I just bought a 30" Cinema Display on eBay. It is sweet. But it's an older and dimmer one. At least I'm pretty sure. I really wanted the newer, brighter one, which I thought I was getting. Am I justified in complaining about this, or should I just settle for the one I got? Let me explain. Apple released the 30" display in 2004 and discontinued it in 2010. "On March 28, 2006, Apple increased the quality of the display -- providing brightness of 400 cd/m2 and a 700:1 contrast ratio." Prior to that, they had a brightness of 270 cd/m2 and a 400:1 contrast ratio. That's about a 50% increase in brightness. Since the older ones were made for about 21 months and the brighter ones were made for about 51 months, I assume most displays out there are the newer, brighter ones. The eBay listing I purchased had "400 cd/m2 brightness, 700:1 contrast" in the summary, implying the newer one, but I'm guessing that was just an honest mistake in copying and pasting without knowing there's a difference. I asked the seller if he got it in 2006 or earlier, and he thinks he bought it directly from Apple in 2007. However, it is noticeably dimmer than my MacBook Pro's display (not sure of exact brightness on that), and it is much, much dimmer than the 500 cd/m2 monitors it will be sitting between. This leads me to believe that it's 270 nits, not 400 nits. Perhaps most telling, though, is that the bottom of the monitor says "©2005" on it. I think it's pretty safe to say that I got an old, dim one, right? I really wanted the brighter one to go with my other bright monitors. Technically, it was misrepresented in the listing. Is this a big enough issue to raise a stink about, or should I just shut up and settle for what I have? Don't get me wrong -- the monitor looks great. But if I'm going to drop a bunch of money on one of the best monitors out there, I think I deserve to get the one I want and expect. A 50% increase in brightness is pretty significant. I probably wouldn't care or know any better if this was my only monitor, but since it's next to two bright monitors, it's a very obvious and unfortunate difference. Thanks for your input. Sorry for the novel.
