Hm.. why should you have noticed the effect on the VW222S? Does it
happen there too?

I attached the xrandr --verbose output and the
# get-edid | parse-edid
output from http://www.polypux.org/projects/read-edid/ which I already
had installed. Hope this works for you too.

Yes. I'm not shure how this could happen. It probably is either a bug
somewhere, or it is the 'natural' effect of misconfiguring the vga
pipeline. Maybe someone more knowledgeable than me could make a more
educated guess about this.
