Oh what have I done?????

Did you go back into your "Display Options" in the Control Panel and make sure the 2nd TV is set up for "extended"? Sometimes computers seem to have a mind of their own & settings can revert back to defaut. If the settings are not correct, then yes you will see the same thing on both monitors (computer & TV for singers). When you're doing a Show and in a rush, it is sometimes hard to remember everything - I've done it too, only to find out it was a simple fix.

Hope this helps.
