I am trying to run 3 tv's from 1 computer. The front 2 will b 150 ft. run and the 3rd is only 40 ft. How do I maintain a digital signal for Hidef to the tv's?
If so, first you need a 1x3 HDMI Splitter if you do not want to manually switch cables all the time.
150ft is kinda crazy for HDMI connection unless you want to go with HDBase-T HDMI Extender over CAT
Or, you can try to match a HDMI Extender with a good cable.
