You also may want a monitor with high contrast.
I remember when I bought my 30" monitor ten years ago people advised me to get one with low contrast, supposedly because editing images on high contrast screens makes soft proofing for print difficult, since printers have much lower contrast than LCDs.
At the time, they recommended a 500:1 contrast ratio with 1,000:1 being the highest. In hind sight, I wish I bought a high contrast monitor instead because my printer (Epson 3800 at the time) consistently produced greater shadow detail than my 1,000:1 monitor ever could (the opposite of what you'd expect).This frustrated me to no end. I concluded that my monitor's native contrast was considerably lower than its official specs claimed. Next time I'm going HIGH contrast no matter what they say.
