What's the maximum length of HDMI cable that I can use with KLIK?

HDMI cable length depends on the cable itself, as well as the device (display) at the receiving end of the signal.

Signal loss occurs on HDMI cables based on the inherent "impedance" of the cable itself. Impedance is an electrical parameter that varies, depending on the size of the electrical conductor used in the cable. Smaller conductors have higher impedance, and consequently only work well at short distances. Larger conductors, used in larger cables, exhibit lower impedance, and can work well at longer distances.

The other factor, is the display that the HDMI cable connects to, in order to reproduce the signal. Most current displays have a feature that blanks the screen when an input signal is below a certain threshold, to prevent the display of static or a distorted signal. If the HDMI signal that reaches the display is below that threshold, the screen will go blank, appearing like there is no signal present.

We ship the KLIK Boks with a slim, 1 meter HDMI cable, suited for direct connection to a display. Longer cables can be used, but as per the above, performance is not guaranteed. Given the variables, we recommend that you test your proposed configuration before installation. In the event that the configuration does not yield the desired result, there are several options for extending an HDMI signal, including signal boosters and alternative cabling.
