OK what should the refreshrate be set at then and why :blushing:

Well, 60Hz in a computer screen is on the edge of perception looking straight on you can't really see it, but from the corner of your eye you probably can. While you don't consiously see it, your brain still registers it. This causes headaches. Now with TV's the glow time of the fosfor is longer so it doesn't flikker as much, plus it's interlaced (which means half the picture is visble at any given time) that helps alot. With TFT's you don't really suffer from this because the pixels stay lit until changed. As opposed to a fosfor pixel on a CRT that only glows briefly when the beam hits it.

With CRT's you need at least 75Hz, preferably higher 85 or 100Hz suffices if your CRT can handle that.
