HDTV works well for slides if you like a great loss in contrast and your colors muted. The use of HDTV for slides shows that one likes to spend money and does not understand a damned thing about slides. So if you are ok with that, swallow your pride, go ahead and use HDTV, please.
I am not just sayin'. I am saying loud and clear. If you are offended, then we know what you opinion is worth so keep it to yourself.
