thanks for the reply :)

the La Cie Electron Blues are CRTs. the problem i am having is that the 
target provided by the Spyder software for the brightness setting 
remains totally black whether i set the monitor brightness to 1% or 
100%. there is no gray differentiation in the squares at any point. in 
the Spyder Help files it is indicated that this can be a problem and it 
is best to default to the factory settings for the brightness, in this 
case the resetting of the brightness defaults to 30%. i continued on 
with the calibrations, adjusting the RGB sliders and so forth, to the 
completed profile. the result was that all dark gray areas and shadows 
were converted to flat mid gray tones. for instance the software 
preview window of the before and after view of the completed profile 
showed that the new profile was not producing blacks very well. shadows 
are washed out gray fields. the same was for the drop shadows on the 
OsX interface windows and text, just neutral shadows and lousy 
feathering.

i decided to recalibrate the monitor again but this time i set the 
brightness up to the 100% point instead of the default 30%. the result 
is a nice bright profile with good blacks, sharp black drop shadows 
with smooth feathering. but although it looks nice i don't know if this 
is the optimum brightness setting for proper color values and gray 
scale.

i was just wondering if anyone had experience with the Spyder Software 
and La Cie CRTs and find out how they resolved this.
