Input Not Supported message on reinstalling Snow Leopard

[mikethebook]

I'm wanting to do a complete clean rebuild of Snow Leopard on my Mac Mini to get rid of stuff that doesn't need to be there but when I installed the disk, clicked on Utilities and Restart the screen of my Acer V173 went blank with the message "Input Not Supported." It would go at all leaving me blind to taking the process any further. I tried reinstalling cables but that did no good. It's working fine again now with the reinstallation process unstarted but what is the problem?

Are you trying to use your Windows laptop as the display for your Mac mini? For that, you need VPN software of some sort. For VPN to run, the OS on the boot disc must be operational. This is not possible if you are installing the OS.

Not at all. The Acer V173 is my display screen.
