Here's Linus Tech Tips with a chiropractor's dream: playing a single PC game across 16 monitors at the same time.
First they try Minecraft:
Then Tomb Raider, which didn't really work. So it was off to Half-Life 2:
Then PUBG, which didn't work either, but Civ V sure did. Please note the hilarious placement of the menus in these games (Civ's mini-map in the bottom right is fantastic).
This isn't something you would do to enjoy these games. Between the bezels and the framerates they're practically unplayable. But as a thing to do just so you can say you've done it, this is wonderful.
