Calibrating your monitor

Windows 7: Control Panel > Colour management > Advanced Tab > Calibrate display.

i don't know if you clicked the links but.... there is something obvious. These pages have reference images.

"see these 3 images? OK try to remember them for the next page!" is terrible. Absolutely terrible. Noone wants to keep going back and forth between the pages, and the reference images win7 calibration uses are not that good. I will admit it is only useful if your gamma is out of whack and your monitor doesn't let you really control the gamma much.
