    Too Many Drawbacks

    Overall, I'd say this is definitely still an improvement from my 1080p IPS monitor. However, what at first feels like a premium product quickly gives way to limitations. Other reviews have already gone over the coloring situation for the most part. However, other reviewers claim that they simply had to lower their framerate to 170-179 to get the full dynamic 8bit range without dithering. This doesn't seem to be the case for me. My two choices seem to be 10-bit color at 120hz, and 8-bit with dithering at any refresh rate above that. I have not been able to disable dithering at any refresh rate above 120. After adjusting some other variables I've limited the color banding caused by this (which can occasionally be egregious on bright blue skies in games with HDR enabled), but be aware this is only a 120hz monitor if you plan on taking advantage of all of its features. I feel like displaying it as 180hz is almost false advertisement. I would've payed an extra $100 for a monitor that could run 10bit color at 180hz, and I would've been happy if I could've gotten rid of dithering above 120hz at the current price, but so far I haven't been able to. Haven't really noticed much (if any) black smearing or VRR flicker, but I'm not really a monitor snob. I'm overall happy with the picture, but I still regret my purchase. I wish I would've just saved my money and gone with an OLED instead, or at least a mini-led that provides full color. I'm not going to return it, but I imagine I'll be upgrading again within a year or so.

    Way Better Than Expected — A Hidden Gem!

    I wasn’t sure what to expect when I ordered this — there wasn’t much info out yet — but after a few days of use, I’m really impressed. The colors are close to IPS, and the blacks are surprisingly deep for a VA panel — about 80% of the way to OLED to my eyes. Even with full daylight coming into my room, the image holds up without looking washed out. Motion clarity is great too — I don’t notice any smearing or ghosting in games, and text looks sharp with no weird fringing like you sometimes see on OLED. VRR works fine — no flickering that I can see — and overall the monitor just feels good to use whether I’m gaming, browsing, or watching videos. For the price, it’s hard to beat. Definitely one of the best all-around 1440p monitors out there right now.

    $249 - $300 is a very good price for a MiniLED display that has 1152 zones. Monitor has less than ideal viewing angles due to its VA pane, but has great picture quality and contrast with decent motion performance and latency for a VA.

    Monitor can’t run at advertised 180hz without it limiting the color range. You have to create a custom resolution at 179hz to get the full color space. No speakers, no height adjustment. Horrible on screen display which locks a lot of options. No drivers, can’t update firmware. Vrr flickering, colors/hdr is good

    Bought when on sale for 250. Monitor looks amazing after tweaking osd settings. I like to keep my brightness down and not being able to use local dimming in the dark (because of how bright it gets and not being able to dim) is unfortunate. Other than that super solid. I was upgrading from a 60 Hz 1080p IPS so this is a huge improvement.

    When you put the local dimming higher, it makes smaller objects VERY dim (like the Youtube scroll bar on the bottom of a dark video for instance). Other than that, pretty good looking monitor. Color settings were a little red heavy out of the box, but was an easy fix.

    This monitor is awesome! Blacks are amazing on it, There is an issue trying to reach 180hz, you're limited to 170hz, unless you go to nvidia display panel, and do a custom resolution of 179 and other things. Its a firmware issue I think. I returned it because that.

    Good In An Age of Fantastic

    I am torn on this monitor. The blacks as advertised are pretty good, much better than your average IPS... The display is bright compared to an OLED. It's a lovely monitor... But there are issues. Sometimes I do see black smearing, particularly in scenes where there is a region of dark surrounded by light or light surrounded by dark. Sometimes small white objects like a mouse cursor will be dimmed to keep the blacks dark, which sort of ruins the illusion somewhat. I tried to plug in DisplayPort, but it kept flickering on and off. Looking online, it might be my graphics card not liking two DisplayPort outputs or it might be the monitor. HDMI works, but limits this monitor to 144 Hz. This monitor was supposed to tide me over until Black Friday (bought in prime day window) so I wouldn't miss my previous OLED that died tragically, but ultimately I bought another OLED soon afterward. This will become the Discord/other screen while the OLED becomes the Game/Video screen. I didn't return it because the sale window passed and it's pretty good when it behaves. I was trying to decide between a 4k monitor and this one for 50 bucks less, and I'd have chosen the 4k monitor if I could go back in time. However, I also have a 1080p monitor that it will replace that is super old (2014 vs 2025 time of review post). And again, the blacks are very nice. If I could give it 3.5 stars I would. However, when choosing between 4 and 3, I had to lean toward the negative because it's hard to put too much weight into the basics. It's a 1440p monitor... and you can buy one of those from 150 nowadays. It's 180 Hz if you can get DisplayPort to work... also 150. And the backlight is good... but when OLEDs keep falling down in price... It sort of feels like a half-step. It's a good monitor. It's just that we're in an age of 300 dollar 4k monitors and 400 dollar OLEDs during Prime Days or Black Fridays. A good monitor in an age of great monitors. 250 was the price I paid, and chances are that monitor prices keep going down. If only graphics cards would follow, one reason I chose this one was because a 4k monitor risks pushing modern graphics cards to an early grave nowadays...

    Great Montior; mediocre stand.

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Overall, this montior has been amazing compared to the one i used in the past. The Mini-LED panel absolutely blows away anything i had before, and has the added bonus of mimicing an OLED panel to an extent, even if the dimming zones can still be seen turning off and on with certain content. It also has a surprisingly wide range of features; although i havent actually gone through them fully myself. Turning on local dimming is a MUST on this! The only real complaint i have; even though its not a dealbreaker for me, is the stand and lack of ergonomic adjustments. Unlike my older montior, it cant swivel to a portrait mode and the stand is VERY limiting, only offering tilt adjustments. Otherwise, if you're looking for a relatively affordable (in its class) montior that has qualities similar to a far more expensive OLED, or if you're simply looking for something with great picture quality, then i'd recconmend this montior.

    I tried out a few monitors recently, but this is the one I am keeping. I haven't had any issues with VRR Flickering, black smearing or poor viewing angles. I did try the AOC Q27G3XMN for a couple of weeks, but returned it. This monitor feels like a definite upgrade. I am limiting my refresh rate to 120 hz so I can take advantage of the 10 bit RGB. I did color calibrate it, but it was pretty accurate out of the box.

    Screen looks great when its working properly but it is a major pain to setup for multiple tasks. If I wanted to use HDR in windows then i needed to use the picture HDR setting in the monitor menu because when windows hdr is selected makes everything look really washed out. However when opening a game and trying to play with HDR it doesnt work properly either, it required constantly flipping back and forth from the manual monitor HDR settings to the game HDR settings to make it look right. Local dimming can also be a factor in it looking right which adds even more things to mess around with constantly. If there were presets specifically for this that would be breat but I couldnt get it to work. I have a 5 year old TCL 4k TV that HDR just works as it should whether in windows or in games without any setting up needed at all. This is what i was hoping for but its just not there with this monitor. I ended up returning it.

    This is an excellent monitor for the price. The mini-LED and local dimming make for excellent contrast for games and movie streaming. The picture is also very sharp during general computer tasks as well. I also believe the colors are very accurate as well.

    Real HDR makes a big difference for a monitor in some situations. To get real HDR, and not washed out fake HDR, at this price is insane. On the negative side, the monitor stand, the ports, everything that isn’t the panel feels a bit cheap. It can also be tricky to configure the settings to fit your preferences. If you’re not tech savvy, it might be a real hassle to set up perfectly. Definitely do your research on the proper settings to get the most out of it. But, for $250 this is the best 1440p 27in monitor.

    Best budget HDR gaming monitor

    Good: - Doesn't look blurry in motion. - Mini-LED on a VA = better picture quality than most other non-OLEDs, and a good experience when viewing HDR content. - No dead-pixels on my unit or other signs of poor quality control. Bad: - 10-bit mode only works up to 120hz at 1440p which seems like a very unnecessary limitation. Overall: good value all-around monitor. This is the best budget 1440p monitor for singleplayer games. If all you play is competitive games, I would recommend something with a higher refresh-rate and/or an OLED. It would be very nice if AOC released a 240hz+ upgrade or a 32' 1440p version.

    Love this monitor, but a few complaints. Bought it on sale for around $220, which fits the monitor's size and features well. The picture is amazing, and the HDR is out of this world. It's blinding sometimes when you catch a sunrise over the horizon. It's not full 4K, but it is 1440, so higher than 1080P. For the size and price, I think the picture is magnificent. My biggest complaint is that it doesn't have speakers or too many input/output options.

    This monitor is absolutely perfect for high refresh rate 1440p gaming. The 180Hz panel makes everything look smooth, from fast-paced shooters to open-world games. The Mini-LED backlighting gives strong brightness and contrast, and the colors look sharp. For the price, this monitor delivers top-tier performance.
