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

Last Update date :2017.04.19




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.







When you use the computer with an external monitor,

check if the cable at the back of the computer is properly connected.



Check if the external monitor has been turned on.



Set the external monitor brightness to the maximum setting.




For laptops, press the Fn + F3 key combination repeatedly to

adjust the brightness.
