How many monitors do you have?

2 monitors, 1 television.
When in the mood, I'll connect my TV to my PC and watch movies in the other room.
More often than not I'll just cast my desktop screen via Chrome Cast.

At work (IT-Support) I have 2 monitors as well.
They are 27" and in 4K, which is actually annoying as fuck, since when you remote desktop to one of our servers, everything gets put to ants size.

My two monitors at home are 24" both, and while one is a cheap iiyama from ages ago, the other one (main monitor) is a BenQ with 144hz.
The day I got my BenQ, and tried the 144hz in-game, I was blown away, and I cannot imagine ever going back down from 144hz.
