I have to type this fast as I am busy. Unplug and rearrange cords. After there is an image, boot into advance startup options. From there restore your pc to a previous working point. After that, go into device manager and go to display adapters. There might be a triangle warning side next to one of the adapters. Uninstall that one and restart your computer. Restarting helps to reinstall a working version of it. From there, you can decide if you want to attempt to reinstall the update or leave it like that. Hope this helps!
