HDMI Desk Dock

[Shadez]

Ok so I accidentally set my clock program as the default app to launch when I put the phone in the HDMI cradle, and for the life of me can't figure out how to get the mirroring option back. I went to the clock app and the clear default isn't highlighted. So whenever I put it in the cradle it goes right to the clock, anyone know how to get the mirroring image selection back?

Thanks!
