100' HDMI Setup With Error Message
Hey guys. I have absolutely 0 knowledge about anything HDMI. Ive researched here on this site and in the forums and have just become increasingly confused. Back in August 2016 I had my 60" LG tv mounted as well as the components (DirectTV) hidden. The run of HDMI ended up being 100' when all said and done (pulling through walls etc) This worked well up until a couple months ago when I received an error message on my TV: "your tv does not support this programs content protection. Replacing the tvs hdmi cable with component cables will allow you to view the program".
I went to Best Buy and the rep at Magnolia (?) explained that what I was trying to do was going to be very expensive, he got into Baluns, Cat cables etc..... he explained how the 100' run was too long, which I understand and that it was a handshake issue and HDMI 2.0 issue etc... So I bought a wireless transmitter as a temp solution and the picture quality is taking a hit. Directv says the TV is obsolete (Its a 2013) and Best Buy says the TV is fine.
So my question is, what caused this error message and how do I remedy this? Clearly a 100' HDMI run is too long. At this point Id like to get a setup for future 4k and a bigger TV if Im going to do it right. Would a Balun or HDMI extender be better? Which Cat cable? I greatly appreciate the help!!!!!
