When Battlefield shrinks to 2 inches

A clip on Reddit shows someone playing Battlefield 6 on the tiny display built into an AIO liquid cooler. The rig appears to use MSI’s MPG CoreLiquid P13, which has a 2.1-inch 480×480 IPS panel that Windows treats as a second monitor.
For anyone wondering how this works: the cooler’s screen is a regular USB display, so you can mirror or extend your desktop to it and run anything, including a game. I’m not aware of any reviewer testing AIO screens for gaming, so anything like latency, color reproduction, or refresh rates are not important.

Since many people asked if it was just a looping video, no this is the actual display. MSI Center for this AIO has an option to run the AIO screen as a secondary monitor:
I guess this has no practical use for actual gaming, unless one plans to play Snake or something. Perhaps gamers whose main monitor goes offline, can quickly switch to this as a backup?
