Does anyone know if there is a device that let’s you combine two video inputs and then outputs one split screen view.

I’ve read some tvs have that feature but I don’t have the option on mine so maybe there is a separate device that can do it.

The goal is to be able to play split screen the games me and the wife used to play but from the couch now that we have a baby gaming at our desk isn’t really a thing anymore so I’m thinking split screen with xbox controllers would be nice
