    • Migrated from a TN monitor and WOW!
Size: 27 inch Style: QHD Curved 240Hz
VISUALS: I “upgraded” to this monitor due to some panel problems with my Pixio Px276. TN panels are known to be “dull” or not have the best colour accuracy so I expected this VA panel to provide a big visual difference and I wasn’t disappointed. The blacks are very dark and not as grey as they appeared on my previous monitor. I am currently playing through FFXVI and wow, is it a visual spectacle on this monitor! When testing on dark games primarily like FF7 remake the contrast caused the other colours to really pop on the screen. The colours are more vibrant than my previous TN panel and creates a much more visually appealing display. CURVE: Initially I was concerned with the 1000R curvature but this turned out to be a non issue after a couple days of usage. I am not sure if it was necessary for a 27” monitor as I do still find myself turning my head slightly when trying to focus on content at the furthest edge of the screen but I sit about two and a half feet away from it so it may not be an issue if you are closer. I have found that the curve does provide a more immersive experience when gaming or watching a movie. FRAMERATE: I don’t play competitive games so the 240HZ of this monitor is a bit overkill for my needs plus I don’t really have the GPU power to run newer titles at that frame rate. I did however try some older titles like Borderlands 2 to experience these high frame rates and they are buttery smooth although I personally can’t really seem to tell the difference between the 100s and 200s range. HDR: Unfortunately HDR is not supported on Ubuntu yet but I did try to test it on a Windows 10 machine and was left a bit perplexed. Now, I had heard that HDR wasn’t great on PC/Windows but I did not expect to have giant pixilated blocks with HDR enabled. I understand that some fine tuning is required to get HDR to work properly but I did not bother to pursue it as HDR wasn’t really a requirement for me but more of a bonus feature of the monitor. NEGATIVES: The only negative is that I found the menus to be a bit cumbersome to navigate at least when compared to my previous Pixio monitor. In my opinion the “normal” colour mode appeared to be more accurate than the default “warm” selection but I have barely made any changes to the monitor, using it with mostly default out of the box settings. I know there is an app that can be installed instead of fiddling with the monitor controls but I haven’t tested it. CONCLUSION: The monitor has worked great with no dead pixels etc over the last couple months of usage and do I hope it continues to last with no issues. I have known AOC to be a good legacy brand at least from the CRT days and I hope that legacy has been upheld over the years so that it has the same type of longevity and reliability as those older monitors. I think it’s a great monitor and from my personal experience it serves as a big upgrade in visual fidelity over a TN panel. ... show more

    • Sometimes things are inexplicably good.
Size: 31.5 Inch Style: QHD Flat VA 240Hz
A friend of mine suggested I check out AOC monitors when I was looking to upgrade from small, old 1080p relics. These monitors are HUGE. They are SLEEK. They are BRIGHT (but my eyes have not melted, there's settings on here). I have no issues gaming or reading documents. No dead pixels, no beefy price point. Just quality. I scratch my head at the price tag on "premium" monitors when this company has obviously got a fantastic product at a fair price already. Save yourself a headache and try AOC! ... show more

    • Great monitor - Recommend!
Size: 27 inch Style: QHD Curved 300Hz
Awesome. One of the best monitors I have had. Fits well on my desk, and it improved the graphics and colors on my games drastically. Not to mention, easy to put together and it’s sturdy. Have nothing bad to say about the monitor.

    • Best value of all 32 inch monitors? Possibly.
Size: 32 inch Style: QHD Curved 180Hz
The Good: Great contrast and color. You can play with the settings to make it really pop without touching your graphics card settings. It seems they solved VA black smearing in this cheap model? If there is, I don't see any. I usually test this driving around at night in Cyberpunk 2077 or looking at the stars in No Mans Sky. Even at low FPS (60-70) there is no black smearing but there is more motion blur. At high FPS (120+) it looks absolutely perfect to my eyes. I'm running a 9800x3d + 9070XT and it can push lots of FPS. Gets decently bright too. I had to lower brightness because it was straining my eyes. No dead pixels. VESA mountable. I don't think you can do better for the price. The Bad: HDR is broken. You will not get it to look good no matter what you try. Windows HDR calibrator, monitor settings and graphics card settings will not be enough to fix what is broken. My advice is forget its even an option. SDR is perfectly fine. The stand it comes with is garbage. Get a VESA arm or mount. Other Thoughts: My experience with AOC monitors is hit and miss. Some last 10 years and some last 10 weeks. I'm really happy with this one so I hope it sticks around. Other monitors tried and returned: HP OMEN 32q (mediocre) Samsung Odyssey G50d (beyond terrible). For the money you will not get a better 32. ... show more

    • After using for almost quite a full year, and forgot to write a review many months ago...
Size: 27 inch Style: QHD Curved 180Hz
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
