Can anyone recommend a good monitor for editing D600 photos?

i don't know what everyone else has replyed to you, but i would get a 32" LED 1080P TV instead of a PC monitor, they cost a lot less now, and you have more flexibility with a bigger screen because you have more room to blow up the photo more, plus you can connect your cable box or whatever to it to watch TV, since is a TV. Computer monitors cost more, plus you have to buy a separate TV tunner. I would get either Samsung or Sony.

I have a Samsung 32" 720P LED TV.  Is Just a suggestion
