Epson Business projector EB-2250U with resolution of 1920 x 1200 pixels and a diagonal image size ranging from 40 - 260". This size depends on the distance at which the projector is placed in relation to the projection surface. In this case, the projection distance is within the range of 1.5 - 9m. The throw 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 have a width of 1 meter when the projector is positioned at a distance of 1.3 meters from the screen.

The projection technology is the way in which the light from the projector's lamp is converted into an image to be projected onto a surface through the lens. This particular projector uses 3LCD technology and its lamp is regular type, which has higher brightness and shorter lifespan than LED lamps.
This specific technology takes its name from the initials of the words Liquid Crystal Display, it has been developed by the company Epson and it is an evolution of LCD technology. The image is created by three liquid crystal panels, each of which produces one of the primary colors: red, green, blue. The three colors are combined through prisms and projected simultaneously by the lens as a complete image. This results in a much better color performance, even in black, compared to LCD projectors.

The brightness and contrast, or contrast ratio, are two very important characteristics that are taken into account, along with the projection distance and maximum diagonal you want to achieve, for selecting a projector. This specific one has a brightness of 5000 ANSI Lumens and a contrast ratio of 15000:1.
The contrast indicates the difference between the darkest and brightest parts of an image and is an indicator of image quality. The image projected by a projector with a low contrast ratio appears washed out and flat. On the contrary, with a high contrast ratio, it appears more realistic and with greater "depth".
The brightness indicates how much light the projector can deliver on a specific surface size. The general rule suggests that the "brightest" projectors should be preferred in spaces with sufficient light or multiple light sources, while the "darker" ones should be preferred in dark spaces.
