Windows 8: How can I check the monitor connection when the computer fails to boot?

Last Update Date : Jan 09. 2018


If a blank screen appears on the monitor even though there is no problem with the PC power, there may be an error with the monitor connection or monitor brightness setting.

If the problem continues even after the procedures below have been completed, it may indicate that there is a hardware problem

Step 1:
If you are using an external monitor, check if the cable at the back of the computer is properly connected

Step 2:
Check if the external monitor has been turned on

Step 3:
Set the external monitor brightness to the maximum setting

Step 4:
For laptops, press the Fn + F3 key combination repeatedly to adjust the brightness
