Something I forgot to mention is trying the monitor's built-in balance controls too.
I mean no offense but the Spyder4 looks more a way to make money than be helpful. I do a bit of photography and generally the prints don't look much like the display does no matter how I tweak the settings. Then there's the paper, ink, and printer all conspiring to make a good shot look crappy.
I think the Spyder would be as useful as one of these.
