In ELI5;

When you’re playing a game for example, your Computer builds the **entire world,** (This would be rendering the world )

Lets say, you’re in this world you just built and you take your phone/camera out and record a video in this world, now, you’re only see a part of this world through the video you taken right? like you can’t go into the world through a video recording.

Now, your phone isn’t building the world there, your computer is, the video you’ve taken, is only a representation of the world and not the world itself, this is alot smaller, as it is just a representation and much easier to process.

Your TV kinda works the same, it only really shows a representation of these worlds, not the full thing, even in 8k, it’s kinda just like a really good camera, it’s still a lot smaller than what would be necessary to actually make the whole world.

If you watch a YouTube video at 4k/8k, it doesn’t actually take a lot of power, this is kinda why, it’s just smaller.
