Tv's with DTAs - Time Warner TV

This question is about "Tv's with DTAs", with Time Warner Cable TV and apps. We have two tv's with DTAs. Our main tv has an HD box.

How do we see the on screen channel line-up with the DTA tvs? The guide used to be channel 84. Does not do it anymore.

This topic covered Tv's with DTAs, and TWC cable tv service.
