The Da-lite Parallax 0.8 stood out as outstanding in this group in two particulars -- clarity of the image, and extremely wide viewing angle. Unlike most other ALR screens, the Parallax 0.8 shows absolutely no visible texture or shimmer. As far as image clarity is concerned, nothing beats it. It is tied with the DNP Supernova and surpasses all others.
Similarly, the viewing angle of 170 degrees is extremely wide. It is tied with the DNP Supernova and the EPV DarkStar9 on this attribute, but surpasses all others. The Parallax 0.8 is an excellent choice for any application in which you need to have the image highly visible across a wide viewing space.
At 0.8 gain, the Parallax is among the least bright of the eleven, but only when viewed from the center position. If you need a bright picture when viewed from the center you will need to use a brighter projector than you'd need with some of the higher gain competition. However, as you move away from the center viewing position, the Parallax will be brighter and more uniform than most of its competitors due to its extreme half gain angle. If you want the best of both worlds, a very bright picture at the center as well as from all angles, use the Parallax with a high lumen projector.
The most notable limitation of the Parallax 0.8 is that, in our side illumination test, it came in lower in contrast and color saturation compared to most of its competitors when viewed from the center. In any given ambient light situation with any given projector, black levels are not as deep and color saturation is not as rich as it would be on most other ALR screens in this review. This is another attribute that the Parallax 0.8 shares in common with the DNP Supernova. These two screens show almost identical properties in ambient light rejection, both from the side and from the top. They look extremely similar in black levels and saturation.
So the Parallax offers a trade-off -- it gives you the benefits of zero texture artifacts, a very clean picture, and an extremely wide viewing angle, in exchange for lower contrast and saturation at center axis. Having said that, it is important to keep in mind that in relatively low ambient light environments, you may be able to offset the contrast and saturation limitations on the Parallax by using a very high contrast projector, thereby ending up with the best overall solution for your particular needs. The Epson Home Cinema 1440 that we used as a source projector for these tests is bright but not as high in contrast as conventional home theater projectors. It works fine with ALR screens that have a better ability to amplify contrast in ambient light, but on the Parallax the picture looks comparatively flat. Choosing a higher contrast projector with this screen will help neutralize the problem as long as ambient light is minimized.
The Da-Lite Parallax comes in a fixed frame option only -- not motorized retractable or zero edge styles are available. The frame and screen are relatively easy to assemble, and the end product is light weight and easy to handle for mounting.
