I have a distinct feeling you are in CLONE mode and not EXTENDED DESKTOP since you did see shortcuts, etc on the tv..
I don't see where administrator access would have any bearing on that.

Have the tv hooked up and turned on

Right click anywhere on a blank spot on your desktop

Click on PROPERTIES

Click on SETTINGS

Click on Monitor #2 to highlight it

Check the box that reads EXTEND MY WINDOWS DESKTOP ONTO THIS MONITOR

Click APPLY, then OK.

You should now be in EXTENDED DESKTOP mode and be able to click and drag
the singer's window over to the TV, size it and double click to lock in place.

Hope this gets it.
