Even though the cable looks the same, modern HDMI connections are vastly more capable than when they first arrived over 20 years ago. 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. The standard is found in the best new TVs, including recent models from LG, Samsung, Sony, TCL, Vizio and more. HDMI 2.1 is also on both of the next-generation game consoles, the PlayStation 5 and Xbox Series X. In fact, to get the most out of those consoles you'll want a TV that supports at least some HDMI 2.1 features.
