I ran Zorin in Live mode. Instead of totally disconnecting my second monitor I just turned off the monitor. When Zorin came up and running my monitor was GREEN. Nothing but green. And it was running the absolutely HORRID neavou driver. For the live run I do not remember any screen coming up to include proprietary software, I just said Try Zorin and it ran without any further input.
BTW I turned on my second monitor and it displays with correct colors. Just the monitor it booted up into was screwed. My main monitor.
The main reason I tried Zorin once again was because you included the 570 drivers for NVidia. But with my main monitor being green and remaining green no matter what I did it goes back on the wait and see pile of rejected Linux Distros.
