When your computer displays a black screen, it means that the data it is trying to display is not being received. To fix your displays, you must first identify the source of the problem.
Computer Displaying Black Screen
Once you’ve ruled out a broken monitor or faulty cable, you’ll have to look deeper into the computer to figure out what’s preventing it from working.
Here are a few common causes of a screen staying black even when the computer is on.
How to Fix a Computer that Turns On But the Screen is Black
The best way to troubleshoot a computer is to start with easy fixes that only take a few moments. If these fixes don’t help restore the picture to your display, you might have to test some of your computer’s components.
One of the first things you should do is ensure your computer is completely restarted.Sometimes when you think your computer is off, it is actually still on in a low-power state to speed up startups.Powering the computer down all the way ensures that when you restart it, it’s a truly fresh start.
To restart your computer completely, press down on the computer’s power button. Hold it down for five seconds before releasing it. Let the computer fully startup before you continue troubleshooting.
Check the Connections
ensure your monitor is plugged into your video output device. Some motherboards have onboard graphics and can work without a GPU. Others don’t have graphics built into them and require a GPU to display anything.
If you have a GPU, ensure the monitor is plugged directly into it. If you don’t, make sure it’s plugged into the motherboard.
You should also ensure that all power cables required by the computer are plugged in. If your GPU needs a supplemental connection, it might prevent the computer from sending video to your display.
Sometimes the brightness on your system is so low that you think nothing is displayed on the screen because it’s not visible.
Look at your keyboard for a brightness hotkey you might have adjusted without meaning to. Press the keys to turn up the brightness while the computer is connected to a display you think is working.
Resetting the monitor will ensure that you don’t have strange settings incompatible with the computer selected.The method will vary depending on what monitor you have.
