Whether you’re watching movies, playing games, or getting some work done, you’ll get amazing visuals with up to UHD1 resolution. Enjoy more monitor real estate with an up to 34” ZeroFrame display1, allowing you to see more and do more.

Vivid HDR

When you decide to unwind and relax, do so in front of a display with images that realistic and natural—with HDR. Acer’s HDR Ready1 displays utilize an edge array with global dimming which increase the overall contrast, making black areas darker and white areas bright.

No Screen Tearing

Say goodbye to stuttering and tearing with AMD® Radeon FreeSync™2. Video playback is quicker, easier and smoother as the monitor’s refresh rate is synched to your computer’s framerate.

Eye Safety First

Impeccable Placement

No matter where you’ve decided to place your display, finding that perfect position is easy with the adjustable stand. Go on and tilt, swivel, pivot, and adjust the height to hit that ergonomic sweet spot.

High-speed Response

Enjoy clear, blur-free images even when the action speeds up with the 1ms3 Visual Response Boost™. A rapid response time ensures images appear clearly as they quickly move across the display, providing more immersive viewing.
