Windows 7 after installing the video card driver The monitor is black screen on the Windows login interface

If you are installing a graphics driver and you encounter a black screen, check to see if you have two display devices plugged in.

This is the thing.

Bought a win 7 from the Internet today and spent the night installing it. After installing the video card driver, the monitor will be directly in the Windows Landing screen black screen, can hear the Windows landing sound

Keep trying in safe mode, or not.

Later, I tried to blind the password in the Black screen interface, actually went in. A look at the display settings, is the video card then the TV is set to the first monitor

I reset the computer monitor to the first monitor, solve the problem!
