Alienware X51 Black Screen After Windows 10 Upgrade

Alienware X51 systems may experience a blank screen with only the mouse cursor after upgrading to Windows 10. This happens because the video card driver assigns a monitor to each video output even if a monitor is not plugged to the card. This assigns the HDMI port as the primary display, if you have the screen plugged to the DVI or Display Port outputs the driver will show you an extended desktop.

Supported Systems:

• Alienware X51 R1
• Alienware X51 R2

1. If you are using a DVI or VGA monitor try to connect a HDMI display to the system
2. If you are using HDMI already try to use another available HDMI port on your system
3. Press the Windows Key + P 3 times and press Enter.
4. If all the previous steps fail, press the power button, wait for the system to shut down and turn the system again
5. Download and install the latest driver from AMD or NVidia.
