Samsung KS8000... Most highly rated TV series of 2016 for HDR gaming. When researching keep your eye on the lag times of the TV. Some will post great numbers in HD or even UHD but the lag drastically increases when you introduce HDR in the mix. The KS8000 has the lowest input lag with HDR, and has a superb colour reproduction. I researched for a solid couple of months, wanted an OLED but feel like the tech is to infant right now.
HDR is nice, but it's not like it was going from 480i to 1080p... It's subtle at times but definitely there. The KS8000 will auto detect an HDR signal and enable the settings (backlight gets cranked to max) automatically. However, you have to manually change the backlight when in game mode and an HDR signal is running.
Also, I paid just under list price around November of last year. About $2300. Found a sketchy website that had it listed for $850 less online and the dumb-ass at Best Buy price matched it so I ended the day getting it for a really solid price.
