I witnessed severe light flashing from the bottom edge lit Samsung KS models at the Best Buy. It is really distracting in dark room setting as it was being displayed. I noticed that there was no mention of that in the review. For me this is a dealbreaker as the room I will use this will be completely dark. This is particularly bad with the black bars and this samsung model being bottom edge lit doesnt have the option like the JS series to keep the bars dark.. Is this something Samsung fixed after shipping the show room models?
