AOC 24E4U

Part number24E4U

The short answer

A 24" IPS monitor at 1920x1080 and 120 Hz with built-in speakers, the AOC 24E4U suits a mini PC owner with a spare HDMI output who wants a compact desk display. HDMI is its only video input, so it relies on your machine's HDMI port rather than USB-C.

Specifications

The 24" IPS panel at 1920x1080 is a compact, desk-sized picture. The 120 Hz refresh rate is the headline spec, though your machine's HDMI output has to carry it. Built-in speakers mean you can get basic sound without a separate pair. With no USB-C video input, a one-cable setup is not possible.

Which mini PCs it fits

This monitor takes video over HDMI only, so the mini PC needs an HDMI output; USB-C video will not work. It fits the Beelink EQR5, GEEKOM A8 Max, GMKtec EVO-X2 and Lenovo ThinkCentre M70q Gen 5, which have an output that matches. It does not fit the Dell Pro Max Micro FCM2250, HP Z2 Mini G1a or Lenovo ThinkStation P3 Ultra SFF Gen 2, because none of their outputs matches the monitor's input. For the ASUS ROG NUC 15 and BOSGAME M5, we have not confirmed it fits, because their HDMI outputs are not confirmed.

Checked against every mini PC sold on amazon.co.uk, from the specifications we hold for each machine.

Before you buy

HDMI is the only video input, so a machine with only DisplayPort or USB-C video outputs will not work. AOC does not state the HDMI version, USB-C power delivery, Thunderbolt input, KVM switch, daisy chain, HDR, HDR certification or VESA mount support. Check the mount before buying if you plan to use a monitor arm.

Common questions

Can I connect the AOC 24E4U over USB-C?

No. It has no USB-C video input; its video input is HDMI, so your mini PC needs an HDMI output to drive it.

Does the AOC 24E4U have speakers?

Yes, it has built-in speakers. AOC does not state whether it has a VESA mount, so check that before planning to use a monitor arm.

Will it run at 120 Hz from my mini PC?

The panel is 120 Hz, but AOC does not state the HDMI version, so we cannot confirm which machines' outputs will carry 120 Hz at 1920x1080.
