Thanks Air_man. Yours comments are appreciated and very interesting . The Hanns was my other choice but as you can see from the above comments by Ambra4 it seems to be beaten by the Samsung on Response time and Ratio. So in my mind I had sorta made up my mind to get the Samsung. But I am much obliged for your response.
Was there not a problem with some of the Samsung SM226BW models recently, due to Samsung being unable to supply the level of demand from their regular factory. I understood that they had outsourced, and some screens were not A grade, but rather B or even C.
