HDMI was designed to fix the problems with DVI and HDCP along with adding audio. This make the cable and connector more desireable for television and multimedia computers.

Over time HDMI with the backing of the entire industry helped make sure it was the done right. HDMI works which is what consumers want.

HDMI 1.0

The revision was published December 9, 2002. It took several years before this became widespread.

HDMI 1.1

The revision was published May 20, 2004. It added DVD audio to the standard.

HDMI 1.2

The revision was published August 8, 2005. It  added the option of One Bit Audio, used on Super Audio CDs, at up to 8 channels

HDMI 1.3

The revision was published June 22, 2006. It increased the single-link bandwidth to 340 MHz (10.2 Gbit/s).

With a dongle and a cable from the S/PDIF older cards like our GTX 260 can support HDMI 1.3 which works with our Asus PA238QR panel.

HDMI 1.3 also has a new mini cable, like the one seen on our GT 640 card. The smaller connector makes it easier to increase the number of ports on a video or a panel. It also makes it easier to use with thin portable machines.

HDMI 1.4

The revision was published May 28, 2009. Our GTX 660 Ti has support for HDMI 1.4 which we use with our Asus PA238QR panel.

HDMI 2.0

The latest revision is 2.0 (September 4, 2013) which bumps the bandwidth enough to support 3820×2160 displays with 60 frame per second video. It may take a few years for HDMI 2.0 to become common, there is a lot of inertia with televisions which are slow to be replaced.

Video cards have recently had HDMI 2.0 added to the options, check specifications to be certain. Adapters for DisplayPort are an option for older cards but beware of some models that are HDMI 1.4 and are using reduced chroma subsampling

The GTX 960, 970, 980, 980Ti, Titan-X are the only NVIDIA cards with known HDMI 2.0 support. AMD as of Q1 2016 still does not have a HDMI 2.0 card.

HDMI 2.1

HDMI 2.1 was released on November 28, 2017 but implementation was very slow.
