I'm certainly not an expert on this subject, but I just can't see how 'eye persistence' has any bearing on the matter. Its the "now I'm here", "now I'm not" attribute of an interlaced display that causes the flicker, not the physiological response of the eye to color. >Adding a greenish cast >causes noticable flicker much sooner than does adding red or blue. This makes sense. The Green phosphor has a shorter persistence than either the Red or Blue. (Can't remember where I read this though) >/kim -- Richard J.
