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.
