Tired of screen tearing and lag ruining your gaming nights? The Acer ED320QRS3 curved monitor delivers ultra-smooth motion and immersive visuals, so you can stay ahead of the competition.
This 31.5-inch VA panel combines a 1500R curvature with a blazing 180 Hz refresh rate, giving you fluid gameplay and a truly panoramic view. With a 1 ms GTG response time and AMD FreeSync Premium, tearing and stuttering disappear, while HDR10 boosts contrast for brighter highlights and deeper shadows. The display reproduces 16.7 million colors within a 72% NTSC gamut, and its 178° horizontal and vertical viewing angles keep the picture consistent from any seat.
The monitor features a sleek frameless black design that fits any gaming setup. Built-in dual 2 W speakers provide decent audio without cluttering your desk, and the HDMI 2.0 (two ports) and DisplayPort 1.4 connections ensure compatibility with PCs, consoles, and laptops. Low Blue Light and flicker-free technologies protect your eyes during long sessions. Although the stand offers a tilt range of -5° to 20°, you can also mount the unit on a wall or VESA-compatible arm using the 100 × 100 mm bracket and Kensington lock slot for added security.
Enjoy a competitive edge with ultra-fast 180 Hz refresh and 1 ms response, eliminating motion blur in fast-paced shooters and racing games. The HDR10 support and high dynamic contrast bring richer colors and deeper blacks, making both games and movies look more lifelike. Eye-care features like Low Blue Light and flicker-free reduce fatigue, so you can play longer without strain.
Connect the monitor to your gaming rig via HDMI or DisplayPort and enable FreeSync in your graphics driver for seamless performance. The high refresh rate shines in competitive titles like first-person shooters, where every frame counts, while the curved screen enhances immersion in open-world adventures and cinematic experiences. For productivity, the Full HD resolution and wide viewing angles make multitasking comfortable, and the built-in speakers handle conference calls without extra hardware.
