We determined that the 7,500 Kelvin color-temperature setting actually came closest to the NTSC standard of 6,500K (who knew?), and having the gamma set to Cinema 1 gave us the greatest range from black to white (contrast ratio). Grayscale prior to calibration was reasonably close to the standard, but afterward, we were able to improve it to near perfection.
Color decoding was not perfect, pushing red a little and somewhat minus green, but not as bad as many displays we've tested. The lens does exhibit some chromatic aberrations (red and blue fringing along white lines), but considering the expense of good lenses and the low cost of the Z2000, this is entirely understandable.
After setting up and calibrating the projector, we watched some of our reference DVDs and some HD material from Time Warner Cable. Our benchmark Seabiscuit looked pretty good, with solid detail and color saturation. Star Wars: The Empire Strikes Back looked impressive as well, but scenes taking place in space did appear a bit noisy.
HDTV sources looked mostly excellent, although again there was some noticeable noise in dark scenes. With channels such as Discovery HD, which produces most of its shows in HD video, the picture looked awesome. Conversely with HDNet Movies, which airs a lot of film-based HDTV content, the material didn't look as clean. Film-based HDTV was simply a lot noisier looking.
Resolution is excellent; the projector measured a full 720 lines on a 720p resolution chart using the component-video inputs. As we mentioned previously, the projector is unable to display 1080i via its DVI input.
