFC to kick in sooner but cannot get that because the monitor won't allow you VRR upper range above 76Hz probably at least not effectively tear free. Maybe AMD starts LFC at lower range without offset so you set 38-76Hz and it could work.

LP: If a power supply is built in as on most IPS monitors, then it's difficult to replace it with a different one. On many VA monitors with external power brick you could try find a different brick or DIY easily, or just hide the brick in some sound proof box LOL, but the buzz on 144Hz VA is not really coming from the power brick, Samsung's tend to make noise from the electronics itself inside monitor. Most monitors do in some situation. Even this AOC I think at very fine pixel pattern, it's because of inversion vs the pattern interaction. Inversion aren't randomized, they are patterned for simplicity so when you find the pattern all monitors tend to buzz a bit when you display some kind of fine pattern matching the inversion pattern. No LCD has 100% issue free inversion, this AOC is pretty good with it.

Q3279VWFD8: IPS, faster response times, better viewing angles, decent contrast good for an IPS, wider gamut and decent colors, matte
Q3279VWF: VA, slow smearing blacks response times, worse viewing angles, great contrast for an LCD monitor, sRGB and loss of saturation at angles due to viewing angles limitation, almost glossy

Nothing more to it. The IPS will have better colors and motion handling but with VA variant you get better contrast and coating.

Yes VA looks nice for movies/etc. but personally I find the smearing blacks and viewing angles causing loss of saturation undesirable.
I don't know what other IPS with similar specs there is unless you want to spend 8x as much for a 4k 60Hz professional monitor of same size, sure that one is likely better (uniformity, ... , though maybe not contrast wise or glow wise) and has hardware calibration and all that.
No LCD monitor is perfectly uniform and spending a lot doesn't grant you perfect uniformity either. For around 200 EUR this monitor isn't bad at all but there sure is some uniformity variation that you can see at times especially on lower brightness settings.

That's odd, 37Hz should turn to be 74Hz and I can see that from how overdrive artifact changes when LFC starts to double the refresh, Nvidia starts LFC on: below lower range +2Hz, AMD may have a different LFC activation point. You probably need LFC to kick in sooner but cannot get that because the monitor won't allow you VRR upper range above 76Hz probably at least not effectively tear free. Maybe AMD starts LFC at lower range without offset so you set 38-76Hz and it could work.

yep, thats how exactly i have set it, like in your picture.

actually flickering happens around 36-37 ( i checked it again) when set to 36-76. and around ~37 when set at 37-76.

in amd, to get lfc to work fully i have to set it to 36-76.
at 38-76 i get no lfc at all.
at 37-76 i get lfc to work on framerates below 32 and higher than 37 (5 hz gap) for some odd reason!

also when set at 38-76 freesync kicks in above 39, even at 38,8 i have tearing.

Yeah it's a driver thing, there is nothing more to LFC I think. It simply activates at different points on AMD. Plus the monitor is by default 48-76Hz VRR with no LFC advertised. Overall AMD and Nvidia "want" 2.4-2.6x lower range compared to upper range to "support" LFC. 60-144Hz for example. But technically it only needs to be 2.0x.

Problem is while the "protocol" is standardized each company has implemented it with different "behavior" of activation, plus Nvidia in general ignores standards when ever they want or deem desirable, "cheating" and taking advantage where ever they see it. If all the corporations were on board of adaptive sync from the get go and cooperated with monitor/scaler/input board makers the whole situation of poor performance of some monitors and GPU combinations would have been resolved long ago. Nvidia instead said screw it and made their own expensive FPGA input board with limited features that they sell to AUO and now maybe LG to be used with their panels rather than try and cooperate as this way they got more profit and lockdown of customers to their products.

Plus with HDMI2.1 coming with 7nm GPUs at least with Nvidia ones after Turing, they will have VRR. Their lockdown to Gsync was about to get removed by standardization sooner or later anyway. The premium for Gsync board with more limited features is too much, people pay more to get less... it's ridiculous.

Maybe there is some variation unit from unit but I would say the GPU driver plays a bigger role than that. You could run 40-75Hz working range with no LFC as if you're getting under 40fps you've got bigger problem than sync :D

Update: managed to overclock the upper freesync range to 76 (38-77), and by disabling "gpu scaling" and by using 8bit color depth instead from 10 (is there any difference?) i managed to make windows recognize the 76hz refresh rate.

so now by using 38-77 i have freesync range at the following fps:
39-76 and 20-32 (pendulum goes down only to 20). so now there is a strange gap where tearing happens and that is 33-38fps.

tried 37-77 but i get massive flickering at arround ~37 +-1

if only i could make it to run flicker free at 37-77 i would have full LFC :(((

any tips?

Set the lower range as low as possible so that it activates LFC for the first refresh that otherwise flickers. Raise upper range to what ever I think as it doesn't have an effect, at least not on Nvidia but if it does on AMD then your max is probably 76 (default) or 76.5-77, maybe 78 but it may crap out if it tries to run 76-78Hz adaptive synced, Nvidia doesn't it stays at 75Hz even if I set 80 or 144Hz upper range.

Was the same for me with having one refresh and tiny bit around it flicker, so you have to raise the minimum until it doesn't as LFC activates higher.

Nothing more you can do. I wouldn't sweat it not having LFC as it's more of a gimmick anyway, those ranges are not usable in gaming really and you can probably live with the occasional tear during some slow loading screen or 10 smoke grenades bogging down your GPU to low fps or something.

well (if i understood your suggestion) i tried 34-76 and 30-76.

34-76 seems the same as 36-76 (flickering but lfc is on)
30-76 has worse flickering than everything else. (and strangely at ~34-35 there was tearing lol). the strange thing is that the monitor flickers at around 35-38fps, it seriously had no problem at 20-34fps. thats super strange.

for now i reverted to the "Stable" config of 38-76 (with 39-75 freesync range).

i really dont understand how yours does not flicker and you are able to run 36-76. maybe i am unlucky :p

First impression - great picture.
IPS glow from ~55cm away is noticeable, but nothing out of the ordinary (I can see it on the 24" U2412M as well).
The default stand is really flimsy.
It also comes with a DP cable (not just the HDMI they list it with)!


Colours are great, I am very happy with what I see so far.
