Digital BW, The Print

My monitor is a NEC Multisync FE950+.  When I calibrate with my 
Monaco 2.1 and Monaco Sensor Colorimeter, Win 
XP home, the monitor does not permit any adjustment to the default 
setting of 6500K.  That is, you can't adjust brightness and 
contrast.  I have been using 7500K as my standard, but I wonder if 
it would make sense to have 2 standards: 5000K for "natural" finish 
paper and 7500K for the "bright whites."  I use 2.2 as the gamma.
