The native resolution is the number of pixels (pixels) a projector can horizontally and vertically project. Generally, the higher the native resolution, the more detailed the picture and the bigger working or gaming area it will provide.
In addition to the native resolution projectors can also display higher resolutions, which, however, is calculated by using the software. Which may impact on its quality and sharpness.
Contrast is a measure of the difference between the darkest and brightest part of an image that a projector can produce. A higher contrast ratio means that the projector is able to produce images with deeper blacks and brighter whites, resulting in more vivid and realistic images. Contrast is particularly important when displaying dark or shadowy scenes, where small differences in brightness can have a big impact on the overall appearance of the image
Indicates the shortest distance at which the projector is able to display high-quality, sharp image. The better models can project an image, even from a distance of just one meter with a...

Luminance is a key parameter for any projector and is usually measured in lumens. Higher lumens mean that the projector will be able to produce a brighter image, which is useful in brightly lit rooms or for large screens. On the other hand, a projector with a higher luminance may require more power and may produce more heat. Therefore, luminance must be balanced with other factors such as energy efficiency, size and weight of the projector.
Dobrý den, dá se na projektor připojit mobil přes USB? Popřípadě jak? Když USB zapojím automaticky se nenačte a přepnout jde pouze mezi HDMI, VGA a Video porty USB tam není. předem děkuji za odpověď
