What is HDMI and what are the different versions?
There are some solid options from last year from Sony if you're looking for HDMI 2.1 ports, like the Sony X90J, a native 120Hz TV with two full-spec HDMI 2.1 ports for the Xbox Series X and PS5. If you need an extra cable, or perhaps one that's longer or shorter than the one provided, you'll want to make sure it's fully HDMI 2.1 compliant. Being confident of that just got a fair bit easier, as the HDMI Forum, the organisation responsible for the HDMI spec, recently launched a certification program for HDMI 2.1 cables.

Video formats that require more bandwidth than 18.0 Gbit/s (4K 60 Hz 8 bpc RGB), such as 4K 60 Hz 10 bpc (HDR), 4K 120 Hz, and 8K 60 Hz, may require the new "Ultra High Speed" or "Ultra High Speed with Ethernet" cables. [82] HDMI 2.1's other new features are supported with existing HDMI cables. From a user's perspective, an HDMI display can be driven by a single-link DVI-D source, since HDMI and DVI-D define an overlapping minimum set of allowed resolutions and frame-buffer formats to ensure a basic level of interoperability. In the reverse case, a DVI-D monitor has the same level of basic interoperability unless content protection with High-bandwidth Digital Content Protection (HDCP) interferes—or the HDMI color encoding is in component color space Y′C BC R instead of RGB, which is not possible in DVI. An HDMI source, such as a Blu-ray player, may require an HDCP-compliant display, and refuse to output HDCP-protected content to a non-compliant display. [55] A further complication is that there is a small amount of display equipment, such as some high-end home theater projectors, designed with HDMI inputs but not HDCP-compliant.
