Steps to fix basic black Windows 10 computer screen

1. Black screen error during installation

If you encounter a black screen error during Windows installation or a new update, please wait patiently, as the installation may be happening in the background. However, if it takes 3 to 6 hours, the installation is most likely suspended.

Once there, try turning off the computer by pressing and holding the power button for a few seconds. If using a laptop you can unplug and remove the battery.

Remove any unnecessary devices connected to the computer such as external hard drives, USB drives, printers, phones, game consoles and secondary monitors.

If possible you should also turn off Wi-Fi and Bluetooth. Leave only necessary connections to the computer such as: keyboard, mouse, and monitor.

Wait for about 60 seconds, then insert the battery and plug the power cord in and turn on the computer.

If it’s just a small problem, if it glitches a little, then the installation will continue and complete. Once you have displayed Windows 10’s Desktop you can reconnect the external devices and other devices.

If the installation process fails and returns to the old state, disconnect all external devices and try to install Windows 10 update again. Or you can use the USB Boot to install the operating system.

2. Carefully check the connecting cable

If your computer shows a black screen error before logging into Windows 10, it is most likely caused by a connection problem between the computer and the monitor.

In this case, if you are using a Windows computer, carefully check the cable connecting the monitor at both ends, whether it is plugged in properly and not, is the power cord for the monitor plugged in?

If there are multiple video output ports, you can change to another port to try. Sometimes updating the driver can make mistakes like sending the video signal to the wrong port (DVI, HDMI, DisplayPort, Thunderbolt, VGA).

If your computer has both discrete graphics and integrated cards, you can switch to the integrated card to check if the discrete card is faulty. In many cases after updating Windows 10 or BIOS, the removable card is disabled and you have to re-enable it in the motherboard settings.

If using an external monitor, you can open the monitor settings and increase the screen brightness, always check that the input the monitor is using is correct. Try connecting to another monitor or using a different cable (DisplayPort, HDMI, DVI, VGA, Thunderbolt) to see if the problem is with the monitor, video card, or cable connection.

If you are connecting your computer to the TV, double-check that the TV is turned on and make sure you have set up the correct Input to connect to the device.

3. Screen detection

In many cases the black screen error is caused by Windows 10 not being able to detect the screen. You can use the Windows key + Ctrl + Shift + B key combination to restart the video driver and refresh the monitor connection.

Try to “wake up” the screen

On a tablet (such as the Surface Pro), you can wake up the screen by quickly pressing the volume up and down buttons simultaneously 3 times.

When doing this action, you will hear a beep and the activity on the screen indicates that Windows 10 can respond to the command and it is re-establishing the connection to the monitor.

Also, assuming that Windows 10 is responsive, you can use the Win + P keyboard shortcut to bring up the “Project” menu . Then press the P key again and press the Enter key to switch between different display modes, and see if the black screen error disappears. (You will need to repeat this 4 times to cycle through all possible modes.)

If you don’t see anything on the screen, press and hold the power button for about 10 seconds to turn off the device. Then press the power button again to reboot.

4. Disconnect unnecessary devices

External devices can be the cause of the black screen error. In this case try disconnecting all external devices and check if the error persists.

If everything returns to its original normal state and no more black screen errors, then you can try reconnecting external devices one by one to your computer. If the computer gets a black screen again, then you can determine which device is causing the problem.

Disconnect your device, then restart the computer, and if the device continues to have a black screen error, contact the manufacturer for help.
