What happens if you do the following series of steps? 1) disconnect the external monitor from the laptop, allow the monitor to continue running 2) restart the laptop and login, then allow it to boot up to a stable screen 3) plug the monitor cable back into the laptop Does the monitor obtain the same image as is on the laptop, and allow you to use them together?
