The StarTech.com ST121HDBT20L is an HDMI-over-CAT5e/CAT6 extender for sending video to a remote display, supporting 4K at 60 Hz up to 70 m (230 ft.) or 1080p at 60 Hz up to 100 m (330 ft.). It suits home, office, and professional AV setups that need long-distance display connections over one cable.
Recommended For
- AV installers fitting a conference room, classroom, or similar space can place an HDMI source away from a remote display and carry the signal over an existing Cat5e/Cat6 cable run.
- Digital-signage operators who need to locate a display far from its HDMI source can use one Cat5e/Cat6 cable for the connection, with 4K at 60Hz supported up to 70m and 1080p at 60Hz up to 100m.
- Installers working where the remote display has limited access to power can benefit from Power over Cable, which lets the transmitter and receiver share a single power adapter connected at either end.
- Users who need to control a source device from the display location, such as a presenter using equipment installed elsewhere in the room, can use the included IR receiver and blaster for remote-control extension.
