21.4 inch QLED portable monitor

This 21.4 inch Full HD portable monitor uses a VA QLED panel with 125 percent sRGB coverage and 350 nits brightness. It targets laptop, mini PC and console users who need a larger second screen for spreadsheets, video calls or gaming on the move.

Single cable setup with VESA option

The display connects over a single USB-C or HDMI link so driver installs are rarely needed. The integrated stand adjusts through multiple angles and a 100 by 100 millimetre VESA pattern accepts monitor arms, though the stand itself cannot be removed for flush mounting.

Steady 100 Hz output with 1ms response

A 100 Hz refresh rate and 1 millisecond response time keep motion sharp during long gaming or editing sessions. The 1200 to 1 contrast ratio and 178 degree viewing angles maintain colour consistency, while 350 nits brightness resists washout under sustained indoor lighting.

Questions about this item

How do I confirm the 100Hz refresh rate is active after connecting the monitor?

Open your device's display settings and set the refresh rate to 100Hz; the on-screen menu will then show the current timing as 100Hz.

What cables are included and which ones must I buy separately for my laptop?

The box contains the monitor, an adjustable stand, and a VESA 100x100mm mounting kit; you must supply a compatible USB-C or HDMI cable for video and power.

Which screen size should I choose — 21.4 or 21.5 inches?

The product is a single 21.4-inch model; the 21.5-inch figure is a nominal panel diagonal, so there is no separate version to select.
