If your Dell monitor's power LED is on but there's no video, try these steps: Increase the brightness and contrast in the On-Screen Display (OSD) menu. Perform a monitor self-test. Inspect the video cable connector for bent or broken pins. Ensure the correct input source is selected in the Input Source Select menu. Finally, run the built-in diagnostics.
