We are using two monitors at the front of our church mounted in portrait mode. I am using a flash drive with event flyers and a welcome screen sort of like marquees as people enter. I had to trick the monitor by using multiple images in a loop to keep the Samsung logo from coming onto the screen. I was told there is no way to keep this from happening because "There is no option in the Samsung Tv to disable the Samsung logo from the TV directly as it is manufacture setting and can not be removed with the service menu as well". What I am doing works but I wonder if anyone else had any experience with a better solution.
