Could check your settings under "screen resolution", might have to reinstate the second monitor or, very well could be a driver problem with your display adapter so could try an update (if available) from manufactures site, had two machines claim Win 10 couldn't be installed because of incompatibilities with their graphics adapter, gathering it's becoming a common issue especially if the manufactures are lagging in providing drivers for 10.
