Basic steps to fix black Windows 10 computer screen error

1. Black screen error during installation

If you encounter a black screen error during the installation of Windows or a new update, please wait patiently, because the installation process may be taking place in the background. However, if the time lasts from 3 to 6 hours, it is likely that the installation process has been suspended.

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

Unplug all unnecessary devices connected to the computer such as external hard drives, USBs, printers, phones, game consoles and secondary monitors.

If possible, you should also turn off Wifi and Bluetooth. Leave only the necessary connections to the computer such as: keyboard, mouse and screen.

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

If it is just a small problem or a slight problem, the installation process will continue and be completed. After displaying the Windows 10 Desktop screen, you can reconnect external devices and other devices.

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

2. Carefully check the connection cable

If your computer displays a black screen error before logging in to Windows 10, the most likely cause is a connection problem between the computer and the monitor.

In this case, if you are using a Windows computer, carefully check the screen connection cable at both ends to see if it is plugged in firmly and correctly, and is the power supply cable to the screen plugged in?

If there are multiple video output ports, you can try changing to another port. Sometimes updating drivers can cause errors such as sending video signals to the wrong port (DVI, HDMI, DisplayPort, Thunderbolt, VGA).

If your computer has both a discrete and integrated graphics card, you can switch to using the integrated card to check if the discrete card is defective. In many cases after updating Windows 10 or BIOS, the discrete card is disabled and you must re-enable it in the mainboard settings.

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

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

3. Screen detection

In many cases, black screen errors are due to Windows 10 not being able to detect the screen. You can use the key combination Windows + Ctrl + Shift + B to restart the video driver and refresh the display connection.

On tablets (such as Surface Pro), you can wake up the screen by quickly pressing the volume up and volume down buttons at the same time 3 times.

When you perform this action, you will hear beeps and activity on the screen indicating that Windows 10 can respond to the command and it is reestablishing the connection to the display.

Additionally, 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, then see if the black screen error disappears or not. (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

Externally connected devices can be the cause of black computer screen errors. In this case, try disconnecting all external devices and check to see if the error persists.

If everything returns to its original normal state and the black screen error no longer appears, then you can try to reconnect each external device to your computer one by one. If your computer has a black screen error again, then you can determine which device is causing the error.

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