Underrated solid monitor. If you’re looking to upgrade to an oled or 1440p I would buy this one. Great price for a 1440p 240hz oled. Amazing contrast, no fuzzy text unlike Woled. Nice set of settings. Comes with hdmi and display port cables, great fully adjustable stand etc. don’t waste your money on the same features for other brand names. And 4 year warranty if you’re worried. I bought it one sale for $400 which is honestly completely worth it for this monitor. I use it for pc and ps5, it’s the perfect monitor for ps5 does 1440p 120hz hdr gaming and 4k 60hz also hdr when on YouTube, Netflix etc. it switches between 4k and 1440p automatically so just leave it at 4k. No vrr but I don’t have any issues and no flicker so far. It also has speakers but they’re bare minimum if you don’t mind bad quality and just plain sound it’s a bonus. You get used to the sound so I’d say it’s a plus overall for budget gamers. For most people this would be the perfect monitor.

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!

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.

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.
