CES 2019 marked the first time most of the world's biggest TV makers introduced 8K TVs. And it's good news that most will include the next-gen connection that will actually allow 8K TV shows, movies and games to get to those TVs.

For most people with current and even near-future 4K TVs, HDMI 2.1 isn't a big deal, and HDMI 2.0 is plenty. It will handle 4K resolution at frame rates up to 60 per second, and even some varieties of 8K (24 and 30 fps). It also doesn't require new HDMI cables.
A 4K TV like LG's rollable OLED can use HDMI 2.1 features like ALLM and VRR.
