Connecting TVs to the box

Thank you, I am trying to attach another TV to it, you are correct HDMI connected to my TV but I want to connect other TVs in my home to it.  I also have it connected directly to my router by ethernet.  My other TVs are Samsung smart TVs but when I search for directv stream it only brings up you tube directv subjects, no app.

U have to get a Dtv stream box for each tv or a device (firestick, roku, apple tv, 2017-2021 samsung tv) that has the Dtv stream app available on it.

Thank you for the info, sounds like I should just keep my FIOS and return this box.  I thought I would be able to stream everything off of 1 box without purchasing any additional equipment.

What year are your Samsung tv's? 2017-2021 models have a Dtv Stream app in their app store. You can also buy additional Dtv stream box's on for 5 dollar a month payment plans---and Ebay sells them for 50-60 bucks.
