A mini PC runs the same browser as a normal PC, so set it up as in the PC or laptop guide, and add one thing: turn on restart after power loss in its firmware. No particular mini PC has been tested, so we name no model.
What to look for
- HDMI output and a system that runs current Chrome. Windows or Linux both can.
- Restart after power loss. This decides whether the screen returns after a power cut. On NUC models it is the BIOS setting "After Power Failure", described in ASUS's guide. Other makers use other names, so check before you buy.
- A clock battery. Without one, the time can be wrong after a power cut. Ask the seller if the listing doesn't say.
- An Ethernet port, if the room has a cable.
- A mains socket. Many TV USB ports can't power a computer.
Setup
- Follow the PC or laptop guide.
- Turn on restart after power loss in the firmware. The key differs by model. On NUC models it is F2.
- Let it sign in by itself, with a separate account with little access, because anyone in the room could reach it. Microsoft offers Autologon.
- Set active hours so Windows doesn't restart for updates during the day.
Test it once
Unplug the network, pull the mains plug, plug it back in and touch nothing. The screen should return alone, with your times and a small "Offline" label. If it stops at sign-in or an empty desktop, fix that now.
More: running a screen offline, all devices.
