Aspect Ratio and Resolution

Unsure of the User Interface on your TV? Click here

 

  • Aspect Ratio is the proportion between the width and height of a TV screen
     
  • Resolution defines the amount of pixels displayed on the screen
     
    • 4K (Available on some TiVos)
       
    • 1080p  (Available on TiVo)
       
    • 1080i
       
    • 720p
       
    • 480i (Standard Definition)
       
    • i or p refers to the scanning technology
       
      • i = Interlaced scanning technology. It scans and refreshes even and odd lines separately, but produces very sharp pictures in general when the image is still or has little motion
         
      • p = Progressive scanning technology (newer). Scans and refreshes all lines at the same time. Progressive scanning produces smoother motion with less blurring. It's perfect for high action movies and sports.
