Usually when you switch video inputs on a TV the input label is displayed for a few seconds until a picture is obtained from the source then it

will go away if not check your settings and see if you have the ability to hold the label and uncheck it the only ones I have seen this on is when

video is run through a receiver and someone hit the display button then it will retain the info you may also try hitting the display button on your

TV it should erase the input label until you switch it again.
