There have been some previous threads on this subject which it maybe worth searching for to get a wide range of opinion.

My own personal opinion is LCD monitors are first choice.  They are easier on the eye, use less power, take up less space, produce a wider colour gamut, more widely available, etc etc etc.

For maximum detail look for resolution and pixel pitch . At sensible prices you won't find better than the Dell 20" ultra sharp

For maximum colour gamut you won't find better than the Samsung XL20 Blu LED  monitor if you have the budget to go that far. 

My own personal choice ?    Well I like the wide screen and have a Dell 24" wide screen ultra sharp, a compromise between resolution and wide screen at a reasonable price.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
