HDMI (High-Definition Multimedia Interface) is a format that really seems to work -- Increasing display quality by moving audio/video interconnects for digital TVs from analog to digital, and collapsing 5 or more cables (red, green, blue, audio, left, audio right) into one relatively thin and easy cable.
HDMI cables also are easy to connect, with no tabs or snaps or screws. But that also means they can be too easy to disconnect, and pop off when you're messing with the cabling for all the different devices you want to connect to your display.
One nice answer is the PPC Locking HDMI Cable, which holds on more tightly to the connector to provide a more secure hold and more reliable signal. And there's a push-to-release tab to pop it off easily.
The PPC cables are also shielded and flexible, with gold-plated pins, and are Category 2 to support up to 1080p high-def video.
The PPC Locking HDMI Cables are available in 3 foot length for $48.99, 6 foot for $59.99, and 12 foot for $72.99.

(HDMI also supports digital rights management (DRM) technology -- See my article on Content Protection Technology for Consumer Electronics.)
