Ive Seen Stranger Things in the upside Down

Hey guys and gals as we all know stranger things season 2 is now available to Stream .

My question is what Android TV box or even hardware is the best to watch at 4k.

Currently I have

Samsung Galaxy s8 (cast) Nvidia shield Tv . No more Google cast 4k I returned it.

LGv30 however it's still inside it's box probably stuck in upside down with Barb.

Samsung 4k 55 inch curve series 6 TV

Netflix with 4k app built in.

Nvidia shield tv. Netflix 4k

Amazon fire TV new addition 4k box with attached cord.

Currently I found setting my TV to HDR mode and Nvidia to be the best but I did have some frame drops.
