My Moto Edge 2024 has "Ready For" which is basically this still today. I plug in the USB-C cable normally connected to my work MacBook and I instantly get a full desktop experience; mouse, keyboard and sound included.

It's how I play Minecraft with my kids when they get the itch. Sometimes if I know I'm only gonna be zoning out on Youtube at night I'll use to to save a few watts too.

It can do 1440p at 120hz, all on a really affordable phone. It's nice.
