A:AnswerIf you do use an external Roku device, be careful which one you buy. They don't all have the same specs. I use a Roku Ultra and it seems to work well with this TV. Also be sure to use HDMI 2.1 cables with the Roku.

A:AnswerI use it with an Apple TV 4K and of course you can use all AirPlay features with the Apple TV. One bad thing is that the TV doesn't turn off when you put the Apple TV to sleep. Pretty much every other manufacturer allows the Apple TV (and other external devices) to power off their TVs. I don't use the built in apps due to serious privacy concerns so I don't know if there is any native Apple support.
A:AnswerBoth the R635 model and this R646 model feature full array Mini-LED backlight display technology with Contrast Control Zone Technology. Hope this helps! Thank you, TCL Customer Support
A:AnswerNot exactly. The hardware has been upgraded, there's HDMI 2.1 ports, and it includes a google assistant voice recognition bar (which you can disable) to help control the TV with your voice or other devices.
This set is an upgraded version of the R635 but doesn't have very significant upgrades aside from HDMI 2.1 which is a big deal for gamers.
