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, IEEE registration number 00 0C 03 means this is a "HDMI Licensing, LLC" specific data block (contains HDMI 1.4 info), C4 5D D8 means this is a "HDMI Forum" specific data block (contains HDMI 2.0 info), 00 D0 46 means this is "DOLBY LABORATORIES, INC."
High-Definition Multimedia Interface (HDMI) 2003: 19 pin HDMI Type A/C: 10240 x 4320 @ 120 (version 2.1) [11] Many A/V systems and video cards (including motherboards with IGP) High-bandwidth Digital Content Protection (HDCP) encryption is mandatory.

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.
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 gained similar capability in version 2.0, which increased the maximum allowed transmission speed to 600 MHz TMDS (18 Gbit/s). The NVIDIA GeForce GTX 980, launched in late 2014, was the first graphics card to implement this capability, which was sufficient for 5120 × 2880 at 30 Hz with 30 bit/px color depth.
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.
