I bought a Colorvision Spyder which should make it possible to adjust the color of a CRT or LCD screen. I used it on my PB 867 and got a problem to adjust the RED color. I asked the support people and I got the answer that for a 2 year old PB it will not work. One must be able to adjust the RGB of the monitor via different dials for each color. That's 140 Euro (not Euros - it's always without "s", but nobody does) down the drain. Paul Moortgat
