The LW acts fairly smooth, however, the side black borders bulge markedly inward. That's with us not so bad, as we do not take full advantage of the 2 m wide, in the first test I had a good visual impression.
Update, 21/12/2012:
We just watched a movie with lots of snow landscape. Almost white background light horizontal stripes are visible, so there is also in the middle range light waves. I have no comparative figures with other products, but would like to mention this for completeness. Knowing this and look carefully, it can be annoying bissl. So I subtract a star. But still we have a huge gain over our previous workaround. The arches on the sides are relatively strong, but not interfere with us as we do not take advantage of the full width. The LW is otherwise after only one day was just the hour taken off, almost completely transpired. Until now I do not regret the purchase because I think that you can not get for the price. If it stays that way, the LW is for the price perfectly fine.
