On my one TV, the option on ROKU Home shows “Cable Box” option and brings me back to Xfinity HDMI. On another TV, my ROKU stick does not show any home option for “cable box” so I have to manually go to new input. Have I installed it incorrectly?
Sounds like your one TV may be a RokuTV and your other TV is a non-RokuTV with an attached Roku device via HDMI port or cable.
Roku devices attached to a TV via HDMI do not have or show any Inputs (like cable box, antenna, etc). In this setup, you have to manually select the Input using your TV remote, not the Roku remote.
A RokuTV has the Roku OS integrated into the TV itself, so is showing additional features like color management, TV Inputs, speakers, etc.) It is not seperate from the TV itself. It is a smartTV with an integrated RokuOS.
Roku devices attached to a TV via HDMI do not have or show any Inputs (like cable box, antenna, etc). In this setup, you have to manually select the Input using your TV remote, not the Roku remote.
As far as I know, the same applies to if the Roku device (whether it’s an Express+ 3710 or 3910 model) is attached to a TV via the analog A/V ports. I have the 3910, and it is connected through my old 1991 Sharp VCR (via my old 1993 Archer/RadioShack 4-input selector box), which connects to my old 1994 Magnavox/Philips set. I don’t even have cable anymore, ‘cause we had to get rid of it back in February 2020.
