Python Digital 4 x 1 HDMI Switcher easily and efficiently integrates multiple HDMI and/or DVI-D compatible equipment. It finally ends the fumbling of cables during frequent plugging and unplugging between signal sources. The HDMI switch enables selection of digital video and multichannel digital audio from different sources, including digital video recorders, cable/satellite digital set-tops, and DVD players, for display on an HDTV or monitor. All that’s required for a quick installation are HDMI male-to-male cables. Or use adapters for DVI-D (video-only) digital connections.
