For the past year, I have been shooting primarily with a Nikon D800e and a Hasselblad H4D-40.  Both of these cameras are relatively high megapixel cameras (36 and 40 respectively) and allow for large beautiful prints.  The "problem" with making large prints is not only are they expensive, but imperfections in the source image become more apparent.  You also start thinking more critically about brightness and color as you spend more money on larger prints (for yourself of for clients).  

I've always liked the Cinema Displays from Apple.  I have two older 20" Cinema Displays, one 24" LED Cinema display, and one 27" Thunderbolt Display (NOT to be confused with the 27" Cinema display, which connects via mini-display port ant lacks thunderbolt).  The monitors themselves look sharp from a form factor perspective and always display rich, vivid, colors.  There are a couple issues I have with them though.  Lately my issues with them are growing and growing.  First, they are expensive.  Second, they lack modern connectivity.  The Thunderbolt display does in fact have a thunderbolt port which is nice (and I believe at the time of writing is the only thunderbolt monitor on the market....LG announced one at CES back in January but it has not been released yet) and allows for the monitor to function as a dock so to speak, but the inclusion of USB 2.0 ports vs USB 3.0 ports is ridiculous.  Third, I always find that they have a slightly yellow/greenish tint to them.  The 24" Cinema Display I have I even had Apple replace the display because of the tint issue at a cost of >$600 (thankfully it was under Applecare and I didn't pay a dime).  Last, they are very reflective...I find it hard to do some things in lab with my 24" because of how reflective they are.  

For all of the above reasons I looked into different monitors for my new 2013 Mac Pro.  I wanted wide color gamut monitors with a matte display and even backlighting that were amenable to calibration.  I found two that really peaked my interest: the NEC PA272-BK-SV and the Eizo CG277.  In the end I went with the NEC simply because it was cheaper (and on sale when I bought it...the Eizo is BRAND new but I expect prices to come down in the future).  Unlike the Eizo, it has an external calibration sensor (basically an NEC-branded X-Rite i1display pro from what I can tell), but otherwise shares similar specs.  So far I really like the monitor.  It plugs in to the Mac Pro with a [supplied] mini-display port to display port cable (mini-display port plugs in to thunderbolt port on mac, display port plugs in to monitor).  After plugging it in, installing the supplied SpectraView II software, and plugging in the [supplied] colorimeter, I had it up and running and calibrated in about 5 mins.  Very quick and painless.  So far I'm a big fan!  I was hoping I could use the supplied software and colorimeter to also calibrate my other displays, but unfortunately only certain NEC displays are supported (minor bummer).  The only other downside is that I imagine I will have to run a USB cable from the monitor to the computer if I want to use any of the USB ports (also USB 2.0 unfortunately) on the monitor itself.  I will amend my thoughts in the future if I experience any issues.
