"The instructions I would provide to the end-user once I confirmed the problem and that they have access to their computer would be as follows:
Press Windows Key along with P to launch the project menu.
Make sure the display settings accurately reflect the configuration for your computer.
Press up and down arrows a few times and hit enter.
If it works, you will be able to see your screen. If not, repeat this step a few times.
If you have a password-protected account to log in, press CTRL or space enter the password and hit enter. It might take you a few trials before you succeed.
If this process didn't work, then they may have to uninstall the graphic card driver. At this point, I would remotely log in to their computer so that I could execute the updating of the graphic card driver since most users do not have the background required to perform this process."
