Dell ultrasharp U2212hm with imac

Hi all,

i was using a 2006 imac (matte screen) for years. it has now gotten slower

so i bought a 2010 21.5" imac but the screen is too glossy for me (i'm a photographer)

I have a budget, i know its an older monitor but is anyone using or has used the Dell ultrasharp U2212hm 21.5 inch

monitor with an imac, and is it a matte monitor?

21.5 inch is what i need and must be matte.

appreciate it.
