Acer CE320QK X — 31.5" 4K QD-OLED monitor at 240Hz, in white
31.5" QD-OLED3840 × 2160240HzDisplayHDR 400 True Black
The Acer CE320QK X (UM.JC0EE.X01) is a 31.5-inch Quantum Dot OLED monitor with 4K UHD resolution, a 240Hz refresh rate and 0.03 ms response, finished in white, for gamers, video editors and anyone who wants a large 4K screen with OLED contrast.
At 31.5 inches, 4K can be used at 100–125% scaling, so you get a genuine increase in workspace as well as sharpness. Every pixel produces its own light for true blacks, the panel covers 99% of DCI-P3 and is certified VESA DisplayHDR 400 True Black, and two HDMI 2.1 ports, two DisplayPort 1.4 inputs and USB-C cover a PC, a console and a laptop.
Before you order: The panel is glossy: it shows deep blacks but reflects windows and lamps, so position it away from direct light. Acer does not publish a USB-C charging wattage — do not count on it to power a laptop under load.
What's in the Box
- Acer CE270K X monitor with stand
- Power cord (EU)
- HDMI cable
- USB-C cable
- USB 3.0 cable
What It Means in Practice
- 4K at 31.5" is about 140 ppi — sharp text with enough room for several windows side by side.
- 240Hz with 0.03 ms response makes fast games look clear, with AMD FreeSync Premium Pro for tear-free play.
- The built-in USB hub lets keyboard and mouse follow the connected computer.
- As with all OLEDs, avoid leaving static bright elements on screen for many hours — use a screensaver or turn the display off when idle.
What Will Not Work
- A matte, reflection-free picture — the screen is glossy.
- Guaranteed laptop charging over USB-C — Acer does not publish a power-delivery rating.
- Portrait mode — the stand adjusts height, tilt and swivel but no pivot is listed.
- 4K at 240Hz from every source — your graphics card must support it over HDMI 2.1 or DisplayPort.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
The CE320QK X is the larger sibling of the CE270K X: same 4K, 240Hz QD-OLED specification, but at 31.5" it works as a real productivity screen as well as a gaming one. Keep the glossy panel away from windows, and if desk space matters, mount it on one of our monitor arms and stands rated for 32" screens.
✓ Buy it if you want a large 4K OLED screen with high refresh for both work and gaming.
✕ Skip it if your room is bright with light behind you, or you need a guaranteed USB-C laptop charger.
→ Also consider the 26.5" CE270K X if your desk is shallow or you prefer higher pixel density.
