I've just bought a Quato IP240LE monitor, with hardware calibration support.
Unfortunately the iColor Display software does not seem to work with my graphics card, an ATI Radeon 9600 Pro (AGP slot, Mac G5 2.5Ghz). It works fine with my MacBook Pro's Geforce 8600.
I wondered if anybody has had, or heard of issues with DDC/ic support from this card. Quato support thought it should work, but have not tested it. My only alternative seems to be a very expensive (not to mention rare) Nvidia NV40 6800 GT (love these product names...) so before I take that step, it would be nice to get some conformation that the ATI is a dead end.
Actually, I have software-calibrated the Quato for now, using a ColorMunki, and the print matching is already fabulous :-) Quato tech support also tell me I can copy the profile created on the MacBook to the G5, so maybe I'll try that.
