HDMI

What is HDMI?

HDMI - short for High Definition Multimedia Interface - is a video connection standard and cable type for carrying high definition video and surround sound audio to televisions, monitors, and projectors. Since its introduction in 2002, it has become the de facto standard in the entertainment sector. It is ubiquitous on TVs, projectors, game consoles, computers, video players, and streaming sticks.

HDMI ports and connectors

The most common HDMI port is the original HDMI Type A connector, a 19-pin, 13.9mm x 4.45mm connector used on virtually all mainstream consumer electronics equipment. When space is a constraint - like on tiny microcomputers or DSLR cameras - the HDMI Type C (mini HDMI) and HDMI Type D (micro HDMI) connectors might be used instead.

HDMI through the years

When HDMI first debuted in 2002, the consumer electronics industry was beginning the transition to high definition. HDMI 1.0 only offered enough bandwidth for a 1080p display, but successive generations of HDMI significantly upped bandwidth and resolution limits. HDMI 2.0 reigned supreme for many years with 4K video support to match the transition to 4K in the 2010s.

HDMI cables that support older HDMI standards are still available, although you won't be able to take advantage of new HDMI features like 8K video. You'll find these cables advertised as "4K" HDMI cables.

HDMI cable lengths and active cables

HDMI uses copper cabling to transport video, audio, and data between devices. One downside of this approach is that copper cables can only be so long. Traditional HDMI cables top out at about 25 feet. Active optical cables utilize fiber optics to transport data over longer distances, such as from a projector to an entertainment system. Repeaters combine two standard HDMI cables with a signal booster to preserve data across the entire cable run. Learn More

HDMI Ethernet extenders

When even active fiber optic cables aren't long enough, Ethernet can pick up the slack. Specially designed HDMI extenders can convert the signals of an HDMI cable to run over a shielded Ethernet cable. This approach allows for distances of up to 300 feet, but requires a transmitter and a receiver at each monitor.

HDMI vs. USB-C

Both HDMI and USB-C can carry video signals and offer similar performance features, but they differ in form factor and utility. You'll find HDMI ports on large electronics like desktop computers, game consoles, and televisions. USB-C is far more prevalent on mobile electronics like smartphones, laptops, and small form factor PCs.
HDMI vs. USB-C
Despite these differences, it's simple to convert between the two connectors - you'll just need a USB-C to HDMI adapter. There are plenty to choose from, with new models even supporting 8K video.

HDMI vs. DisplayPort

DisplayPort is the second half of the video connector market. The connector is more common on high-end desktop PCs, computer monitors, and laptops than on televisions or game consoles. Like HDMI, DisplayPort supports 8K video and HDR, though it misses out on some advanced features like eARC and ALLM. Learn More
