HDMI
Everything HDMI, from a short patch cable to a 4K link across a campus. Choose standard and active fiber HDMI cables, then extend the signal over Cat6 or single-mode fiber when the run is too long for copper.
You'll also find 2- and 4-port splitters, switches and matrix switchers, HDMI wall plates, adapters to and from DVI and composite, and testers for checking a cable before you hang the TV.
