It seems that this is the cable you want:I'm planning on getting the 75" Q9FN for my new house. The only issue I'm concerned about is that the house has a pre-made AV closet to house the receiver, cable boxes, etc that I plan to utilize. I don't have measurements but I would say it is at least 15-20 feet from where the TV would be. How would this work with the one connect box? I assume they don't make wires long enough to run behind the wall and into the closet?
