Press the number 2 button on the monitor. This button changes the input selection of the monitor.
Try a different video cable, the video cable may have a problem.
If available, try another video connection. If your monitor has a different signal type, try it to see if a different connection is able to get a signal.
If your monitor is connected to a Laptop or Notebook computer, or this is a secondary display, the video output settings on your operating system may be disabled. Confirm that the display settings/properties on the operating system are configured correctly. To get to the Windows display properties, single right click on an empty spot on the Windows desktop and select Properties.
Connect the monitor to a different computer system (if available) to see if the issue is with the video card or the monitor. Check the user's guide to see if any special conversion connector or adapter is required for proper signal continuity between the video card and the LED/LCD.
