Step-by-step explanation:
The five display resolutions on a Direct TV HD receiver are 480p, 720p, 1080i, 1080p, and 4K Ultra HD.
480p is considered standard definition and has a resolution of 854x480 pixels. 720p is high definition and has a resolution of 1280x720 pixels. 1080i and 1080p are both full HD resolutions with a resolution of 1920x1080 pixels, but 1080i interlaces the image while 1080p shows the full image progressively. 4K Ultra HD is the highest resolution with a resolution of 3840x2160 pixels.
