    • Excellent condition, color and speed
Size: 27" 240Hz OLED
Received the monitor a couple days ago in great condition with no issues. Set it up and it worked perfectly with no dead pixel. No driver download needed. I used Windows 11's built in color tuning and text sharpening features in the settings to adjust the contrast brightness in gamma on the monitor to my liking. I'm really not noticing what some of the reviews say about fuzzy text. Windows 11 immediately recognize the resolution and 240 hz. The onboard manual controls for the monitor are fairly easy to understand and navigate. I was able to read the manual instructions which helped out a lot figuring out the settings on the monitor. Monitor comes with the USB cable power cable and an independent HDMI and DisplayPort cable. The stand is super easy to put together it's basically two pieces, one that pops into the back of the Monitor and one that pops into the feet of the stand. The monitor itself once put together is completely adjustable with varying height and tilt and angle and you can also flip the screen 90 degrees if you want to. Playing games like Fallout 4 or World of Tanks everything is buttery smooth and the colors are vibrant and bright with deep blacks. Every 4 hours of continuous use, it will prompt you to do a maintenance refresh on the monitor, that you can accept or deny. It performs automatically for you and I believe you can shut that off in the settings but I haven't bothered. So far I'm very impressed and excited and happy with my purchase. ... show more

    • Great Monitor for the Price
Size: 27" 240Hz OLED
This is a very nice monitor compared to other similarly priced monitors. The refresh rate and pixel response times are awesome as you would expect from an OLED monitor. For the money, I would say this is the best OLED monitor. The only downside would be that the screen is very shiny looking which causes bad reflections on the screen. My pc setup is in a room with windows and even after closing the blinds I can still see my reflection and the room around me. At nighttime I have no issues though, so make sure you have some good blinds and curtains and this is a great monitor for the price. ... 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.

    • Buyer beware of receiving used/returned junk
Size: 27" 240Hz OLED
Honestly, this monitor is nice and I dont have any beef with it. the problem is, when you buy a $500 monitor, you expect it to be new. Well, this was def used. I first suspected it when there was a sticker on the upper left hand corner directly on the screen. When I pulled it off, it left the residue and NOT easy to clean off. Of course, after the return period was over, I happened to notice an inch and half scratch in the lower right corner that I hadnt noticed before. I am NOT happy about receiving returned junk when I CLEARLY paid NEW price. now I am concerned this monitor is going to have a less than expected life. Examine THOROUGHLY when you open and return immediately if you suspect this same scenario. ... 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

    • Good value so far, weirdly tight vesa mounting screw.

I’ve only had the AOC Q27G4ZD a couple of days now, but so far so good. I appreciate the Pixel Refresh feature. I haven’t messed with any of the settings, everything is set to the defaults. Great image quality, the colors pop, etc. The only knock against it so far is that one of the screws for the vesa mounting points was waaay too tight, and now the head is stripped. But otherwise this seems like a great value OLED monitor. ... 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

    • 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
