After hours of work, I finally got my new 75" TV working ! My iMac duplicates its screen to the TV. I could not get it to work with the HDMI cable I have in the wall (my iMac is on the other side of the wall). I could only get it to work with HDMI-over-Cat6 modules. I believe the signal is too weak for the new TV. (my old 42" TV accepted the signal just fine) I see there are "HDMI repeaters" on Amazon, maybe one of those would help. They are quite expensive, it would be a gamble. I will to more tests later. But at least I can watch my shows. It is not a "smart" TV. It is what I wanted. It turns on and off with the HDMI signal.
