I've got one setup at work as a display for some networked security cameras. Displays 4 concurrent 720p streams on a TV for the office 24/7. Cheaper than Ubiquiti's solution [0] as we didn't need more than the 4 streams.

At home I've got one for Home Assistant, one as a TV box because Netflix's sharing blocking check is only on smart TV apps. I've also got multiple as 3D printer controllers (klipper/octoprint).
