The computer would then spray video out the port no matter what, even if it doesn't detect a device. You mentioned that you were using curved Samsung TV.  That is exactly what I'm running as well.  This probably won't help you, but maybe someone else that's reading this; for my shut down needs I set the computer to sleep the display after a certain amount of time which stops sending video.  Then I set the TV to automatically shut off after a certain amount of time with a loss of connection.  Now all I have to do it wiggle the mouse or press a key to wake the system up and press power on the TV when I want to start using it.
