I I have a Roku Express 4K , and I am going to be giving my son my current Smart TV and I was going to get a new one. How do I hook the Roku up to the new TV? Do you just plug it in and it works since it's the Box you program or do you have to program it again?
Should just be able to attach the HDMI cable of your Express 4k to the new TV and be good to go. If your new TV is different manufacturer from your old one, may have to reprogram the Roku remote for your TV functions (power and volume).
