How Does 4K Up-conversion Workīe it a display chip of a monitor or a television set, there are modules responsible for image scaling. Shortly speaking, an upscaled 4K will look better, but not astonishingly perfect. If the quality of the source is far too low (720p HDTV), it will never outpace the look of an ultra-high quality source (4K). Besides, it is worth noting that the upscaling quality very much depends on the sources. The truth is that sometimes you can't even tell the difference between an upscaled 4K and a native 4K video on the same 4K TV screen merely by the sight of your eyes. In theory, you would probably think if a video has a 4K resolution it will look perfect on a 4K TV, but this is not always the case. Upscaled 4K vs Native 4K, Is There Any Difference in QualityĪn upscaled 4K (from 1080p) video will, of course, look better than the one without upscaling (1080p) on a 4K TV, but a 1080p video can only approach its perfection on a 1080p TV. By contrast, 1080p refers to a content with 1920X1080 pixels and progressive scanning. To be precise, the distribution, 4096X21X2160, is for household media and cinema industry respectively. 4K resolution, also referred to 4K, means the horizontal display resolution of about 4096/3840 pixels and vertical resolution is around 2160 pixels.

Before we go further, let's make it clear the terms of 4K and 1080p resolution.
