Matte means it scatters reflected light so anything in front of the screen such as you and what is behind you is not clearly reflected for you to see, on a glossy display you can see yourself the wall behind you etc. glossy is like a mirror.
Matte has a "dirtier" look and glossy looks cleaner with slightly better contrast. Matte also reflects a little light that hits it from wider angles, hence reduced contrast. And the surface looks more like paper than a clear glass.
Semi glossy, almost glossy is kind of the best, at least for me. With glossy all you do is try remove reflections in your room, or tilt your laptop glossy screen to various angles so it doesn't reflect ceiling lights, you get it.

I never use scaling and 1440p 31.5" is almost equal PPI to 1080p 23.5"/1200p 24". So you will likely have to use the same scaling you're used to from the 24" if you need scaling.

27" 4k 60Hz + adaptive sync, well the PPI definitely needs UI scaling in Windows even for me I think as 1440p 27" already can be a bit small. The monitor seems basic, otherwise I don't know, often specs can look enticing for monitors but the reality may differ a lot.
4k with a 1060 in modern games = R.I.P., it can do 1440p OK but 4k no chance and even on lowest settings it's going to struggle.

Okay Jack, thank you very much for all your help!

I will most probably buy it. Do you happen to know the dead pixel policy of this monitor? If I will buy it from Amazon UK, for example, will I be able to return it IF there will be dead pixels, even one, or if there will be any severe bleeding or anything else really annoying?

I would be willing to pay almost double to get a good, all purpose, monitor but if I do not have to, I will not. For me, good monitor means very nice colors and to play movies well. I do not play games, I am not a gamer. I might play a game once every 4 months and I never complete it. With my current HP ZR2440w I have been almost completely satisfied with it, when it comes to how it displays color.

One other thing is, will I be able to use this AOC with my laptop? Below are its Specs.




Thanks again.

In EU, so I suppose in UK still as well, you have 2 weeks by law to return a product no questions asked, well unless you are in the very east of EU where laws are more of a guidelines.
After that the usual pixel policy applies and those are often poor and allow certain number and size of defects. Almost no one but the few business oriented companies with their more professional business lines offers zero pixel defects for full warranty length.

I don't see why not, 1440p 75Hz I can run from HD4600 Intel iGPU. The monitor has DP, HDMI, DVI, VGA, AOC tends to add them all on their monitors, what ever connection you need it's gonna have it although 1440p 75Hz will probably only work on DP and HDMI, maybe DVI.
Adaptive sync with Nvidia is DP only because they don't support it over HDMI on anything.

Okay Jack, thanks again

From what I see, AOC permits up to one full pixel to be defect... Have you had any defect pixels?

In any case, I will order it after a few days! IF it will come with a dead pixel I will return it. I never had any display with dead pixels in my life.

What is the alternative you would suggest to me, in case something will go wrong with this AOC?

That's not too bad if it's class 1:



Acer is worse: https://www.acer.com/ac/en/IN/content/dead-pixel
Dell has 0 on bright but otherwise is worse: https://www.dell.com/support/article...elines?lang=en
etc.

I haven't noticed any defects yet. *knocks on wood*

There are not similar alternatives beside a Q3279VWF VA variant. A 1440p 75Hz with adaptive sync isn't common among monitor makers, most of these are 1440p 60Hz with maybe some having adaptive sync and using old panels of which I've seen horror photos on shops posted by users with crazy glow, BLB, these older panels weren't great.

If there was something similar I'm sure it would pop up on price comparison sites and shops as a top seller but I haven't seen anything. There was one Viewsonic -2k at it's code end: VX3276-2K-mhd, has no sync, no idea what panel if it's the same or similar, who knows, if I remember right it was expensive and has no adaptive sync. Most other are likely 60Hz no adaptive sync.
Philips could have a similar monitor but I haven't seen it yet, AOC and Philips are kind of siblings and children of TPV.

Encouraged by the opinions I bought this AOC. And... i return it immediately.

From bad things:
- I had 2 black "bad pixels" at the start :/ One in the center, second on the left. Very distracting...
- Sharp scratches on the back cover... rather, resulting from poor control at the factory. I could live it...
- There was same backlight bleed but not to much.
- IPS glow is strong!, very noticeable even in the light. Especially the lower left and upper corner. In games like new Tomb Raider it is very visible. Really, this is not a monitor for "dark" games.
- The viewing angles are very weak for IPS screen.

Good stuff:
- It actually has good colors even at factory settings.
- Good text sharpness. It does not strain your eyes.
- very low input lag
- overall good build quality with the exception of "scratches"

Have you bought it from Amazon UK?

Adaptive sync with Nvidia is DP only because they don't support it over HDMI on anything.

A dual-link DVI will support the resolution. I run my 1080p 144Hz on a DL-DVI and on an 8-bit panel, that's 7,166,361,600 bps (1920 * 1080 * 144 * 24). A 1440p 8-bit panel running at 75 Hz will need a bandwidth of 6,635,520,000 bps.
DL-DVI provides a bandwidth of almost 10Gbps (~7.9 after overhead).

All room lights off, monitor at 90% brightness, with white barely clipped and how it should look:



This is overexposed by changing ISO 100 to 800, you can see a bit of BLB on my unit's top edge above lamp on right side:



And this is the original image:



It's not easy to capture the IPS glow without overexposing a lot as I do for glow and BLB test photos of black image.
There is glow, there will always be on IPS without a glow reducing/removing filter but from my experience it's better than the AUO M270DAN2.x 27" in terms of glow and BLB. For how large 31.5" is I do not think the glow is too bright where as on AUO's 27" I found it quite bright and annoying especially for a 27".

If someone is going from a TN to IPS then sure they will find IPS glow weird and undesirable, rightfully so. But it's a better technology in almost every other respect.
VA has it's own quirks, you can choose that and deal with VA glow instead.

For now you can see my glow examples here: https://imgur.com/a/Sm96pse
While the photos are not perfectly comparable brightness wise, Samsung VA has much brighter glow than AUO VA on the panels shown and AUO IPS brighter than BOE IPS of this AOC. My old Z24i also had quite noticeable glow but I think it was oriented with the brighter yellow part of glow on top edge, making it more bearable, still for a 24" it wasn't that great glow wise.

If you want really low LCD glow you have to try the AUO VA in LG, Pixio, ... or just get OLED :/
You can't find monitors with the glow reducing filter anymore, they don't want to make the panels, maybe someone patented it and went away from the business. Only so few ever existed. They do exist for small panels though, on mobile devices, and cheap.

Thinking about giving this one a try after receiving my second Acer VG270UP with worse glow than the last one and a stuck pixel.

I really liked the VA variant of this monitor, but it had horrible smearing in some games. It wasn't even the 75hz that killed the fun, only the smearing pissed me off. That was a real deal breaker, sadly.
Not sure about the coating of this one, though. Seems bad compared to LG/Dell monitors and especially the VA variant of this AOC.

What do you think about the coating?
