The laptop display resolution has nothing to do with the TV. Now what the video card can output on the laptop is another story.
Torrent = the index and transfer method of the file.
The movie itself would be a normal video format: mkv, mp4, avi, etc.
You can get a set-top box like a popcorn hour, wd tv or even better a box that supports XBMC, plug an external into that with the files on it, and then play it on your tv and then your laptop will have nothing to do with playing the media just downloading it.
