How big is your TV?

O and it may be nice to point out I'm a gamer. I don't have cable lol. I use Netflix mostly and buy movies. Most but not all I watch are streamed thru my Xbox one or Xbox one S.
4k TV's just have what appear to be more depth in their picture almost 3d without being 3d. Walking in on a **** you may think someone was watching someone thru a window lol well almost. My mom had to ask me if the show we were watching g was CG or real footage. She was shocked when I told her the jellyfish were real and I was able to point to out the floaty objects and gunk in the watef
