I have a 2011 13" MBP on 10.7.2 and whenever I plug in my Macbook Pro to my tv from mini display port to HDMI something weird happens. When I plug it in the tv screen changes to the default background that comes with Lion even though I have a different background image but nothing else shows up. No dock no widgets nothing. Does anyone know how to fix this or if there is a problem with the connection?
