First time posting - Hope you can help.
I have a cintiq 24 running off a iMac 27"
It falls down in comparison to the Apple monitor in terms of brightness and whiteness (I can sort of live with that). But the calibration seems way off- for example when a colour is used from the swatch pallet in Photoshop its colour in comparison to the brushed colour next to it is way off (muddier/darker). When the swatch and brushed mark are moved over to the iMac monitor both colours match?????
Been through the standard calibration start up.
Am I missing some critical calibration issue here?
or is this as good as it gets for Wacom.
Your expertise would be most welcome here. Help!!
