I have a late 2012 Mac Mini, Ivy Bridge, connected to a 24" Samsung LCD dsplay,using the HDMI to DVI video cable that came with the Mac Mini.  At random times when I am doing something or browsing the web, the screen will go totally black and then revert to the proper display.  This Mac Mini is connected to a 2 port KVM, however I never see this behavior when the KVM is switched over to the PC.  Has anyone else seen this behavior?

Mac mini, OS X Mountain Lion (10.8.2)
