Question Monitor problems in editor

While I'm in the editor my monitor keeps going black and occasionally comes up with the no signal message. This only happens in Unity, all my other programs run fine. Does anyone know a fix?

 

Could be a number of causes behind this. Drivers issues, faulty video cable, bung graphics card. None of which are specifically caused by Unity, but could easily be exacerbated by Unity's nature as a program.

The easiest thing to check is your cable. Swap it out with another, see if the issue persists.
