AOCAGON Gaming AG271QG - 27 Inch QHD Monitor, 165Hz,1 ms, IPS, G-Sync, AMD FreeSync, USB Hub, Height adjust, Speakers (2560x1440@ 165Hz, 350 cd/m², HDMI/DP/USB 3.0)

Pros:1440p screen resolution - increased screen real estate is very nice and helped me be more pdoductive on the desktop easier, gaming at 1440p is very crisp and beautiful, movies at 1440p is awesome too. Its native so no need for virtual super resolution from your amd driver or DSR from Nvidia drivers. Native 1440p works in Windows without a problem in scaling and Linux as well.144hz refresh rate- this is seriously a life changer. Gaming may feel a bit easier for competitive games, feel more immersive, boot may feel a margin faster with a fast ssd because the monitor displays faster , windows will respond better, etc. Everything feels faster, more responsive and smoother. While you could go for 1080p 144hz or 240hz, 1440p is the better deal for a few years at this point.Even though I can't quite game at 1440p 144hz, 1080p still looks okay for gaming, and even lower resolutions are fine. Worth having on my Ryzen 5 1600 + rx580 setup. 1ms response time is very low and basically almost removes ghosting so input lag and ghosting definitely not an issue. If you got games that run at above 144fps, this is worth having, even if its not 1440p. The resolution scaler on this monitor is superb even at relatively low resolutions that some gamers use if playing competitively like using a 4:3 stretch in CS:GO or if a game caps out at 1080p and doesn't go further in resolutions/ 1600x1200 4:3 in older games. Useful in speedrunning and perhaps world record challenges as well with higher refresh rates.Freesync, adaptive sync - This is useful in basically removing screen tearing, more accuracy of better frametimes, and the monitor syncs better basically. Freesync is only on AMD. However Nvidia had recently added Gsync compatible support on their drivers so Nvidia GPUs can recieve the benefit of adaptive sync technology, to have the same benefits as freesync but as Gsync. Hence why i chose this monitor in case i end up going Nvidia GPU in future, like a gtx 1080ti , rtx series card, etc. It was also certified for gsync compatible by Nvidia so its even better. In any case, its very nice to have. Freesync works in Windows and Linux as well.LFC, low framerate compensation also helps , when frames go low , so that the experience is more bearable.Better on eyes- since the monitor doesn't really flicker, it has been better for my eyes and using 144hz can be a bit easier on eyes on fast paced scenes than 60hz in some places. So i can have longer sessions using this monitor before taking a break without issues. Blue light filter helps as well to help me get to sleep easier after use. LFC, freesync to remove tearing between 30-144hz, height adjustment, tilt, swivel, rotate. All these options are a win. Very ergonomic to have the height adjust options for sure, not including if you decide to use a different vesa mount.Usb Hub- Its quite cool to have these extra usb ports. My monitor functions like a charging hub for my phones using a usb 3.0 cable, usb flash drives , controllers, usb microphone like blow snowball, and basically any usb device. 4 extra usb ports is always good and it helps with limited usb i/o on motherboard.Headphone stand - just there. I use it to rest my headphones.Comes with displayport , hdmi cables, dvi, usb monitor osd controls, monitor usb hub connection (to power the monitor usb ports). Also a vesa mount if you want a different stand to vesa mount on. Convenient, as expected of a premium to pay.Cons:Not that many really.TN- that may be a con to some for displaying accurate colours and higher bit depth colours. For gaming, its adequate enough and vibrant , definitely feels more vibrant and responsive than a cheap IPS monitor, but this wouldnt be ideal for creating graphics vs an IPS monitor at this price range. A lower hz IPS monitor or even a VA panel may be better for that.OSD- on screen display, its not the most intuitive to use , but it works alright. Feels average. Luckily they do have a joypad that you can use to connect by usb and navigate the monitor osd instead of clicking the buttons on the monitor.Overall great monitor for the price range. 24 inches is fine for me but if you want 27 inch, you can. I could have went for a 240hz monitor but this monitor was such a deal for me, and i wanted native 1440p.

Executive summary: Very good monitor, perfect for gaming, great colours and good angles. The only drawback of this one is anti-glare coating - which makes bright (white) pictures grainy - good thing is that you can get used to this.I bought this monitor because it was the only one featuring 24" size and 1440p/144hz picture. Most of the gaming screens are 27" but for me it is too much so I decided to take this premium AOC Agon screen and I don't regret it.Things I like:- Crisp picture- No glow - I can play long with 100% brightness and my eyes don't hurt- Superb external controller for quick changes of modes- Good stand- Premium build quality - better than dell for sure- Good colours - I'm comparing it with Dell H2515 which stands next to it.- FreeSync - which gives me smooth gameplay in most of modern games (I have AMD RX480 graphics card)- It is much easier to see enemies hiding in the shadow areas in CS:GO - Instant rank up :)- Very good downscaling - you don't notice that game is downscaled when you play in 1080p. It is not like on my Dell H2515 where picture is blurred and fonts are looking bad.- Great positioning of USB ports and inputs you don't have to go under the screen in order to plug HDMI cable or USB stick in.- A lot of useless cables :) This screen comes with every possible type of cable which is very rare but good.Things I don't like:- Grainy white surfaces because of anti-glare layer - I got used to it but it was annoying at first.- You need to have screwdriver in order to assemble it :) It is minor issue but keep it in mind when ordering.Edit: after 2 months of usage I can say that this monitor is very good - I absolutely love it! I have changed my rate from 4 to 5.

Very good monitor for the price that it comes at. Very good for less demanding games were I can get 1440p 144hz. But obviously not ideal for low end computers.PositivesGood controlsLots of optionsSee high quality detail with 1440p.Lots of screen relistate.Very high stand build quality and adjustability.NegativesCertain amount of back glow.Can be so bright that it hurts my eyes.
