HDMI 2.1 TV: why the new cable standard matters - TechRadar HDMI 2.1 TV: why the new cable standard matters - TechRadar
Unlike HDMI Switchers, which are often powered by the HDMI devices connected to them, most HDMI Splitters need an external power source. HDMI 2.1, however, will ship with eARC, or enhanced Audio Return Channel. With help from eARC, audio bandwidth will be significantly expanded and allow for more audio content to pass through the cable. That should ultimately translate to even better-sounding audio.a b c Michael Stelts (April 17, 2002). "HDMI– Presentation for the HDMI Working Group" (PDF). Copy Protection Technical Working Group.

However, with multiple screens comes the problem of using your media devices – such as streaming devices, gaming consoles, DVD players, etc. – with those multiple tellies. Without buying multiple devices, that is… HDMI 2.1 promises to usher in a new wave of 8K TVs along with much higher bandwidth, better audio and faster gameplay. Here's everything you need to know.

Until recently very few TVs and displays had HDMI 2.1 capability. Granted you still won’t find it everywhere, but now we’re in 2022 it’s becoming much more standard and HDMI 2.1 ports are built into many of the best TVs of 2022.The technology encrypts the signal that comes out of your media device, with your telly decrypting it on the other side.

HDCP’s aim is to protect video feeds from illegal copying, and you need to make sure the HDMI splitter you’re buying supports this standard, otherwise most devices you connect to it won’t be able to broadcast anything to your screens.

It supports 4K at 30Hz, which is good for most uses, except for 4K gaming – so it’s not a good fit for the PS4 Pro or PS5.

Retrieved August 17, 2022. That's still the case with some manufacturers (the Sony A90J OLED features a mix of 2.1 and 2.0 inputs), while others are going all-in on HDMI 2.1 ports on their premium TV ranges. Both LG and Samsung are in this latter camp, and you can expect up to four HDMI 2.1 ports on select sets, especially the new TVs for 2022. The "version" of a connection depends on the versions of the HDMI ports on the source and sink devices, not on the HDMI cable. The different categories of HDMI cable only affect the bandwidth (maximum resolution / refresh rate) of the connection. Other features such as audio, 3D, chroma subsampling, or variable refresh rate depend only on the versions of the ports, and are not affected by what type of HDMI cable is used. The only exception to this is Ethernet-over-HDMI, which requires an "HDMI with Ethernet" cable. a b c d e f g h i j k l m n o p q r s t u v w x y z aa ab ac ad ae af ag ah ai aj ak al am an ao ap aq ar "High-Definition Multimedia Interface Specification 1.3a" (PDF).

We cover why this is important in this guide, but what you need to know is that just because a TV says it has HDMI 2.1 capabilities doesn't mean it'll do everything you need it to. Although HDMI 1.4 does not officially allow 4:2:0 chroma subsampling, NVIDIA and AMD have added 4:2:0 support to their HDMI 1.4 graphics cards via driver updates [140] Total transmission bit rate is equal to the number of data channels multiplied by the bit rate per channel (binary digits transmitted per second). Each channel transmits one bit (binary digit) per signal, and signals at ten times the character rate. Therefore, the total transmission bit rate (in Mbit/s) = 10 × (character rate in MHz) × (# of data channels).
