Okay, here's the deal. I have a dual-monitor system with the Advanced Port Replicator hooked via DVI to a 2405FPW as the primary monitor. I have modified the color settings in the NVIDIA driver, for both the big screen and the laptop screen. When I open my laptop, it properly switches to dual-monitor mode. When I close the lid, it properly switches back to the single monitor configuration, but the color settings revert to defaults. The settings in the driver are still fine, they are just not applied to the display. Just clicking on one of the controls, without changing its value, applies the settings. The bug is that the settings don't get applied on return to single-monitor mode, even though they are still shown in the driver. This is 100% repeatable. The driver version listed in properties is 6.14.11.119. The Adapter Bios Version is 60.86.47.00.09. Control Panel version is 1.4.2.41.
