For those who may be unaware there is a new HDMI 2.1 standard (http://www.hdmi.org/manufacturer/hdmi_2_1/) with some good features which should start shipping on 2018 TVs. However the new 4K Apple TV is limited to 2.0. Which may not be a big deal as most features are forward-looking, but may be worth keeping in mind for those considering buying a new TV or an Apple TV. (The Xbox One X releasing November 7th is expected to be the first device with 2.1, so it's possible Apple could have included it, or waited a couple months.) According to news reports (https://www.cnet.com/news/hdmi-2-1-what-you-need-to-know/) it's possible some features can be enabled on 2.0 through a firmware update, although there is no guarantee. Apple users may have to wait until the next Apple TV for this and an improved remote, presumably at minimum two years from now, unless Apple gets serious and releases that 60" television set next year. One feature I'm curious about is VRR (variable refresh rate) which is used for gaming, but am wondering if it can be used to solve the 24p problem, as opposed to relying on TV makers to reverse telecine properly.
