Same here on a Samsung P2270HD that I got me recently. I'm not sure but I think it might still be outputting 50Hz despite the display saying 60Hz, as scrolling seems smoother than if I select 60Hz from the Indivision (which displays fine). I wonder if this could somehow be helped from the indivision end, as it seems to be an issue affecting a range of display devices.
