Works great at 40’.
Make sure you observe directional connection. It definitely does not work connected backwards.

These cables are awesome they're small they're portable they bend very easily and you can run them 300' and not have an issue I love them for the versatility that they have and they bring an excellent picture to any video source that has H DMI capability
Worked great until the dog chewed it.Will order another sometime.
