Yeah, Samsung doesn't pay the fees to Dolby for their Dolby Vision HDR. It does support HDR10 and HLG. I don't think I've found anything that is DV only when it comes to HDR. It might be out there, I just haven't found it.love the sammy. just a heads up, it doesnt support dolby vision from reading the specs. i didnt read through it as much.
plus, after my LG was having trouble with HDR Dolby vision, i turned it off. was it due to my player? sony 700? or my almost 5 year old LG tv? sure. i was dead tired already and knew my wife wont let me buy a new tv anyways since im still not working.
TCL is the brand i was looking for! i saw a thread earlier that referred to its technology, including the Hisense model too...If you are looking at Vizio, you should also look at TCL's higher end sets. IMHO, they are eating Vizio's lunch on both price and picture quality.
