I see. I think a brightess adjustment would be more correct, dimming the green component. I am going to solve this by replacing the monitor. The greenish monitor is a Sony trinitron from Digital, while all the others are from Hewlett Packard. Because of what you say, the sixth monitor must be H.P. as well. By the way, I calculated the optimal gamma to be 1.5. > If you used no_accel, your 2D may be slow too. > -- > Dr. Andrew C. Aitchison Computer Officer, DPMMS, Cambridge Better that it works slow, than that it trashes fast. And so far, I have not seen any speed downs. Perhaps when I experiment more with 3d.
