Yep, just to confirm, this has been tried before, it's not possible to do unfortunately. One way round this, could be with Nokia Beamer when it gets released. So if you did want your phones screen on a large TV, you should be able to plug a laptop into the TV through HDMI, then have your phone 'beam' it's screen to the laptop, which would in turn show up on the TV screen. I've obviously not tested this yet as Nokia Beamer is only available on Nokia Black, but it should work.
