i know every time you look for "how to calibrate my monitor's colors" everybody comes out the woodwork saying how you absolutely CAN NOT do that without a hundreds-of-pounds-cheap colorimeter device or whatever but like how come we can't have the subjective gamma adjustment screens like mac os x had in 2003
my ibook g4 from 2005 is one of the best calibrated computer screens i own simply because there is a feature to adjust the colors by eye built into its operating system
