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.

It’s like shaking hands; if you hold out your hand to someone, you’re expecting a physical connection with the other person’s hand. If you’re not holding his hand yet you’re not “receiving a signal”. When your hands lock, you are. Same goes for cables. The output device, like a monitor or TV expects a signal from the connector your monitor/TV is set to (AV input). As long as nothing’s plugged in, it will show “no signal”.
