Question Cannot enable monitor from settings

[Shaftyz]

So i have 3 monitor setup, 2 are same monitors and 1 is different. I went to settings, chose display 3 i wanted to disable, pressed disable and both same type monitors went black and says no input signal, tried turning it back on but it doesnt show there anymore, there is nothing in device manager too. Tried disconnecting cables etc and still nothing. What should i do?

Have you tried installing the latest driver for your graphics card and restarting the computer?
