If your Dell Monitor has no video but the power LED is on, try the following: * Increase brightness and contrast controls using the OSD. * Perform a monitor self-test feature check. * Check for bent or broken pins in the video cable connector. * Run the built-in diagnostics. * Ensure the correct input source is selected via the Input Source menu.
