Description
The Xiaomi TV Stick 4K (2nd Gen) plugs into the HDMI port of a TV or monitor and turns it into a MassCasts digital signage screen. It runs Google TV, outputs 4K with Dolby Vision and HDR10+, and connects over dual-band Wi-Fi.
For light use only. The stick is a low-cost way to put MassCasts on a TV you already have, such as a menu, notice or welcome screen used for part of the day. For screens that run all day, every day, choose a commercial signage display with Android built in.
MassCasts is the digital signage software from Mass Coms, £99 per screen per year with one licence free when you book 3 or more screens. It is billed by Mass Coms; the stick is supplied by TopAV.

Frequently asked questions
Does the Xiaomi TV Stick 4K run MassCasts?
Yes. It is the low-cost MassCasts player stick TopAV supplies for existing TVs. Install the MassCasts player app, open it once and pair the screen in your MassCasts dashboard with the 6-digit code it shows.
Can I use it for a screen that is on all day?
It is for light use only. For screens that run all day, every day, choose a commercial signage display with Android built in, such as the iiyama ProLite Android 14 range, which runs MassCasts with no separate player.
Does it need a network cable?
No. It has no network port and connects over 2.4 GHz or 5 GHz Wi-Fi.
What is in the box?
The stick, a remote control, a power adapter, a USB power cable, an HDMI extension cable and a user manual.
