richpjr said:How do you prove, or disprove, an opinion? I think for most people it boils down to the Dell is a good monitor for a great price. The ACD is a very good monitor that costs more. Some people don't feel the difference in performance warrants the difference in price. Some do. But if I was looking for the industry leading widescreen professional display I'd be looking at Eizo, not Apple. Since I am not a professional, but merely a photography hobbyist, I'm not looking at the Eizo, but at the 2407 and 23" ACD. I'm leaning towards the ACD to go with my new Mac Pro, but may wait a bit and see how the new NEC monitor coming out looks.
Fair enough. However, the "opinion" argument is a slippery slope. You can chalk just about anything you want up to opinion, but there comes a time when you have to place value on subjective things. There are still some people who will swear until they are blue in the face that Windows is a better OS than OS X. They can pull the opinion card all the want, but there's a mountain of evidence to the contrary.
That said, The ACD is I believe a superior display to the Dell, and equivalent to the Eizo. It's subjective, of course, but if you remove price from the equation, it's difficult to argue when looking at them all side by side. The ACD and Eizo are pretty comparable, and the Dell lags behind in color consistency. Having used both in more than one environment, I have objectively viewed with my own eyes.
The one glaring difference in the specs between all three is that Apple is actually the only one with a LOWER contrast ration than 1000:1. This would seem like a deficiency, but in fact I have found in my own photography work that higher contrast monitors don't show me a true representation of my final print - they lose some very subtle blacks and whites that my ACD shows clearly.
Just my two cents. In the final analysis, none of them are bad displays in any way...
... well, except that one says Dell on the front. Sorry! Couldn't resist.
