According to our monitor expert
Play your favorite games with sharp images with the AOC Q27G4ZR 27-inch 4K gaming monitor. Thanks to the 4K resolution, you can see every detail of your game. The landscapes and characters look lifelike. This monitor also has a 240Hz refresh rate, so you can quickly and sharply see every opponent. The 0.03ms response time ensures less screen tearing and motion blur. The AG276UZD also has an OLED panel. This means you can enjoy color differences between light and dark colors more. Because the shadows and dark spaces in your game are really dark, your game is even more realistic. Have an AMD or NVIDIA video card? G Sync adjusts the fps of your video card to the refresh rate of your monitor. This way, you're less bothered by screen tearing during fast movements.
Note: the maximum refresh rate via HDMI is 144Hz. Connect the monitor via DisplayPort for 240Hz gaming.

This monitor really surprised me and feels great when I set it up. I expected it to be recognized immediately, and it was. It's easy to adjust the height, and in my case, it was eventually installed on a monitor arm. I've been using this monitor with my Mac for a while now, and overall, I'm quite happy with it. The monitor should be able to handle 160Hz at 4K, but on my Mac, it's stuck at 144Hz. I think that's due to macOS. If you switch to Full HD, you should get 320Hz, but my Mac only manages 240Hz. I personally prefer 4K, so I prefer that setting. And let's be honest: if you're coming from 60Hz, 144Hz is already a significant improvement.
The monitor has thin bezels and looks sleek on my desk. The screen is easily height-adjustable, and connecting it is simple, as you only need one power cable without an extra adapter block. The monitor doesn't have built-in speakers, which is a shame. My previous monitor did have that, and I used it often. Now I have to use external speakers. Luckily, it does have a 3.5mm jack.
What's less convenient is the USB hub. You have to use two cables: one for power (USB-A to USB-A, which you don't see often anymore) and one for data (USB-B, also a bit outdated). The speed is fine for small files or things like a security key, but transferring large files is a bit slow. USB-C would actually have been a much better choice here. A clever feature: you can neatly tuck USB dongles behind the monitor, but it can sometimes take a bit of fiddling around finding the right one.
In short: this is a very good monitor for the price, especially if you use a Mac. The picture is great, it works smoothly, and it looks great on your desk.

This replaces a 10-year-old monitor. Technology hasn't stood still in that time. And now, mounted on a swivel tripod, it's absolutely perfect.
