By far the winner for 30 inch computer monitors at Amazon is Apple's Cinema 30-inch HD Flat-Panel Display. Amazon has a special sale for it right now at ,752. With 47 reviews averaging 4.5 out of 5 stars, this is definitely a top choice, especially if you are a Mac user.
While it tempting to have the 30 inch screen, I do have to point out that if you can curb your technolust just six inches, you can get the 24 inch Apple monitor for nearly a thousand dollars less. You can get a new laptop for that difference. Or you could get a round trip ticket to Europe.
However, the reviewers on Amazon love the 30 inch, and they say the increase in screen size from the 24 inch to the 30 inch is a major difference. Many of the reviewers (some of them are using the Apple monitor with a PC) wax so poetic about it that you might think there was a bit more than emotional attachment to their screen going on. So if you can afford it, you'll probably love it. And hey, if your company is footing the bill, press for the 30 inch. If they're going to make you work 80+ hours a week, they should at least do something to preserve your eyesight, right?
To use this magnificent piece of technology, you will need a computer with a graphics card that can support Dual-link DVI. Some graphics cards say just "dual DVI", and those cards aren't going to cut it. In fact, just the graphics card alone is going to cost you about 0. The instructions that come with the monitor say to get a "NVIDIA GeForce 6800 Ultra DDL Card", though some Amazon reviewers have used different cards. But if you've fallen in love, then it is too late to care about the cost.
Here's the list of graphics cards that work with the Apple 30 inch monitor. If you have a PC running Windows, you'll need to get one of these graphics cards:
NVIDIA QuadroFX 2000
NVIDIA QuadroFX 3000
NVIDIA QuadroFX 3400
NVIDIA QuadroFX 3450
NVIDIA QuadroFX 4000
NVIDIA QuadroFX 4400
NVIDIA QuadroFX 4500
NVIDIA Geforce 7800GT
NVIDIA Geforce 7800GTX
NVIDIA Geforce 7800GTX 512
Apple PCs need one of these cards:
NVIDIA Geforce 6800Ultra DDL AGP for Powermac G5
NVIDIA Geforce 6800GT DDL AGP for Powermac G5
NVIDIA Geforce 6600 PCI Express for Powermac G5(PCI Express)
NVIDIA Geforce 7800GT PCI Express for Powermac G5(PCI Express)
NVIDIA QuadroFX 4500 PCI Express for Powermac G5(PCI Express)
You can skip getting the DVI cable, though. The monitor comes with it.
In addition to the massive size and the clarity of the screen, this monitor also has two FireWire 400 connections and two USB ports. That was so you can skip your computer entirely and plug right in to a printer or any other device.
