TVs with 4K upscaling

4K upscaling

— a feature that allows 4K and 8K TVs (see "Display resolution") to increase the resolution of the original "picture" to 4K, if it is initially lower. Thus, for example, you can view a movie in 4K, originally recorded in Full HD (1920x1080). At the same time, note that this is not just about “stretching” the image to fill the screen (all TVs are capable of doing this), but about special processing, due to which the actual video resolution is increased. Of course, such video will still be inferior to content originally recorded in 4K; however, upscaling provides a noticeable improvement in quality over the unprocessed signal.
