Operating like 2 screens?

Hi,

I have 2 21.5's. I'm extremely tempted by a ultrawide.

I'm just curious - Does samsungs easy setting box replicate 2 screens (on split) or just work like windows 11 tiles?

For example can you full screen a video (no borders) on just 1/2 the screen while you do something else on the other screen?

Or play a game full screen on 1/2 while spotify and discord are on the other half without the game being in window mode?

So like... Screen virtualization or something?

I feel like if this can't be done it'll annoy me. I often have full screen yt on monitor 1 and browser in monitor 2, theatre mode and 2 tiles isn't quite the same real estate
