The install script need to have the 'script' box ticked for it to work.
Giving it a quick once over with my new Samsung monitor, (which I hadn't got around to testing till about 5 minutes before I saw the updated config tool and which didn't have any display on HDMI for the Xtreme super-high res display) after using the tool, seems much better, no lines at all with Xtreme 1280 x 1024, games take a few seconds to adjust screen but couldn't see any lines.
I shall do a bit more testing before I go to bed.
Edited to add dvi not Hdmi, darn confusing new fangled terms, etc etc
