4K TVs are capable of producing stunning images, however, this is dependent on the quality of the source content.
For example, the majority of Free-To-Air channels are broadcast in Standard Definition (576i) or High Definition (1080i), compared to the 3840p resolution in a 4K TV.
When viewing these channels, while still producing excellent picture quality, a 4K TV must stretch or "scale" the image to fill its native 4K resolution.

When viewing these channels, while still producing excellent picture quality, a 4K TV must stretch or "scale" the image to fill its native 4K resolution.
Doing this means that what was one pixel on the standard or high definition TV, will be stretched over several pixels on the 4K TV.
Scaling allows the source content to fill the screen and produce an excellent picture, but it can't significantly improve the quality present in the source material, as the data or information simply is not there to tell the TV what to display.
