An article of mine discussing the output of an X50v on to a TV was recently published. You can read more about it here.
As for getting your h2215 on a TV, you will need a VGA-out accessory such as the Margi Presenter-to-Go.
Really though, for a true VGA-out solution, you can't go past the Dell Axim X50v. With third-party software, you can even push the output past 640 x 480 to 1280 x 1024. I plan on writing an article on that when I have the time.
