This a smart monitor, and you can hook your cable box, or wirelessly get video services from the internet. Mine gets the HDMI out from the cable box in our bedroom. I also get Disney+, Hulu, Prime video, YouTube and other internet providers as well. The Monitor's simple controller lets you quickly and easily switch between wireless services as well as the cable box. It does not have a HDTV tuner. You use the cable remote control to switch channels, change volume, and turn both the monitor and cable box off. We like it. My daughter likes it as well.
