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 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.

During my test period, I was immediately struck by the AOC U27G4R's versatility. With its 4K resolution and IPS technology, the screen delivers razor-sharp images with beautiful, natural colors. For everyday use, such as browsing the internet, watching TV shows, or working with Office applications, this monitor is more than adequate.
Gamers will also find it a great choice. The 144Hz refresh rate and Adaptive Sync ensure a smooth experience, even with fast-paced action games. The stand's build quality feels solid, and the monitor's height and angle are easily adjustable, which is convenient for long workdays. The modern ports (HDMI 2.1 and DisplayPort 1.4) are a big plus. All in all, a monitor that perfectly supports both work and play.
