Why does my monitor keep going black? | A troubleshooting guide

If your monitor keeps going black, it could be caused by a few different things. In this troubleshooting guide, we’ll help you identify the cause and find a solution.

First, let’s rule out some common causes that aren’t related to your monitor:

  • If your computer is connected to an external display, make sure the display is turned on and set to the correct input.
  • If you’re using a laptop, make sure the lid is fully open. Some laptops have a setting that causes the display to turn off when the lid is closed.
  • If you’re using a desktop computer, make sure the monitor is plugged into a power outlet and turned on.
  • If you’re using a laptop, make sure the power cord is plugged into the laptop and the other end is plugged into a power outlet.
  • If you’re using a desktop computer, make sure the monitor is plugged into the computer’s video port. The video port is usually located on the back of the computer.
  • If you’re using a laptop, make sure the laptop is plugged into an external power source. Some laptops have a setting that causes the display to turn off when the battery is low.

If you’ve ruled out all of the above, then the issue is most likely with your monitor. Here are some common issues that can cause a monitor to go black:

  • The monitor is turned off: If the monitor is turned off, it will appear black. To turn on the monitor, press the power button. The power button is usually located on the front of the monitor.
  • The monitor is in standby mode: If the monitor is in standby mode, it will appear black. Standby mode is a power-saving mode that turns off the display. To wake the monitor from standby mode, press the power button. The power button is usually located on the front of the monitor.
  • The monitor is not receiving a signal: If the monitor is not receiving a signal, it will appear black. The most common reason for this is that the cable that connects the monitor to the computer is not plugged in. Check that the cable is plugged in to the video port on the back of the computer. The video port is usually located on the back of the computer.
  • The monitor is not compatible with the computer: If the monitor is not compatible with the computer, it will appear black. The most common reason for this is that the monitor is not plugged into the correct video port. Check that the monitor is plugged into the video port on the back of the computer.

  • The monitor is defective: If the monitor is defective, it will appear black. If you think the monitor is defective, contact the manufacturer for troubleshooting and warranty information.

If your monitor is still going black, there may be an issue with the computer. Here are some common issues that can cause a computer to not send a signal to the monitor:

  • The video port is not working: If the video port is not working, the computer will not be able to send a signal to the monitor. The video port is usually located on the back of the computer. To test the video port, plug a different monitor into the video port. If the other monitor works, the video port is working. If the other monitor does not work, the video port is not working.
  • The video card is not working: If the video card is not working, the computer will not be able to send a signal to the monitor. The video card is usually located inside the computer. To test the video card, plug a different monitor into the video port. If the other monitor works, the video card is working. If the other monitor does not work, the video card is not working.
  • The computer is not turned on: If the computer is not turned on, it will not be able to send a signal to the monitor. Make sure the computer is turned on. If the computer is turned on and the monitor is still black, the issue is most likely with the monitor.

If you’ve tried all of the above and your monitor is still going black, the issue is most likely with the monitor. Contact the manufacturer for troubleshooting and warranty information.
