Dear Mr. Glynn,

Subject: Color Publishing Numbers for Dell Monitors - Macro


All Dell monitors, except one, have default color temperature as 9300 egrees
Kelvin.  (The exception is the Nokia 91862 which defaults to 7000 but you can
select 9300 via the OSD controls).


Color coordinates (chromaticity values for Red, Green, and Blue):

All Dell monitors, except one, use P22 phosphor.  The associated chromaticity
values for P22 are;

     Red    x=0.625, y=0.340
     Green  x=0.275, y=0.605
     Blue   x=0.150, y=0.065

The exception is the 21" Mitsubishi (p/n 65532) which uses EBU
phosphor.


Gamma

Gamma is dependent on a number of things such as emissions of the electron gun,
color tracking [color fluctuation due to brightness level (where the user has
his/her brightness/contrast set)], and transmissivity )contrast ratio due to the
type of CRT faceplate coating).  Depending on the age of the monitor, the setup
at the factory for that particular unit, and the users preferred
brightness/contrast settings each monitor will have it's own unique gamma
values.

If you are running Win95 it has its own color matching software.  Use the
Mnp22g15.icm file in the Windows\System\Color folder.  You can get more
information from Microsoft's web server.  The information is in Technet article
Q140902.

Respectfully,
