Really, the main thing that causes lack of good colour rendition in monitors is the particular colour phosphors used (whatever the type of display). If you don't use pure red, green, and blue, but un-pure/pale imitations, as many monitors to, you can never get accurate colours. For example, any attempt to show red gets displayed as orange/red or pale pinky/red, and since red is a primary colour (of additive mixing), there's no other way to get red than to have the single red phosphor be accurate, to begin with. Likewise with blue and green, they're the other primary colours of light. All other colours are made by mixing. It always gets me how some display manufacture likes to say that their display shows a wider gamut for some bogus reason, such as having a brighter display. All a brighter display lets you have is the potential for more different steps between fully black and fully white, you can't get a more red, or more blue, or more yellow, or more anything, than the actual colours the phosphors radiate at. Way back when (years ago) I used some screen to printer matching technology, so that printouts turned out as you expected them, it really annoyed me that it worked by further messing up the printout, rather than modifying the display to emulate the printout, so you could really see what you were going to get. 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. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
