A:Answer It depends on what your source material is. If you are only watching cable or OTA TV, or a standard Blu Ray disc, then the maximum resolution the TV will display is 1080P. You must be watching a 2160 source, such as a YouTube 4K video, a Netflix show filmed in 4K, or a 4K UHD disc in order for the TV to display full 2160 resolution. This is not a fault of the TV. It is completely normal.
