The fourth version, superMHL, increased bandwidth by operating over multiple TMDS differential pairs (up to a total of six) allowing a maximum of 36 Gbit/s. [224] The six lanes are supported over a reversible 32-pin superMHL connector, while four lanes are supported over USB-C Alternate Mode (only a single lane is supported over micro-USB/HDMI). Display Stream Compression (DSC) is used to allow up to 8K Ultra HD (7680 × 4320) 120Hz HDR video, and to support Ultra HD 60Hz video over a single lane. [224] See also [ edit ] Whereas active HDMI cables require a separate power supply fed from an external source, HDMI Cable Power cables can draw up to 300 mA from the 5V supply of a source directly from the HDMI connector, allowing for less convoluted cable runs in home cinema systems. Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity.

The longest HDMI cable we have ever seen a compliance test certificate for is our own Series-1, which passed ATC testing at 45 feet under HDMI 1.3a (CTS 1.3b1). If you have a 4K Ultra HD TV and 4K source components, the switcher must also be 4K compatible. If you need to pass HDR-encoded or 3D video signals, your HDMI switcher must have those capabilities.

What is HDMI 2.0?

In September 2009, AMD announced the ATI Radeon HD 5000 series video cards, which have HDMI 1.3 output (deep color, xvYCC wide gamut capability and high bit rate audio), 8-channel LPCM over HDMI, and an integrated HD audio controller with a Protected Audio Path that allows bitstream output over HDMI for AAC, Dolby AC-3, Dolby TrueHD and DTS-HD Master Audio formats. [175] [176] [177] The ATI Radeon HD 5870 released in September 2009 is the first video card that allows bitstream output over HDMI for Dolby TrueHD and DTS-HD Master Audio. [177] The AMD Radeon HD 6000 Series implements HDMI 1.4a. The AMD Radeon HD 7000 Series implements HDMI 1.4b.

[95] :§6.5 As reported by Ars Technica in late 2021, many HDMI 2.1 capable devices might not actually have these high-end features after all. Apparently that's thanks to a quirk in the official HDMI guidelines – it turns out that the spec for HDMI 2.0 has been wholly replaced by HDMI 2.1, instead of simply building upon it. a b "HDMI Specification Marks 10-Year Milestone as De-Facto Standard for HD Connectivity".
