My laptop will not work with my TV anymore (it used to). I plug it in with an HDMI cable like always but it presumably doesn't detect the TV ("no signal" appears).

This very same laptop connects to a desktop monitor just fine. This very same TV connects to a Roku box and a Playstation just fine. But for whatever reason the laptop will not connect to the TV.

I have tried extending and mirroring the display. It just does not detect the TV as a device despite the fact it used to work.

Does anybody have any idea how to fix this?
