The number of televisions that can actually accept 1080p is very limited. There are only a few out there. But buying something with native 1920x1080 resolution is NOT a guarantee that it can actually accept 1080p: many can still only take 1080i since 1080p is not an actual official HDTV format yet (the ones that do take it basically deal with it like a PC resolution).

The "wobulation" thing is a DLP specific cheat to use a 960x1080 chip to discretely reproduce full 1920x1080 images. Just like they also use a color wheel so that a single chip can reproduce all thee colors. Both of these compromises were made to keep costs down, since even one lower resolution chip is quite expensive. However I thought there were some wobulated DLP sets that did accept 1080p input.

To avoid that sort of thing you'd have to look to direct-view LCD or plasma, or LCOS/DILA/SXRD rear projection.
