Yes. I had it installed by the Geek Squad and they asked for it right away. I had ordered a very long one (20-25’) as it had to go through the wall to where the wall mounting bracket was and connect to the cable box or something else that was not in the same location as the TV but below the tv in a cabinet.
Sorry, there was a problem. Please try again later.Sorry, I also bought an 82” TV and I needed the hdmi cable for that one. I don’t think I need an hdmi cable for the smaller one. It is not yet installed but if I needed to have that cable my son would have told me to order it so that I had everything needed for the install.
