This thread shouldn't turn into an SD vs. HD TV argument, but HDTV can absolutely be beneficial on smaller screen. It's more about distance from the screen than the size of the screen. If it's a TV that you're going to be watching up close to, such as in a bedroom or office, then even if it's only 22" you will still benefit from HD. If it's a 32" screen that you're watching from 10-12 feet away in a living room, then SD, or 720p HD (not full HD), could be considered sufficient.
