Hi, hoping someone can help me. I have a older flat screen and I don’t know which HDMI to plug the Roku Premier in. On the back of the t.v. There are 4 HDMI PLUG IN little thingys. Output 4 through 7. Which one to plug into, or does it matter?? Thank you so much.
I've never seen any TV with more than perhaps four HDMI inputs. As long as it's an input (which is all a TV should have with HDMI), no it really doesn't matter which one you use.
Look carefully at those jacks. It's possible they aren't all HDMI. USB is similar at a quick glance, but are not interchangeable.
Plug it into any of the HDMI inputs. To view you'll have to set your tv to that same input, using the tv controls.
