Verison is my cable provider. I recently purchased a 4K Samsung Smart TV. The problem that I was having is that there were black bands (about 2 inches) below and above the picture when I looked at FIOS cable channels and also when I looked at a movie from a blu-ray player. Samsung was able to fix the blu-ray problem by adding a MOVIE option to the TV. But, I still can't get the cable channels to completely fill the TV screen. I am wondering if this is due to the fact that Verizon doesn't provide 4K signals. Anyone else have this problem?
