I think my pen test may provide insight. Try wave a pen or similar item in from of the minitor. In many cases I notce that there is a definite strobe affect. My dad also noticed that the early mac screen sometimes appeared to flicker when seen through peripheral vision (better at detecting motion). I believe the problem may have a lot to do with the screen refresh rate, and the flourescent lights mixing and producing a low frequency (10hz?) light fluctiation that is detectable enough to cause strain. Of course I could be wrong. PS. Anyone bothered by the high pitched wines that many manitors seem to produce. >-- >Boniface Lau (613) 592-2122 ext. 3042 Boniface_Lau@Mitel.COM >Mitel Corp. >350 Legget Drive, Kanata >Ontario, Canada, K2K 1X3 -- Michael Nelson
