Setup Guide · How-to
Which port is the TV listening to? The input button answers it — match the list entry to the label printed beside the plug.
Every external device — streaming stick, cable box, console — plugs into a numbered HDMI port, and the TV can only listen to one port at a time. Choosing the input is telling the TV which port to listen to. That is the entire concept; the rest of this short guide is the practical detail that makes it boring forever.
This works the same way on every brand of TV. Compiled from TV manufacturers’ documentation.
Look at the back or side of the TV and read the tiny label next to the plug: HDMI 1, HDMI 2, and so on. This thirty-second habit prevents nearly every “no signal” moment later. If one port is labeled ARC or eARC, leave it for a soundbar — the HDMI explainer explains why.
The button may read Input, Source, or show a box with an arrow. A list of ports appears; highlight the one you noted and confirm. Give each selection two seconds — devices take a moment to wake their picture.
Many TVs let you rename inputs (“CHRO—” becomes “Streaming stick”). If your TV offers it, renaming once means never counting ports again.
If this stage fails: If the list shows the port but the screen stays black, the device itself is asleep or unpowered — wake it with its own remote.
No signal is not an error; it is the TV saying “this port is quiet.” Either the input does not match the port, the cable is not fully seated, or the device is off. Check in that order — the match is the usual story.
A picture that appears then vanishes after a few seconds is a different, rarer creature: often a cable that cannot carry the resolution being sent. The included cable from the device box is the right test.
If this stage fails: If nothing brings a picture on any input, the device maker’s setup pages for your model are the right next stop.
