Hi, while my roof was being redone, I had both a 75 foot hdmi cable and a 75 foot ethernet run laid down. The hdmi was working. However, when they finished installing the roof, both the hdmi and ethernet cables became damaged. A signal tester suggests that only a couple of strands in the network cable are shorted, and presumably there are also good strands left in the hdmi cable. Redoing the cables with the roof now on is not feasible. I have confirmed that I can run hdmi over ethernet if the ethernet cable is in working order. I don't know what the differences are between ethernet and hdmi, but my internet search suggests they are both twisted pairs. I don't know if that means the strands in a hdmi cable can be like the strands in an ethernet cable. It seems like they are both wires, but I don't know if a certain resistance is required. My question is: would it be possible to use working strands from both the ethernet and hdmi cable to create a "good" cable that can serve as an ethernet cable? Or use remaining good strands from the hdmi cable alone to create an ethernet cable? Thanks.
