Description
Professional projector DW770UST by the company Vivitek, with resolution 1280 x 800 pixels. The throw ratio, or projection distance ratio, indicates the width of the image produced by the projector when placed at a specific distance from the screen. For example, a throw ratio of 1.3:1 means that the image will be 1 meter wide when the projector is placed 1.3 meters away from the screen. This is an ultra short throw projector as it has a Throw Ratio of 0.35:1, less than 0.40:1 that characterizes this category. Practically, this means you can place it below or above the projection surface, eliminating any obstacles, making it useful in small spaces or presentations.
The projection technology is the way the projector's lamp light is converted into an image to be projected through the lens onto a surface. This one is DLP (DMD) technology and its lamp is regular, which has higher brightness and shorter lifespan compared to LED lamps.
This technology is named after the initials of the words Digital Light Processing, it is the most widespread projection technology, and there are projectors with one or three DLP chips. The image is created when the projector lamp light passes through a rotating color wheel and is reflected by a chip with hundreds of thousands of tiny mirrors, each corresponding to a pixel. This chip is called DMD (Digital Micromirror Device). They are suitable for spaces with plenty of lighting, such as classrooms or conference rooms, and have good color performance.
Brightness and contrast, or contrast ratio, are two very important features that are taken into account, in combination with the projection distance and the maximum diagonal you want to achieve, for the selection of a projector. This one has a brightness of 3500 ANSI Lumens and a contrast of 10000:1.
Contrast indicates the difference between the darkest and the brightest part of an image and is an indicator of image quality. The image projected by a projector with a low contrast ratio looks faded and flat. In contrast, with a high contrast ratio, it looks more realistic and with greater "depth".
Brightness indicates how much light the projector can deliver on a specific surface size. The general rule suggests that "brighter" projectors are preferred in rooms with plenty of light or several light sources, while "darker" ones are preferred in dark rooms.
It is equipped with an Ethernet port, so you can connect wired to your local network and watch a program online or download software updates.
