When I was first using two ACD monitors, I was reasonably happy with the calibration I got from the Monaco Optix Pro software. I never got perfect match to my prints, but then I had a low-grade printer so I didn't expect a lot more. Later, I upgraded the printer and Mr Rodney made me an excellent profile, which enabled me to see that my monitor calibration was off. I bought BasICColor which gave me profiles that were a far better match to the print, and I finally had excellent monitor to print matching.
I replaced a dead ACD with the Eizo CE210W which meant I also had to replace my video card, so all was sent back to square one. Initially I calibrated the Eizo with it's own software, and it looked fine to me, but the ACD looked quite different - just a matter of re-doing the Apple, I thought. In the meantime I hadn't used the monitor for photos, I've just been working at my day job. When I finally got round to evaluating it properly, I could see that my initial non-critical impression was quite far off. The ACD was actually still pretty good using its old profile, but the Eizo was not good.
I've since manually adjusted the profile from within the BasICColor software and it now is a closer match, but not good enough. I'm struggling to know where I go from here.
BTW, I examine my prints under controlled 6500k lighting
