Which mini PCs it fits

A monitor needs a matching video output, and this one accepts HDMI, DisplayPort 2.1 or Thunderbolt 5. The GMKtec NucBox K13 connects through HDMI 2.1 and the HP Z2 Mini G1a through DisplayPort 2.1. The GMKtec NucBox G3 fits with a caveat: 120 Hz at this resolution is not confirmed for its output. Fit is not confirmed for the Beelink GTi14 Ultra.

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

Common questions

Will this monitor power my mini PC over USB-C?

LG does not state USB-C power delivery for this monitor, so we cannot say it will charge anything. USB-C power also does not run a mini PC, which uses its own power supply.

Is this the same monitor as the 40U990A-W.AEU?

Yes, apart from the part number: 40U990A-W.AUS here and 40U990A-W.AEU on the other. Every other specification is the same.
