Disabled Monitor in Device Manager. help!!

[Witchdump]

So I went into Device manager on my desktop and I disabled the display on my monitor. I only have 1 monitor and I disabled it. And I don't know how to change it back since I can't see anything on my monitor it just keeps going into sleep mode when I try to turn the monitor on. Please help.

Boot into safe mode and re-enable it.
