Digital keystone correction reduces resolution and induces moire' in the image. If you feed a multi-burst, or one-pixel-on-one-pixel-off pattern to your projector, you will usually see that only one click in either direction of keystone adjustment will visibly affect the image quality. NEVER use it for anything but static images, such as Power Point presentations and the like. If you value image fidelity and picture quality for motion programs, avoid it like the plague. Digital keystone correction is for convenience, not quality viewing of moving pictures. Attention to detail in following the manufacturer's mounting instructions is the best path to optimum image quality and realizing the most value from your projector.
