Thunderbolt display grainy

I recently purchased a 27inch TBD. I have my 13in macbook air connected to it. 1.8 GHz Intel Core i5 running OS X. I have the display resolution running at 2560 x 1440. I'm not mirroring lid is closed. My issue is when I look at pictures and movies. The display is grainy and the color is off. I've played with different settings and it's still looks the same. I was wondering if anyone has run into this issue. Or if maybe i have a faulty TBD. Thanks for the help
