- 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.
