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.
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
Resolution is one of the most important parameters of any projector. It determines the number of pixels that the projector can display and thus affects the detail and sharpness of the image. Common types of resolutions include Full HD (1920×1080 pixels), 4K (3840x2160 pixels), and XGA (1024×768 pixels). Higher resolutions generally provide a more detailed and sharper image, but may also require more computing power and can be more expensive.

The projection distance type refers to how far the projector must be from the screen to produce an image of a certain size. A projector with an ultra-short throw distance may produce a large image when very close to the screen, while a projector with a normal throw distance may require a greater distance. The type of projection distance you need will depend on the specific needs of your space and the type of image you want to create.
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...
dobry den, rozhodujem sa medzi dvoma projektormi: Optoma HD27 a Optoma HD142X. Chcem sa opytat, v com spociva zasadny rozdiel medzi tymito projektormi? dakujem
dobry den, rozhodujem sa medzi dvoma projektormi: Optoma HD27 a Optoma HD142X. Chcem sa opytat, v com spociva zasadny rozdiel medzi tymito projektormi? dakujem
Musím si postěžovat na špatnou kvalitu zpracování projektorů Optoma, měli jsme bohužel 3 zkušenosti. První hd141x dost bzučel a přehříval se, až z toho po roce praskla lampa. Druhý hd27 radši po pár zapnutích se nechtěl ani zapnout. A teď třetí znova hrozně bzučí, ten předchozí alespoň nebzučel. Obrazově je Optoma hd27 v téhle cenové relaci asi bez konkurence bohužel.
