    • Great value

Amazing monitor. Great value for money nothing beats it at that price. The interface menus is extremely easy to set up. It works better while connected to displayport using hdmi limits the hertz and brightness. Really crisp colors and the curve isn’t too much it’s just in the sweet spot.

    • After using for almost quite a full year, and forgot to write a review many months ago...
Size: 27 inch Style: QHD|180Hz|Gaming
The monitor is pretty good, but one has to remember it's a VA panel. There is some blacklight bleed as all VAs have, I've not had issue, as it varies panel to panel in production of such. This is the second AOC monitor I've owned in like... 25 years. This monitor is better than my old VA panel Viotech generic brand one which had got in 2018 and went to the digital grave when attempting to use G-Sync or something late 2024. It was also 27" sized screen like this one, but not as "strong" as the 1500R curve as this. This AOC monitor can do HDR if you want, but oh man that hurts my eyes sitting about an arm length away, so I don't. G-Sync/VRR also works on this, but remember this isn't an OLED/QD-LED so high frame rates and ghosting will happen, this is more for cinematic gaming/and browsing web/etc. Color is good, but not OLED/QD-OLED level. Documentation was kind of light, and they do expect you to download the monitor app for more in depth use and firmware updates. ... show more

    • Awesome monitor
Size: 27 inch Style: QHD|180Hz|Gaming
I needed a high resolution big monitor. I saw this one as a return. It was in excellent, new shape. It's a fantasic monitor. I didn't really buy it for the curved but I think it helps my vision. It really helps me complete my work better. Since it was a return the price was fantastic. I am using it with a suface tablet and it works perfectly. I really do like this monitor. ... show more

    • Very nice monitor
Size: 27 inch Style: QHD|180Hz|Gaming
Great montior Wonderful refresh rate and clarity. The stand is a little awkward in terms of its footprint, but im assuming its to best distribute the weight. Easy to setup and ability to raise/lower, turn and tilt. For this size of a curved QHD monitor, its a great deal

    • Awesome budget 1440p gaming monitor
Size: 27 inch Style: QHD|180Hz|Gaming
Arrived safely and works perfectly for gaming. HDR at 189hz through displayport is what I needed. Can't beat the price either.

    • Nice monitor, but hilariously crooked and unwieldy stand
Size: 27 inch Style: QHD|180Hz|Gaming
Review Image by Broyant
This review is for the CQ27G4H 2K 27" 1500R 180Hz curved gaming monitor. Paid about $199+tax for it around the time of Black Friday 2024. Full disclosure, was searching for a new monitor for both PS5 and PC gaming and was previously using a 1080p Vizio HDTV from like 2010. Any monitor nowadays would probably be an upgrade compared to that. Of what I tested, the visuals looked great for PS5 gaming. Supported 2K resolution with HDR at 120 Hz while playing supported games. No dead pixels or flickering; looked solid out of the box. Unfortunately, I stopped testing there and didn't attempt to max out the performance by plugging in my gaming PC... Because, the monitor stand was hilariously crooked to the point of being unplayable. Notice the levels on the stand legs, and on the top of the monitor - this picture wasn't taken at a weird angle, it's taken from the front! This is NOT the type of stand that features rotating the monitor to portrait mode, too - and the piece that goes into the monitor is hard fixed to the stand stem, so there's no adjusting it. (Checking Reddit and doing Google searches reveals that the monitor stand quality of AOC monitors can be very hit-or-miss.) The stand's base is also a very sharp-angled V as opposed to a regular rectangular or round island shape, which I imagine can definitely get in the way and take up a strange amount of space on your desk. My options for the crooked stand were to attempt to unscrew some of the screws on the plate to try to realign it (but didn't do that because I didn't want to risk voiding warranty), or to contact AOC customer service. Contacting AOC's customer service on their official website requires you to create an account, which is where I decided to throw in the towel and return the monitor. I had read a lot of customer service reviews with this company and seen many hit-or-miss stories too. I realize I also could have bought a third party 100x100 VESA mount stand, as this monitor does support that... But why should I have to immediately discard the stand that comes with the monitor and buy a replacement stand unless it were defective? This was my first time buying from this brand. Again, the monitor seemed fine for gaming, but the stand was very crooked and it wasn't worth the extra effort for me to come up with a solution so I could keep it. ... show more

I bought this monitor for my laptop so it would as a PC rather than just a laptop. I use it for both gaming and schoolwork and I absolutely love it. Fits perfectly on a standard dorm desk, the quality is amazing, and the product is great for what you pay for. The curve isn’t super bothersome either. 5/5 product. The only thing I have is that the stand itself is pretty bulky and heavy- but the monitor itself is fine. ... show more

    • Very pleased!
Size: 27 inch Style: QHD|180Hz|Gaming
I'm loving it! Massive upgrade from my old Z-display, bless it's heart- still kickin but pixels are slowly dying- This monitor? No dead pixels-arrived safe and well packaged. The high refresh rate is something totally foreign to me and I feel like i'm playing in butter, it's so smooth! The colors are rich, no screen tearing, the stand looked kinda cheap in the photos but is incredibly solid(not worried about the cat bumping into it) and easy to set up. my knowledge of monitors is rather limited but it does not seem to perform well capped at 60fps (in the one game i tested ff14) but setting it to main display refresh rate fixed that- I've only been updating my tech recently from dinosaur stuff XD, so in my experience having high fluctuating frames causes a lot of hitching but that doesn't happen here at all. Very pleased! ... show more
