I had to take a long cable 7-10m (to PC) for TV, I have the same wire with 3m and everything is perfect (4k 60 4.4.4), I took 7.5m = no signal, something like 50 attempts and changing the power to the filter from I managed to start the PC but with 4k 30 4.2.0, another 2k30 and the current at fhd 60. Check the packaging, the sites change the length numbers but not the packaging. up to 3m cable chic for the price / quality
