Answer:
Not all 4K TVs have an upscaling feature, but many do.
Upscaling is a process of converting lower-resolution content to a higher resolution in order to improve image quality.
1080p content, for example, can be upscaled to 4K.
Most upscaling is done by the TV’s processor, which uses algorithms to fill in the missing information.
The results aren’t always perfect, but upscaling can help improve image quality significantly.
If you’re not sure whether your TV has an upscaling feature, check the manual or online documentation. Many manufacturers make it easy to find this information.
