New USB Type-C to HDMI spec lets you ditch the dongle". Ars Technica. September 5, 2016 . Retrieved May 5, 2017. In addition to the features in common with HDMI (such as HDCP encrypted uncompressed high-definition video and eight-channel surround sound), MHL also adds the provision of power charging for the mobile device while in use, and also enables the TV remote to control it. Although support for these additional features requires connection to an MHL-enabled HDMI port, power charging can also be provided when using active MHL to HDMI adapters (connected to standard HDMI ports), provided there is a separate power connection to the adapter.

Although no maximum length for an HDMI cable is specified, signal attenuation (dependent on the cable's construction quality and conducting materials) limits usable lengths in practice [70] [71] and certification is difficult to achieve for lengths beyond 13m. [72] HDMI 1.3 defines two cable categories: Category 1-certified cables, which have been tested at 74.25MHz (which would include resolutions such as 720p60 and 1080i60), and Category 2-certified cables, which have been tested at 340MHz (which would include resolutions such as 1080p60 and 4K30). [5] :§4.2.6 [63] [73] Category 1 HDMI cables are marketed as "Standard" and Category 2 HDMI cables as "High Speed". [3] This labeling guideline for HDMI cables went into effect on October 17, 2008. [74] [75] Category 1 and 2 cables can either meet the required parameter specifications for inter-pair skew, far-end crosstalk, attenuation and differential impedance, or they can meet the required non-equalized/equalized eye diagram requirements. [5] :§4.2.6 A cable of about 5 meters (16 feet) can be manufactured to Category 1 specifications easily and inexpensively by using 28 AWG (0.081mm 2) conductors. [70] With better quality construction and materials, including 24AWG (0.205mm 2) conductors, an HDMI cable can reach lengths of up to 15 meters (49 feet). [70] Many HDMI cables under 5meters of length that were made before the HDMI 1.3 specification can work as Category 2 cables, but only Category 2-tested cables are guaranteed to work for Category 2 purposes. [76] The Blu-ray Disc Association (BDA) spokespersons have stated (Sept. 2014 at IFA show in Berlin, Germany) that the Blu-ray, Ultra HD players, and 4K discs are expected to be available starting in the second half to 2015. It is anticipated that such Blu-ray UHD players will be required to include a HDMI 2.0 output that supports HDCP 2.2. The features defined in the HDMI Specification that an HDMI device may implement are listed below. For historical interest, the version of the HDMI Specification in which the feature was first added is also listed. All features of the HDMI Specification are optional; HDMI devices may implement any combination of these features. a b Simon Baker (December 23, 2021).

The 48 Gbit/s bandwidth provided by HDMI 2.1 is enough for 8K resolution at approximately 50 Hz, with 8 bpc RGB or Y′C BC R 4:4:4 color. To achieve even higher formats, HDMI 2.1 can use Display Stream Compression with a compression ratio of up to 3∶1. Using DSC, formats up to 8K ( 7680 × 4320) 120 Hz or 10K ( 10240 × 4320) 100 Hz at 8 bpc RGB/4:4:4 are possible. Using Y′C BC R with 4:2:2 or 4:2:0 chroma subsampling in combination with DSC can allow for even higher formats.

[79] In addition to expanding the set of cable testing requirements, the certification program introduces an EMI test to ensure cables minimize interference with wireless signals.
