The LG 4k television is capable of upscaling 720p and 1080p content on a nanocell 65-inch screen at a 5-6 meter viewing distance. Upscaling is an automatic process that the TV uses to display the content on the screen, as the 4k TV has a higher resolution than the 720p and 1080p content. The TV first scales the image to match the native resolution of the panel, and then it uses various algorithms to enhance the picture quality. The upscaling performance of the LG 4k television is generally good, as it is able to produce a clear and sharp picture with minimal loss of detail. However, the quality of the upscaled content may not be as good as native 4k content, as the TV has to use its own algorithms to create the additional pixels needed to fill the screen. Overall, the LG 4k television is a solid choice for those looking to upgrade their viewing experience with 4k content, and it is able to handle 720p and 1080p content well.
