As of the HDMI 1.4 specification, the following cable types are defined for HDMI in general:
- Standard HDMI Cable – up to 1080i and 720p
- Standard HDMI Cable with Ethernet
- Standard Automotive HDMI Cable
- High Speed HDMI Cable – 1080p, 4K 30 Hz, 3D and deep color
- High Speed HDMI Cable with Ethernet
A third category of cable was introduced in October 2015 to certify that cables work at the 18 Gbit/s maximum bandwidth of the HDMI 2.0 specification. This category tests cables at 600 MHz (2160p60 resolution), certifying them as Premium High Speed. 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. These cables are marked with an anti-counterfeiting authentication label and are defined as:
- Premium High Speed HDMI Cable – 4K 60 Hz, Rec. 2020, and HDR
- Premium High Speed HDMI Cable with Ethernet
In conjunction with the HDMI 2.1 specification, a fourth category of cable was announced on January 4, 2017, called "48G". The cable is designed to support the 48 Gbit/s bandwidth of HDMI 2.1, supporting
4K,
5K,
8K and
10K at 120 Hz. The cable is backwards compatible with the earlier HDMI devices, using existing HDMI type A, C and D connectors, and includes HDMI Ethernet.
