For sure, image quality improvement is not just a matter of subjective perception, but indeed the effect of more information actually available. The level of detail gets to be five times higher than with standard definition: it goes from a frame of 576 x 768 = 442k pixels to one of 1080 x 1920 = 2.1M pixels. The aspect ratio is changed from 4\/3 to 16\/9, more natural for the visual angle of the human eye. The scene is wider horizontally (landscape format) and contains much more detail, giving greater depth to the image. Not to be underestimated, moreover, the presence of multi-channel audio, which greatly increases the sense of immersion of the viewer in the scene.

The resolution of HD also lends itself to multimedia screens, presenting at once images, videos and texts, as we usually see on a PC browser or tablet.<\/p>\n","protected":false},"excerpt":{"rendered":"
