I've recently purchased a Samsung SP46L6HX and am very pleased with it. However when i watch a program such as "Lost" I seem to have a problem with losing the edges of the picture. I only notice it when the credits come up but it must be there all of the time. I have set the tv to show in 16.9 mode and have also tried forced widescreen (or whatever its called) but still have this problem. Is there anything I can do or is this normal ?
