Answer 1

when you connect it to your hdmi cable, why are you connecting it to your laptop?

Answer 2

Answer:

Make sure the TV is set to the correct video input to receive the HDMI signal. Most TV remotes have an Input button that cycles from one input to the next. Press the Input button repeatedly until the correct HDMI input is displayed on the TV. Be sure to check which input on the TV you are connecting to.
