It's not just the id Software shooter that can be seen in the most unexpected places.
The author of the YouTube channel AllAroundPC presented the results of an experiment with Battlefield 6. He decided to play the shooter on a small round screen of the CPU cooling system.
The screen is intended to be used for monitoring the CPU temperature, but he found a gaming application for the MSI CoreLiquid P13.
This screen has a resolution of 480 x 480 pixels and a diagonal of 2.1 inches, so I had to use a magnifying glass to (as much as possible) see what was happening on the Battlefield 6 battlefields.
