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.
