You will be able to completely eliminate the vertical lines with the forthcoming config tool, as that will let you configure the output mode to a Vesa standard. The sampled pixels of the flatscreen will then be "on the spot" where Indivision AGA MK2 produces them, and you'll have a crystal clear picture. That same crystal-clear picture is already possible if you're using the DVI connection - a purely digital connection does not require any sampling and thus doesn't have the artefacts that come with sampling.
