The StarTech.com ST121HD20V is an HDMI-over-Cat6 extender kit that carries 4K at 60 Hz, HDR, and 4:4:4 chroma over up to 165 ft. of Cat6 cable, making it suitable for home theaters, conference rooms, and other setups where a display is far from the HDMI source.
Recommended For
- Classrooms and boardrooms that need to send HDMI video from a source to a distant projector or display over an existing CAT6 run, rather than routing a long HDMI cable through walls or ceilings.
- Digital-signage installers extending a fixed HDMI source to a remote screen over a direct CAT6 cable, with support for 4K 60 Hz and HDR within the stated 165 ft (50 m) limit.
- Installations that want a local display near the HDMI source as well as a remote display; StarTech lists a local HDMI output on the transmitter.
- Blu-ray or streaming-device setups that need HDCP 2.2 compatibility while carrying HDMI video to a more distant display over CAT6.
