Thanks, Gene. Due to the wonder of cut & paste and google, I was able to 
actually learn (sorta) what "sync signal polarity sensitive" means and why 
it would cause such a delay. The monitor is at least 15 years old and was 
cheap back then. It works great, but I could see it not having the best 
components in it.

Other than the lost left column, the picture is fantastic. Very easy on the 
eyes
I'll start looking for a suitable monitor or tv with vga input for my CoCo.
