Hopefully someone can help me. I thought it would be pretty straight forward connecting my mbp to my lcd samsung. I'm using a belkin hdmi to dvi, and after I connect and select the input on the tv, all I see is the original os x background on the tv. so at least im seeing something and the cable seems to be working, but that's all I see. I can't get anything else to display. When I watch instruction videos people just seem to get the whole desktop with dash and everything to display right after connecting. any advice would be extremely appreciated, thanks.
