Just moved into a house.\n\nI looking at the HDMI cables that were run from my AV cabinet under my stairs to the TV mounts all the HDMI cables are labled HDMI 1.3, so it has ARC.\n\nI want to run a 4K signal from 4K fire stick from my new Denon AVR x2500h to the TV.\n\nIn order for 4K I need a newer HDMI cable??? 2.0? Running one and fishing it will be a huge pain. and the lengh will be about 18 feet or more.\n\nHowever, there also is an unused ethernet cable.\n\nDo the HDMI over ethernet adapters work well? \n\nOr should I tough it out and run a new cable? Is this tool ong of a run??
