I've tried several types of cables from dirt cheap to very expensive. I realize that the 120hz cables are just a gimmick so I never bought those. Anyhow on my hd cable box when I change the channel there's a a second and a half delay, half through the delay the screen turns bright pink and then back to black. Haven't tried replacing the cable box yet. That's the next step. Also going to try just running component cables. All the menus on cable are definitely blurred out and less sharp then before. Hoping my new purchase was not a mistake. After all I am replacing a dead rxv740.
