I have a TV tuner on my laptop(HP Pavillion dv8t) and I want to watch it on a bigger screen ... can I use the imac as an external display using a mini display port to dvi then dvi to hdmi??

I didnt know they made those... I knew they made mini display to hdmi adapters but not cables... could you give me a link
