ViviPeaking
Most likely this feature is the same as the Optoma's Pure Color. Vivitek describes it as a dynamic sharpening control, and it seems like a typical Brilliant Color type implementation. It's mostly like dialing up the "pop and wow" of the image. This feature can be really nice, but, like most dynamic features, takes a toll someplace else. You want the more dynamic look, you'll also get a less natural look. That's a common trade-off. View the three images immediately below. The first one has ViviPeaking set to 0, the second, set to 1, and the third, set to the max which is 3. Three's pretty nasty.
Note these two images are "placeholders" the correct three images are coming.
Image with Pure Color Off.
Image with Pure Color set to 2.
That of course just gives you an idea of the extra kick from cranking up their peaking feature. One can be a touch over the top, depending on the content. Hey, if you like it...

Interchangeable Lens System
Choose between two zoom lenses - the standard lens, which most will use for ceiling mounting, a longer zoom which will primarily be used by those rear shelf mounting, or a fixed wide angle lens suitable for rear screen setups, or very close, front ceiling mounting. The lenses use a bayonet mount and easily snap in. You can get the projector with any of the three lenses.
