Recently I’ve been messing around with HDMI cables since I’ve been watching Netflix movies and TV shows on my TV that isn’t smart.
I have noticed that the cables can discern if they’re plugged in or not. If I plug in the cable with my computer off, the TV says “No signal”, and if I disconnect the cable, the TV says “Verify cable connection”. How do the device knows the difference?
I apologize for my poor English.

Closed circuits within the cable that use power from the device that tells you about the connection information and return the said info to the said device.
