Just returned a Samsung ue40d6530 because it had some stuck pixels. I have now had enough of Samsung because of so much recent trouble with various tv's. I exchanged it for a LG 42lw550 as the other LG I own seems (touch wood) to be a decent reliable tv. The exchange isn't avaliable for 5 days & I was wondering if I would be better off getting an LG 47lw450 for £50 more. My main concern is 2d picture quality & both tv's seem to have similair specs. I am not worried about smart tv, so was wondering if someone could tell me if there is much difference in PQ between the sets.
