PVO YG-300 Pro projector with a resolution of 800 x 480 pixels and an image diagonal ranging from 25 - 150". This size depends on the distance at which the projector is placed in relation to the projection surface.

This particular technology takes its name from the initials of the words Liquid Crystal Display. The image is created by a liquid crystal panel that produces combinations of the three primary colors: red, green, blue. This results in very good color performance, even in black.

Brightness and contrast, or the 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 particular one has a brightness of 2000 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 appears faded and flat. In contrast, with a high contrast ratio, it appears more realistic and with greater "depth".

Brightness indicates how much light the projector can deliver to a specific surface size. The general rule suggests that "brighter" projectors should be preferred in rooms with plenty of light or multiple light sources, while "darker" ones should be preferred in dark rooms.
