What I mention, are the reasons why a 48" works for me. Doesn't work for you? Cool, no problem, they offer a 40". Wonderful to have choice isn't it? That way we can all be happy.
Point in this remark was that into discussion on strictly technical issues you introduce arguments which are not related to it. Your arguments are fine but they can not be compared with technical arguments.
What it appears now is that Samsung TV is fine as computer monitor and compares very well with the genuine Philips 40" monitor. They even have similar problem with shadowing. The major difference inidcated until now is Samsung is more glossy. But Samsung is curved and that is what keeps me happy when seeing confirmation there is no way back from curved shape.
