I downloaded the latest version of TV to test the ability to use across multiple screens. After following numerous examples on YouTube on how to use the software, nowhere is the demonstration of how to activate the feature within TV.
Is there something that must be done with the operating system before trying to duel screen via TV? I noticed several other users asked this question several times over a period of a year or so with only one reply with a link but that link led to nowhere suggesting perhaps it may have not been relevant to the problem.
