What is an HDMI extender, and why do I need one?
An HDMI extender is also known as an HDMI equalizer or HDMI booster and can boost an HDMI signal. Sometimes when running a long HDMI cable, the device powering the signal is not strong enough to supply the monitor with a proper signal. This could result in signal degradation and/or loss of picture. We recommend using cables with a built-in HDMI equalizer if you are running an HDMI cable longer than 50 feet or for Category 2 applications longer than 30 feet.
