Sorry to hear that it's not working for you. I'm not surprised that the old CRT isn't compatible, but it could have worked with the projector. I looked at the manual for the W6000, unfortunately I couldn't find anything on DDC/CI in there so I think you're out of luck on that front. Didn't the projector come with a remote?
As for creating brightness/contrast profiles for nVidia Control Panel, I don't think I've heard of any software that does that.

I play games. In addition to my PC, I own a cosy collection of consoles including GBC, PSX, GBASP, PS3, GCN, X360, NDSiXL, Xbox, PS2, Wii, Dreamcast, PSP and PS Vita.
