The cadillac of monitor profiling solutions use a spectrophotometer to measure not just red, green and blue from the monitor, but actually record the distribution of light emitted over the entire visible spectrum.
Photographers looking for a single solution for monitor calibration and print profiling should take a serious look at the ColorMunki Photo, a spectrophotometer that does double duty.
