Monitor configurations can cause no boot situations. Check for the following:
- The monitor is plugged in and turned on.
- The video cable is connected properly at the monitor and the computer.
- Be sure to select the correct input source, if the monitor provides multiple input source types. Examples: VGA, HDMI, DisplayPort.
- Check the brightness and contrast controls.
- Check the status indicator light on the monitor:
- A green light indicates the monitor has sufficient power and is getting a video signal.
- An amber light displays if the monitor has power but it is not getting a video signal from the computer. The problem is likely in the computer.
- If the light does not turn on at all, it can be a problem with the monitor itself. Make sure that the monitor is connected to a working AC outlet. If there is an on/off switch for the outlet, turn the switch to the on position. If the problem persists, try the monitor on a different AC outlet or a different system, or replace the monitor.
