Professional projector LS711W by the company Viewsonic, 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.
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 LCD technology and its lamp is laser type, which has a longer lifespan compared to LED lamps, as well as very high brightness and excellent color and black performance.
This technology is named after the initials of the words Liquid Crystal Display. The image is created by a liquid crystal panel that produces combinations of the three primary RGB colors: red, green, blue. This results in very good color performance, even in black.
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 4200 ANSI Lumens and a contrast of 3000000:1.
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.
