It's not a very common aspect ratio these days, but if you're looking for a portable projection screen that's easy to transport (it's got a built-in carrying handle), set up, use, and take down, start with a 93 iNCH diagonal Draper Traveller 15:9 projection screen in either high contrast grey or matte white.

Pair it up with one of the NON-3D-ready 1280 x 768 DLP projectors that's featured in the slideshow to the left.

Of course, you'll also need to look into separately supplying/buying and connecting an audio system, one or more high definition A/V sources such as a Blu-ray Disc player/PS3, other gaming console, HDTV tuner or DVR, and the HDMI cables to connect it all. You may also want to consider purchasing a stand that will support the projector and a few components.
