Additional information
Due to the nature of liquid crystal display (LCD) technology, the picture resolution is always fixed. For the best
display performance, please set the display resolution to 1920x1080 pixels with an aspect ratio of 16:9. This is
called “Native Resolution” or maximal resolution – that is, the clearest picture. Lower resolutions are displayed on a
full screen through an interpolation circuit. Image blurring across pixel boundaries can occur with the interpolated
resolution depending upon the image type and its initial resolution.
