But, until you get manufacturers producing monitors on spec, supplying
those specs, you're not going to get true displays. Nearly every
monitor has different gamma (the trueness of the greyscale), and nearly
everybody adjusts the contrast and brightness too much. Monitors need a
light sensor, and something to compute ambient light offset against your
settings, to get true readings. It's no good trying to colour-grade
photos or printing, when your monitor is displaying black as a
washed-out grey, the monitor gamma is different from your printed media,
and the monitor has a different white tint than your paper and the
ambient light that you're going to look at it under.
Back when SGI was producing workstations with Trinitron monitors we had
complaints from PC users (probably running Windows for Workgroups) that
colors in images we produced were bad. In fact, every PC was different.
We invested in inexpensive Pantone Huey colorimeters and could show
that our PC's matched the colors on the SGI workstations. The Huey had
the ability to compensate for changes in ambient light.

There don't appear to be Windows 7 drivers for the Huey, but there are linux
drivers and associated utilities that seemed to work on a older laptop running
Scientific Linux 7. In practice it wasn't able to get the laptop display to
resemble the Apple displays we use these days, but I'd certainly try it if

I relied on linux and had a decent display to work with.
