Yeah, this 'vibrant color' issue is one of the main reasons why I kept putting
off the purchase of my first flat-panel monitor years ago; my older CRT monitors
(of which I still have ONE working model, thankfully) just looked more 'natural'
to me. And still do ;-)
As to iCC profiles and other assorted goodies...
My Win 7 computer has a built-in graphics chip: Intel Q965/Q963 Express Chipset
family. (I've never installed a 3rd-party graphics *card* on any computer, BTW.)
From some research I've done, Windows (starting with Vista) began using its own
color gamut-mapping feature or converter, called WCS (Windows Color System). In
Win 7's own "Color Management" app ('advanced' tab), these are the various
parameters I see:
Rendering intent: I set it to "Perceptual (photo images)"
ICC profile-- apparently only one is installed on my computer (or none at all?):
"sRGB display profile with display hardware configuration data derived from
calibration."
Device profile: "System default (sRGB IEC61966-2.1)"
Viewing conditions: "System default (WCS profile for sRGB viewing conditions)"
And, in the "ICC Rendering Intent To WCS Gamut Mapping" section :
Default rendering intent: "System default (perceptual)"
Perceptual (photo images): "System default (photography)"
-- (the rest of it looks to be unimportant, for my usage; all are system
defaults)--
Does all of this make perfect sense to me? Well... :-( I guess I should try
and find an iCC profile for my specific monitor, as you suggest.
For rendering POV-Ray scenes, this is my current set-up:
monitor at its native resolution -- 1920 X 1080
Display_Gamma = srgb
File_Gamma=srgb
assumed_gamma 1.0
