Good morning Edmund and Jack:
Once again, I thank you for your responses. My graphics card was just upgraded to handle the resolution of the Eizo; it is an ATI Radeon 9600 Pro for Mac/PC. Eizo says the 9600 Pro is compatible and this card is a recent upgrade from the latter model. As Jack states, the resolution (not the monitor name) is listed in the Display tab (1900x1200). Also, as Jack so clearly stated, a major selling point for me was the Color Navigator software, which does the calibration in the monitor itself, bypassing the video card. (I hope I said that correctly). I just don't understand what could be the issue but bypassing the calibration software would definitely be a solution; yet, in my personal opinion (financially influenced, of course) would not justify the price of an Eizo. I have not read of anyone having this issue, so as of yet, I don't know what is preventing the software from detecting the monitor. I'm not that knowledgeable so I am sincerely grateful for all your input.
