Dear Andreas,
I doubt that the connected monitor has 12 bit gray levels. I only know about some monochrome displays for radiologists that deliver 10bit. Maybe the system of the confocal does some contrast enhancement. Or, in case your image data are 12 bit or more in reality, the Zeiss monitor does a proper scaling from the original data to the 8bit world of the display. Did you try to optimize the scaling on your standard PC or Mac screens? With scaling I mean, how do you send the 12bit or more image data to your 8 bit world?
with best regards,
Gerhard Holst

We noticed that our confocal images look amazing (fine details well
resolved) as long as they are viewed with the monitor belonging to the
microscope, but as soon as we open them on our PCs or Macs they look just
normal (fine detail missing).
The monitor at the Zeiss mic is a HP ZR30W a pretty expensive model. It
seems to support 32 bit colours which would give 12 bit or 4096 grey steps
for each of the primary colours. Not sure if this is the secret behind the
good looking images but has anyone experience using such monitors to display
images? I would think that the graphic card, operating system and image
analysis software have to be capable of doing so, which programs would do this?
Did i miss an important development in computer hardware or is there another
reason for the amazing looking images? Any suggestions welcome.
