The Tripp Lite 50 ft. Standard-Speed HDMI Cable allows interconnection between digital display devices such as digital TVs, plasma displays and LCD TVs and projectors to digital source devices such as set-top boxes, Blu-ray players and A/V receivers. It supports iPad 2 video mirroring when used with an optional Apple Digital A/V Adapter, sold separately. HDMI ensures the best A/V signal is always sent from the source to the display. It allows uncompressed video with multichannel audio data to be input to the display device through 1 cable. In most applications where the HDMI cable exceeds 16 ft. a separate signal booster (like the Tripp Lite B122-000-60, sold separately) will need to be used with this cable to ensure a signal strong enough for your display.
