Hehe, yeah, lived in Europe for years and swear I could see the 50hz lights in the ceiling flickering...of course the more Bock beer I drank the less noticeable it bacame. OK, I'm surely not a video/monitor guru, but to add (or attempt to add something) to the info (I'm going on memory since I don't want to read the whole thread again)...interlaced and non-interlaced monitors will also make a difference in screen flicker (I think). One other thing, and this comes from the complaints of customers I serve out of our IT shop...flicker seems to show up best on a full white background. At least that was a major commonality in the complaints we received. So, possibly look for flicker with that kind of screen...not one filled with different colors.
