I have a Samsung TV I am using as an external monitor on my laptop.  This advertisement just stated to display on the screen and I can find no way to turn it off.

I am sure this is frustrating for you. It appears the the Demo Mode on the unit has been turned on. Press the Vol Up on the monitor. When the Volume OSD shows, press and hold Menu for 5 seconds to switch to Home Mode.
