It is true that there is a difference between full screen mode and 2 inches
by 2 inches 'mode' -- there is a measureable difference. That may not have
anything to do with the problems you experienced with the Gretag software
but, in principles, full screen mode does places a higher load on the
monitor power supply than 'small screen" mode. That is what you'll find in
the display engineering litterature. Maybe that is why iMatch v2 now
displays color in full screen mode for more accurate measurements? And that
is why OptiCal is generating a medium gray full screen background to take
measurements in its smaller window. And that is why MeasureTool is also
throwing full screen black background to take measurements in its smaller
window. While OptiCal, MeasureTool and iMatch have adopted this strategy,
others like Display, ColourKit and ProfileMaker have not. It is hard to
isolate the influence of the background on the measurements but there is no
consensus among monitor profiling software maker for the moment.
I personally tend to think that this is a good thing.
