Image quality is acceptable for most uses.
At lower resolutions, you can either scale to full-screen or show a partial screen. With higher resolutions, the only choice is to compress the image to full-screen. However, interpolated images are more readable than they are on many other projectors, though there are still some artifacts. Ease of use is a mixed bag, with well-designed menus and easy cable setup complicated by the need to install a driver to control your mouse from the remote. All told, however, this is an attractive projector for portable presentations, at an attractive price.
