What Screen Res You running!

[dejaVu]

I don't think so, but maybe you are right. I tell you what. Open MAX, and go to preferences and set the gamma (according to max), with the gray box inside the stripped box. Then move your head just a little to the left and a little right. You will see that the gamma shifts radically. While your Spyder can calibrate your LCD for a dead on straight look at your monitor, can you garantee that that your head will be placed in front of your screen exactly that way?

Yep...the only bits that move when I'm working are my arms and eyeballs.
Head usually dead on facing the screen.
