Am getting X1 HD service on one TV will a second TV with a smaller box also receive HD signal
I have Xfinity HD service with an X1 box on one TV and a smaller HD-DTA/100u box on bedroom TV.
The smaller box is connected to the bedroom hdtv tv via HDMI cable but the display is showing a letterboxed image. I have tried adjusting the small image through the comcast box settings but the aspect ratio setting is greyed out.
Any idea what the problem might be
Thanks for your help
