Results, impressions


By: Sander Sassen

Of course our measurements of lumen output do not tell you anything about the image quality of a projector, they only give an impression of the performance of the opticals. Image quality is obviously subjective to a certain extent, not everybody likes a sharp image, some favor a slightly less sharp image for a more film like experience. Fortunately sharpness can be easily controlled by the focus ring on the projector's lens. Important factors to consider when evaluating image quality is whether the image is free of artifacting, especially where dark and light overlap, or blend into one another. And horizontal and vertical panning of complex scenes can also clearly show any issues with image quality. Unfortunately these are hard to capture in a still image, and are best described in words.

From the outside the ScreenPlay 7210 does not differ that much from the 5700, the exterior, available connections but also the noise production, controls and menus are all the same, but for a few minor differences such as both vertical and horizontal keystone on the 7210. The image quality of the 7210 is a notch above that of the 5700 though, with a natural fluidity to the image that is immediately apparent when comparing them side-by-side. Much like the perceived smoothness of a 100Hz TV-set versus a 50Hz one, the 7210 has a similar appeal. The progressive scan processing on the 7210 is also clearly improved on the 7210, it lacks some of the pixelating seen on color fringes, or dark scenes with the 5700. But these are only visible for the trained eye anyway, usually at arm's length from the screen, and are mostly due to our prolonged experience with the 5700, thus being familiar with its (minor) shortcomings.

Sharpness was best when feeding both the 5700 and 7210 from the Denon DVD2900 with progressive scan output, apparently the Silicon Image PureProgressive (SiL504) processor used in this DVD player does a better job than the Faroudja DCDi FLI2310 found in both the 5700 and 7210. The Faroudja has a tendency to smooth the image out a little more, whereas the SiL504 retains the original sharpness of the image. Unfortunately there is no sharpness setting in the menu of either projector, so we cannot make any adjustments. Obviously the image could be blown up to a larger format due to the ScreenPlay 7210's higher resolution, but it was easier to tell the projectors apart by the aforementioned fluidity of the 7210 rather than their resolution.
