Can't change desktop color settings

[Captainmk]

I have this pathetically stupid problem with the nvidia control panel.

I have a second display configured (my tv) and I'm trying to change its colour settings but it's not registering at all. When I click "save" the settings just jump back to default and the radio button switches back to "other applications control settings" rather than "use NVIDIA settings" which is what I want.

Any ideas on this ridiculously annoying problem? I am using Vista Ultimate 32bit and I have the latest nvidia drivers.

You can't control the TV 's color from the computer, unless this TV has computer inputs other than the standard RCA inputs. How are you connecting this TV?
