I happen to be a fan of NEC monitors from way back. The image color has always
seemed to me to be broad and accurate.

The first NEC I got came with a calibration device, and it was a great
innovation that simply didn’t stick. At the same time, I think that most quality
monitors (generally name-brand) will be more than adequate with proper
calibration. Several things that I consider important to note about monitors are
the dot pitch (anything around .22-.25 for the larger monitors is very good),
and the darkness of the screen (as well as glare reduction). The latter is
important as if the screen isn’t dark when it is off, it most certainly won’t
get darker when you turn it on! A dark monitor is necessary for displaying
accurate shadows.

Another important thing is your graphics card when you have a monitor of this
size. You will need some extra processing power to be able to have a high
refresh rate. I prefer ATI cards because I have had good luck with them, but,
again, other companies make excellent cards.

Another option to consider is dual monitors. I have some additional information
