I have a monitor and a TV, at first I connected the monitor only and it worked, but when connecting both at the same time the monitor lost signal and even though both screens were recognizing the input, it didn't send signal to neither. Afterwards it just didn't ever send signal, not even with only one connected. I'd assume it has to do with power supply for the adapter, but I have no idea. Maybe it's just bad. I bought it from aliexpress. First time something from there doesn't work for me. Am I just retarded from trying to do it this way? Any alternatives for what I'm trying to do?
