Forget trying to run extra long HDMI cables through floors and walls. They’re expensive and the longer they are, the less likely they’ll provide a clean signal. New HDMI extenders can send HDMI over single CAT5E or CAT6 cable to 40, 50 or 100 meters!

If you need a super long run in an office, restaurant, bar or for commercial signage, or need to distribute the same HDMI source to multiple destinations, the following product allows point-to-point HDMI over a single CAT6 up to 100M plus it is HDBaseT enabled. The sender and one or more receivers can connect to a 10/100 or Gigabit Ethernet switch for point to multi-point HDMI distribution of the same source at a very economical price.
