    • Best Budget High-Refresh Monitor
Size: 27" 240Hz OLED
Easy to assemble and looks beautiful. The 200Hz refresh rate is a game-changer, and the colors really pop. The stand is standard with no adjustments, but that’s not a dealbreaker given the quality of the panel. I’m running my audio through external speakers, and the overall experience is fantastic. Highly recommended for anyone looking for a deal. ... show more

    • Great monitor
Size: 27" 240Hz OLED
Incredible color. Coming from TN panels I've always preferred response time and lackluster colors over color banding and input lag. OLED has both the best picture I've ever seen and the fastest response times. 240hz refresh rate for an OLED this price is about impossible to beat.

    • Came broken Came broken
Size: 27" 240Hz OLED
Review Image by Caroline
Colors are nice and screen is smooth, but text is a bit hard to read. The main problem is I waited over a month for this monitor and it came out of the box broken. Big black dead circle in the corner. The packaging was a bit crushed in that corner so maybe that’s why. Amazon won’t replace, only refund and it’s unavailable now. Extremely disappointed Update: Bought another one, used condition from Amazon warehouse. Received another dud that won't even turn on. The LED indicator flashes orange, which apparently indicates "OLED screen malfunction." It's a good price, but seems like AOC cut too many corners on QC. Won't be buying again ... show more

    • Absolutely Killer OLED Display Especially for the Cost
Size: 27" 240Hz OLED
For the cost of 2 of these, you can spend the same amount for 1 from other brands that would offer about the same in quality. Only real setbacks are the limited height adjustment with the provided stand and the very easy to scratch panel itself. Other than that, you're getting a great sweetspot sized 1440p monitor that's great for high FPS demanding games. ... show more

    • Good upgrade
Size: 27" 240Hz OLED
Never going back. Great OLED for the price. Haven’t had much of a problem with the purple-ish screen in the sunlight but don’t play in direct sunlight. Colors are rich and can be a bit bright but you can tone down the contrast and brightness on the monitor which fixed the issue. Prefer it to the WOLED and don’t regret it at all. ... show more

    • Awesome budget OLED
Size: 27" 240Hz OLED
Pros: QD OLED, image quality is 9/10 (as there are better OLED monitors, but compared to an IPS, its an 15/10), response time is exceptional, 10 times smoother than my previos LG 180 hz IPS. Cons: weird coil whine from the power supply, known issue in some forums. HDR has washed out colors but even without HDR the quality is fantastic. Recomended? Yes, without doubt. Would buy again? Yes. Gaming experience? 11/10 ... show more

    • Great Gaming Performance
Size: 27" 240Hz OLED
I’ve had this monitor for about a year and bought it mainly for high refresh rate gaming and fast response time. That was the main use case for me, and for that it’s been good. Gameplay feels smooth and responsive, and it was also very easy to set up right out of the box, which I appreciated. The biggest downside for me was the color. Out of the box, it didn’t look that great and definitely needed some tuning before I was happy with it. Once I adjusted it, it looked much better, but I do think that’s worth mentioning for anyone expecting it to look amazing immediately. One other thing I’ve noticed is that when I switch tabs or move between certain windows, the screen sometimes goes black for about half a second and then comes back. There’s a chance that could just be something on my end with my setup, cable, or settings, so I can’t say for sure that it’s the monitor itself, but it has been part of my experience. Overall, I still think it’s a good option for someone who wants to get into gaming monitors and wants high refresh rate performance without spending too much. It feels like a solid entry point if gaming smoothness and response time matter most to you, and you’re okay with doing a little picture adjustment. ... show more
