Initially thoughts about this TCL 6 series: Popped in the Black Panther 4K disc. Resolution wasn't breath taking. Everything looks clear but nothing I wasn't expecting. The skin tones look amazing though. These women look gorgeous.

I did notice that the blue(green) screen and CG look much more obvious now. I suppose that's due to the higher resolution.
So far I'm very happy with the TV.
I just turned on my OG PS4 and the menu alone already looks significantly better. Everything looks incredibly crisp.
For a $600 55" 4K TV with HDR I think it's a pretty hard deal to beat.

I'm really interested to see Halo 5, Gears of War 4, and Forza Horizon on this thing.
I'll most likely pick up a PS4 at this point within the next few weeks. Especially since this OG looks obviously better already on this TV.
