Epson Eh-Tw5400 Projector Τεχνολογίας Προβολής 3Lcd Με Φυσική Ανάλυση 1920 X 1080 Και Φωτεινότητα 2500 Ansi Lumens Λευκός

Epson projector EH-TW5400 with Full HD (1080p) resolution and image diagonal ranging from 34 - 332 ". This size depends on the distance that the projector is placed in relation to the projection surface. In this case the projection distance is in the range 1.62 - 1.95m The throw ratio or projection distance ratio indicates the width of the image produced by the projector when placed at a certain distance from the screen, for example throw ratio 1.3: 1 means that the image will be 1 meter wide when the projector is placed at a distance of 1.3 meters from the screen. Projection technology is the way in which the light of a projector lamp is converted into an image to be projected through the lens onto a surface. This is 3LCD technology and its lamp is simple, which has higher brightness and shorter lifespan than LED lamps. This technology takes its name from the initials of the words Liquid Crystal Display, has been developed by Epson and is an evolution of LCD technology. The image is created by 3 panels of liquid crystals each of which produces one of the basic colors: red, green, blue. The 3 colors are combined through prisms and projected simultaneously by the lens as a complete image. This results in much better color performance than black LCD projectors. Brightness and contrast, or the ratio of contrast, are two very important characteristics that are taken into account, in combination with the projection distance and the maximum diagonal that you want to achieve, when choosing a projector. This one has a brightness of 2500 ANSI Lumens and a contrast of 30000: 1. Contrast indicates the difference between the darkest and 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. On the contrary, with a high contrast ratio it seems more realistic and with greater "depth". Brightness indicates how much light a projector can deliver on a given surface size. The general rule suggests that the "brightest" projectors are preferred in areas with enough light or several light sources, while the "dark" ones are preferred in dark areas. Noise Level: 37dB Lamp Power: 200W Lamp Lifespan (Maximum): 7500hrs Connectivity: Analog Audio, HDMI, MHL, USB, VGA The users who have bought it stand out mainly because it has a fairly bright image and has a clear image.
