All of which makes the PH30N's native resolution equivalent to 720p, rather than actually being 720p.

And the key point is that the ability to resolve detail is similar enough to what it would be with a true 720p native resolution that any difference would be hard to see. That said, whatever detail is lost in the translation may well be made up for by the slight increase in pixel count. The interpolation, in turn, can introduce artifacts, primarily in repeating patterns, as demonstrated by one of my test images that's designed to show these artifacts. But the difference in pixel count means there isn't a one-to-one match between the number of pixels in the original image and the number on screen, which requires interpolation from the original image. This works out to essentially the same image resolution-defined as the ability to resolve detail-as a 720p chip, which offers just under 1 million pixels. According to LG, the chip puts two 960x540 images on screen for each video frame, or just over 1 million pixels. The projector is built around an LED light source rated at 30,000 hours and a 0.23-inch 960x540 DLP chip that uses TI's XPR fast-switch pixel-shifting. But it actually doesn't deliver a native 1280x720 resolution.
