I created a color profile for my monitors, which has worked fine with Windows XP, and Vista with a ATI graphics card. I built a new system with a Nvidia card and moved the color profile to the new system. The color profile on the Vista system with Nvidia card never kicks in when the system is started. Have gone through the Nvidia control panel and can fine nothing on color management. Since all my photos are based on this color profile, they pretty much look like crap when viewed on the monitor. Suspect the Nvidia dirver is the problem, but even the latest version is not allowing the color profile to work. Any ideas would help.
