Our take on the Acer EK321QK 31.5" UHD 4K HDR Monitor

The Acer EK321QK is a 31.5-inch 4K monitor built on a VA panel, aimed at desk work and media viewing rather than fast gaming. It gives you a large 3840 x 2160 canvas, three input types (HDMI, DisplayPort, VGA) and built-in speakers, which is more connectivity than many budget 4K screens offer. The VA panel brings deep blacks and good contrast but slower pixel response and narrower viewing angles than IPS rivals. At 60 Hz with a 4 ms response time, it suits office work, streaming and photo viewing more than competitive shooters.

Questions and answers

Is this monitor good for gaming?
It is a 60 Hz panel with a 4 ms response time, so it is fine for casual games but not for competitive shooters. Gamers wanting high frame rates should look at 144 Hz monitors.
Does it have built-in speakers?
Yes. The monitor includes built-in speakers, so you do not need separate desktop speakers for basic audio.
What devices can I connect?
It has HDMI, DisplayPort and VGA inputs. That covers modern PCs and consoles as well as older machines with VGA output.
Is a VA panel good for office work?
Yes. VA gives strong contrast and deep blacks, which helps with text and documents. Its narrower viewing angles matter less when you sit directly in front.
Does it support HDR?
It is marketed as HDR, but with 300 cd/m² brightness the HDR effect is limited. Treat it as a standard 4K display rather than a true HDR screen.
Can I mount it on a wall or arm?
The monitor is light at around 8 lb, which makes it manageable on a VESA arm or wall mount. Check that your mount matches the monitor's VESA pattern before buying.
