Also known as Category 3 HDMI or "Ultra High Speed" HDMI, the cable is designed to support the 48 Gbit/s bandwidth of HDMI 2.1, supporting 4K, 5K, 8K and 10K at 120 Hz. [82] The cable is backwards compatible with the earlier HDMI devices, using existing HDMI type A, C and D connectors, and includes HDMI Ethernet.
For example, a single link PCIe 3.0 interface has an 8 Gbit/s transfer rate, yet its usable bandwidth is only about 7.88 Gbit/s. z Uses 8b/10b encoding , meaning that 20% of each transfer is used by the interface instead of carrying data from between the hardware components at each end of the interface.

DisplayPort has historically had higher bandwidth than the HDMI standard available at the same time. The only exception is from HDMI 2.1 (2017) having higher transmission bandwidth @48 Gbit/s than DisplayPort 1.3 (2014) @32.4 Gbit/s. DisplayPort 2.0 (2019) retook transmission bandwidth superiority @80.0 Gbit/s.
Four times the resolution of 1080p. Requires a dual-link DVI, category 2 (high-speed) HDMI, DisplayPort or a single Thunderbolt link, and a reduced scan rate (up to 30 Hz); a DisplayPort 1.2 connection can support this resolution at 60 Hz, or 30 Hz in stereoscopic 3D. 3840×2160 (8,294k) 3840 2160 8,294,400 16:9 24 bpp DCI 4K
HDMI 2.0 supports the Rec. 2020 color space. [22] HDMI 2.0 can transmit 12 bits per sample RGB at a resolution of 2160p and a frame rate of 24/25/30 fps or it can transmit 12 bits per sample 4:2:2/4:2:0 YCbCr at a resolution of 2160p and a frame rate of 50/60 fps.
SlimPort is a proprietary alternative to MHL, based on the DisplayPort standard integrated into common Micro-USB ports, and supports up to 1080p60 or 1080p30 with 3D content over HDMI 1.4 (up to 5.4 Gbit/s of bandwidth), in addition to support for DVI, VGA (up to 1920 × 1080 at 60 Hz), and DisplayPort.
