Choosing the Right Video Cable - HDMI

Choosing the right video cable – HDMI

Did you catch our conversations on VGA and DVI? We’re talking with you all week about different types of video cables and what’s the right choice for your application. Today, we’re going to take a look at HDMI.

HDMI – High-Definition Multimedia Interface


HDMI is a consumer digital video standard. HDMI is in many ways an extension of the DVI format. Does it have a place in the production arena?

In addition to high resolution RGB video HDMI adds support for YCbCr 4:4:4 and 4:2:2, advanced display data, and compressed or uncompressed audio. The newest versions of the HDMI standard even allow for ethernet signal to be transmitted as well. HDMI is HDCP compliant. Standard HDMI cables are capable of carrying resolutions up to 1080i/720p.

High Speed HDMI cables support 1080p up through 4K resolutions. The HDMI standards don’t place any limit on cable length, but like any other standard cable quality affects usable distance. Most commonly available cables are good for about 15’. Better quality cables (category 2) are typically good for about 50’. Active cables, with signal boosters built in, can often carry clean signals for up to 100’. Like VGA, there are several HDMI standards available. 2.0 and 2.0a are the most current.

Many computers, video components, converters, and projects will accept HDMI. Some items to consider is that HDMI is not a lockable connector (it gets pulled out quite easily.) It can be a bit finicky for any or no reason. While it does offer a high quality resolution, you just need to be cautious if using it in a production setting.
