Oops, sorry for the top post.

Just to clearify why you need to start on the TV... if, for example you set
your TV to no saturation (black and white)... no amount of tweaking on the
GPU is going to correct it.  Contrast, brightness, and color settings can
all have a similar effect... the TV is limiting whatever values you change
on the input side.
