Any difference in Cinema Displays based on age?

I'm looking at getting a 23" Cinema Display to go with my Macbook. Are there any differences in say a display produced last month vs. one produced 1.5 years ago? Any component upgrades or the like that would make buying an older display not a good idea? Thanks for any information you might have.

Yes, the 23 & 30" displays received a "silent upgrade" late 2005, along with a price drop:

The specs on the 23" went from:

Brightness: 270cd
Contrast: 400:1

to

Brightness: 400cd
Contrast: 700:1

So there would be quite a noticeable difference...

Thank you! That is the exact kind of information I was looking for.

It's hard to believe they haven't come out with built-in iSight or additional ports like Dell. Honestly, I'm amazed when I see a person has bought one. The Dell Ultrasharps have the exact same LCD screen, (and I mean same maker, not just same specs) plus more available ports at a lower cost.

I think we should see Steve announcing new LCDs with more ports and iSight at WWDC, but that's a conversation for the rumors thread.

I don't know if that is true in real world usage. My friend has a Dell and an Apple side by side, because he could not afford another apple when he went to get a new screen, and you can see the difference.

I honestly don't know how unless the computers they were attached to had different video cards or different display settings.

I've read quite a few reviews from reputable tech reviewers. None have found any appreciable difference in the display. One even busted open each one and the only differences he found was the additional hardware in the Dell for the ports.

Even if you could see the smallest difference, is it worth $300?

probably not, but i went with all apple displays to keep everything matching. If I had to do it now I might go with dells, (i just bough a apple display yesterday, but if i had to buy all new stuff) because I hear they are the same and I kinda like the black look.

I'm waiting to see if they release a new cinema display @ WWDC. There have been price drops on apple's site so I guess I'll have to be patient. I really want a 30" badly.
