After the monitor is changed, the original resolution of the system is too high, so that the black screen of the monitor cannot enter the system. What should I do?

This problem is often encountered. You can change the monitor and then change the resolution back to the monitor. However, this method is quite practical and troublesome. Here is a simple method:

1. Most people can think of entering the safe mode, modifying the resolution, and then restarting. This is useless. It has been tested several times. MS is used to modify the resolution in security mode.

2. The correct answer is: Press F8 to enter the VGA mode. In this mode, modify the resolution and restart. OK!
