A:AnswerHey Walt. You can use three different devices for each HDMI port. The only thing that concerns me is if your sound bar is on the third HDMI port and you want it to be used with the #1 or #2 devices, you may need some type of adapter to add the sound bar to the other ports.
A:AnswerYou have to click from the Samsung menu Home > Settings > General > External Device Manager > HDMI UHD Color and then select your HDMI connection.
A:AnswerI would suggest you try adding to your cable line to TV a signal amplifier. It may surprise and correct your lost signal. Cable does deteriorate over time.
