Panasonic PT-DZ770UL WUXGA DLP Projector Review
PT-DZ770UL Optional Lenses
For more flexibility of installation, Panasonic offers a total of seven lenses to choose from, depending on your installation needs. The standard lens (which comes with the PT-DZ770U projector and was used for this review) has a throw ratio that ranges from 1.7 to 2.4 (this means the projector can be placed at a distance from the screen that equals 1.7 to 2.4 times the screen width). There are three long throw, zoom lens that have throw ratios 2.3 to 3.6:1, 3.6 to 5.4:1 and 5.4 to 8.6:1. There are also two shorter throw lenses whose throw ratios are 0.8 to 1.0:1 and 1.3 to 1.8:1. What does this all mean? It means that by choosing the appropriate lens, the projector can display a fairly large 200” diagonal image at distances ranging from as little as 11.3’ or a far as 122.7’, though the recommended maximum distance for the standard lens is 33.8’ for that size image.
There is also a wide lens (fixed at 0.8 throw ratio) available for rear projection applications. Street prices on these lenses are around $1800 for the standard lens, $2100 for the fixed lens and $2900 for the short throw zoom lens.
DICOM Picture Mode
Panasonic has included a special picture mode to the PT-DZ770UL that displays images simulating the DICOM (Digital Imaging and Communication in Medicine) standard used with B/W medical imaging (such as X-rays). This mode optimizes black/gray/white detail. Like other projectors that include such a mode, it is not intended for actual medical evaluation, but it allows for more accurate training of medical students, as well as more detailed medical imaging presentations.
Side-by-side Image Display
The PT-DZ770UL has a mode that allows the projector to display images from two different sources side-by-side on the screen. This allows for easy before/after comparisons or could include a static image alongside a video.
Multi-screen Support with Edge blending
Multiple PT-DZ770UL projectors can be used to cover a wider image over multiple adjacent screens. The projector includes multi-screen processing, edge blending and color processing to ensure a seamless transition from one screen to the next.
PT-DZ770UL Horizontal and Vertical Lens Shift
To facilitate ease of installation, the Panasonic PT-DZ770UL has manual lens shift in both the horizontal and vertical directions. There is a maximum of +50% vertical lens shift (upward if table mounted) and +/- 10% horizontal shift (left and right).
