Windows 10 Non-existent screen

I finally force installed Windows 10 and and when I left click on the desktop and click display settings I have 4 screens. This is a problem because I only have 3 plugged into my computer.

I saw other people having this problem with windows 10. I'm quoting from user Drevik here: http://www.tenforums.com/general-discussion/9290-pc-stuck-black-screen-after-reset.html

I had three computers with this issue and spent 5 hours on it including 1 hour with Microsoft. They accidently fixed it enough for me to figure out the real problem. Windows 10 was treating our single screen computers as if they had dual monitors - the black screen was the other monitor. So ultimately, we were eventually able to right click on the screen and bring up display settings and delete the extra (nonexistant monitor). Our dual monitor computer also had a similiar problem reading three screens instead of two and again we went into the display settings and deleted the "nonexistent monitor"

You wouldn't know how to delete a screen would you?

Disable the Intel video driver

I'm having the same problem with my laptop, except the non existent display is the main display. Is there any way to move windows without being able to see them?
