The graphics driver uninstall tool <Display Driver Uninstaller> (DDU) can help you uninstall the graphics card from the control panel or remove the traces left by the graphics driver. After testing, it can very well uninstall the original driver in Windows 8.1, and then install a new compatible driver to unlock the black screen. (Note: DDU supports all versions of the system including Windows 8.1, but only supports AMD, NVIDIA, and does not support Intel.)

For best results, DDU will disable Windows Update to automatically update the graphics driver by default. Users in need can change it back after the operation is completed (reset the Windows Update driver installer to the default). At the same time, it is highly recommended to operate in safe mode.

There are three usage modes. It is strongly recommended to clean the driver and restart it directly. If it is not restarted, it may cause black screen and other problems. In addition, it can be cleaned and then shut down to facilitate the installation of a new graphics card. DDU recently released the latest version 9.7, recommending Windows 8.1 users who have encountered problems.
