I have a VERY challenging family room in which I'm wanting to install a fully concealed Front Projection system. To achieve fully concealment (when the projector is not in use) would require me to mount my projector in a corner of the room behind some furniture at a 35+ degree angle at the screen.

The projector I want to use is the Panasonic AX200-U which includes up to a maximum of 25 degree offset, but no more. So I'm wondering f I'm using a matte low gain screen 1.1 to 1.3 and I we're to aim my projector at this kind of angle, is there any VP product that could help me "warp" this image to overcome the distortion I'm likely to introduce shooting at this kind of angle?

Thanks!

Since the keystoning is a type of video processing, I'm not sure what you are asking. If you are asking if it will do it better than the projector, the answer is "maybe" since most VPs I have used don't include this functionality. Since there are some relatively unobtrusive projectors out there, I'm not sure why you are wanting full concealment (or whether there are other ways to achieve this in your space). However, that is a question for the projector forums.

The procesors that use the Silicon Optix chip set such as the Algolith Dragonfly often have something called Image AnyPlace technology that allows for such correction. I have tried it and it works as advertised.

There is also a stand alone product.

projector oriented processors like Algolith dragonfly do this (Vantage HD probably does the same, as it is designed around the same chipset).

Note that this type of processiung will reduce the overall picture quality!

Yes, Vantage HD also has extreme keystone correction. You are able to adjust each of the four corners individually.
