![]() ![]() We're already seeing TVs that are capable of higher frame rates, plus higher resolution TVs, like those with 8K. Though most current HDMI cables can handle nearly all of today's content, the TV industry never sits still. This is the same as HDMI 2.0a/b, and is what makes wide color gamut possible. On the color front, 2.1 supports BT.2020 and 16 bits per color. You should be able to get 4K/60, and a basic 8K/30, with current cables, but the rest will need an Ultra High Speed HDMI cable. The increased resolution and frame rate possibilities are a futurist's dream: The main sources that can take advantage of 2.1 right now are the PlayStation 5 and Xbox Series X, as well as high-end graphics cards.Many new TVs have at least one HDMI 2.1 input.New cables are required for higher resolutions and/or frame rates.Can carry resolutions up to 10K, frame rates up to 120 frames per second.Improved bandwidth from 18 gigabits per second (HDMI 2.0) to 48Gbps (HDMI 2.1).The physical connectors and cables look the same as today's HDMI.Sarah Tew/CNET The really short versionÄon't like reading (much)? Here are the highlights: Inputs with HDMI 2.1 features, like the one on this Samsung TV, primarily cater to gamers right now. Many midrange and higher-end sets support the new connectivity standard, though, so it's worthwhile to understand what it means if you are looking to purchase soon. If you're on a budget, those new consoles will play perfectly well (and still look spectacular) on a TV that lacks HDMI 2.1. For most people the extra features are not a good enough reason to buy a higher-end TV. That doesn't mean you need HDMI 2.1, however. You'll want a TV that supports at least some HDMI 2.1 features. HDMI 2.1 is also on both of the next-generation game consoles, the PlayStation 5 and Xbox Series X. The standard is found in the best new TVs, including recent models from LG, Samsung, Sony, TCL, Vizio and more. The latest version, called 2.1b, is only a small update, but 2.1 in general is a big deal with lots of performance improvements and new features. Even though the cable looks the same, modern HDMI connections are vastly more capable than when they first arrived over 20 years ago. ![]()
