Interchangeable lenses and lens shift function (called lens shift), for ideal image quality under different conditions of housing (including a large range of distances from the projector screen). H5080 has a brightness of 1,600 ANSI lumens and a 25,000:1 contrast, and H5085 1800 ANSI lumens respectively and 35.000:1. Both models offer ISF calibration, with 3 HDMI inputs and the fan noise level only 27 dB in ECO mode.
Both projectors are perfect products for demanding users. They offer not only excellent picture quality, but also a variety of solutions to facilitate its installation and operation. The lens shift function (called Lens Shift) work in two dimensions (vertical and horizontal), which allows for proper image geometry.
Vivitek H508x projectors are equipped with two 12V trigger, enabling the development of automatic control of screen and / or obscuring of the room (leaving the blinds) at the time the projector is turned. When turning off the projector screen is retractable and the blinds raised. This solution is extremely convenient when a projection room is also used for various other purposes.
When installing the projector is often inconvenient to obtain an appropriate image size of the place where you want to install it - in the case of projectors H508x is much easier because the user has a choice of three lenses: krótkoogniskowy (VL903G), standard (VL901G) and long-distance (VL905G .) The first allows for the maximum size of an image from a short distance (less than 2 m), the second allows the image to get the maximum distance of 3-4 m, and the third with a distance of 5-7.5 m, which is the end of the hall or from the projection booth at the cinema .
Calibration ISF (Imaging Science Foundation) is a precise setting of the various image parameters (eg saturation of each color component, the level of white and black) so that the image on the screen corresponds to the original. Calibration is performed at the installation site in the target projector projection conditions, for each of the separate input sources (DVD, BluRay, computer, etc.). The process is carried out by a professional ISF certified and suitable measuring equipment.
