This is my challenge: I have a 60" 4K UHD TV, Home Theatre System, 4k Blu-ray player, and cable box. The guy who installed them ran all cables through the wall. I need to switch one of the HDMI cables because it is not 4K compatible. Unfortunately, it goes from the surround system (output) through a hole in the wall, to another hole to the TV (input). I tried to tape them together. But as I pull the cable, it does not move easily, as if it were fastened down.

you can try to tape the new HDMI cable to the old one and fish it through the wall. Hopefully you wire isn't stapled to anything.
