A:Answer Hi Flojo. The Spectrum app is not compatible with the webOS 22 TV Platform (Operating System) that this LG 65 Inch Class B2 OLED 4K UHD Smart webOS 22 w/ ThinQ AI TV, Model # OLED65B2PUA runs on. So if you are looking to download and install the app on the TV, you cannot, it is not available for download and installation on our TVs. Apps does not download and install via HDMI. Compatible apps can only be downloaded and installed on our TVs through the LG Content Store (App Store) feature on the home screen on our TVs. If Spectrum is providing you with a cable Set-Top box for their services, depending on what connections their Set-Top box has, you can connect it to the TV's HDMI ports or to the TV's F-Type, 75-Ohm, Coaxial connector on the back of the TV labeled 'Antenna/Cable In'...^Ivan
