To adjust the brightness and contrast, press the menu button on your monitor to access the on-screen display (OSD). Navigate to the brightness and contrast settings using the arrow buttons, and adjust the levels according to your preference.
A "No Signal" message indicates that the monitor is not receiving a video signal from the computer. Check that the video cable is properly connected and not damaged. Make sure your computer is powered on and not in sleep mode. Verify that the correct input source is selected on the monitor.
