Recommend 27" monitor for Mid 2011 iMac

[photosmike]

I want to add a second monitor. My GPU is the AMD 6750M with 512 MB. I am into photography (Hobby) and I use my iMac with Photoshop, Lightroom and some other photo programs.

Any recommendation is appreciated.

Thanks

Mike

I bought the Monoprice 27" 1440p monitor for $299. Works for me with my Mid 2011 Mac Mini w/AMD GPU.
