If you add HD to your X1 service will the slave box also be capable of displaying HD broadcasts?

When I added HD service to my X1 box today the Xfinity person advised my slave box would also be capable of showing HD broadcast channels.  The service was added successfully to my main X1  box

but when I tied the slave box TV it would not display full screen HDTV only a smaller rectangular pictue filling about 75% of the screen.

Thanks for your help

Are you on an HD channel and since you didn’t have HD before are you using HDMI cords?

Andrew I just noticed the channel lineup in the guide with the slave unit does not display any HD tier (800-900) except for 834 and thats displayed in in about a 75% size framed in a black bacground.
