How to fix a black screen on my INNOCN 29C1F-D when the power light is on?

If your INNOCN Monitor displays a black screen after being turned on, but the power light is on, ensure the video cable is properly connected and secure. Also, verify that your operating system hasn't entered hibernation, sleep, or power-save mode by pressing any key or moving the mouse. Inspect the video cable connector for bent or broken pins. Confirm that the correct input source is selected in the Input Source menu. You can also try replacing the signal cable with another identical one (HDMI / DisplayPort) to rule out cable issues.
