Hello Everyone, just purchased a brand new 65 Samsung 4K UHD and have an Arris VMS1100 cable box. The screen flashes on and off like it’s a handshake issue every 5 seconds or so. Is there some sort of setting I’m missing or is set up incorrectly on the box, tv? Cannot find anything but knew years ago Samsung has handshake issues with Verizon. Have an newer HDMI directly from cable box to TV so no 3rd party hand off from audio. Thanks for the help.
