Most current list for the brehs asking
Sorry but
All these companies selling "4K" and "HDR" and only about 15-20 are real from 4 companies
To be listed, the television must support the HDR10 standard at the time of writing (not including "upcoming firmware updates"), must support 10-Bit color (as defined by Rtings, which includes native 10-bit panels without 8-bit banding and 8-bit panels with dithering to create 10-bit colors), and of course have a 4K panel. Input lag isn't really a decider, although if you're a competitive gamer, it should definitely be taken into consideration.
Peak / Sustained brightness has not been used to give or bar entry on to the list, but if there's demand for it, I can create a multiple tier system based on brightness and 10bit vs 8bit coloring. There is of course a difference in HDR quality based on brightness potential of the display.
