In general, if you are experiencing any quality issues with your cable, it may have gone bad. However, sometimes it’s just a matter of making sure the inputs are plugged in correctly to get it to work. If you have checked that and still experience symptoms, then you may need a new HDMI cable.
Why did my HDMI cable suddenly stop working?
The most common course for a problem is a bad connection between the HDMI cable and the device. This is common if you are plugging and unplugging the cable regularly.
Why does my monitor say no signal when HDMI is plugged in?
Why does my HDMI 2 say “no signal?” Typically, a monitor displays a message “no signal error” when there’s a problem such as a loose cable, loose connections, or a problem with the input device. Graphics driver and output resolution problems can also cause this error.
