I have a Dell Inspiron 15r laptop connected to an external monitor. While installing windows 8, I had my external monitor as my default monitor. Now, in windows 8, the only monitor that I am able to use is my external monitor. The other is turned off. I have tried to extend the desktop through the settings, and it does it, because when I take a screenshot, It shows the background of my integrated monitor as if it was working fine. Its as if the monitor is simply turned off. Unplugging my external monitor does nothing, my integrated display remains off. As far as I know, it is a driver problem with dell. I know that the monitor works, due to the fact that it reaches the BIOS screen at startup. I have attempted to install new drivers from dell, however, there are none on their website for windows 8 for my laptop. Any ideas?
