When your selecting a new TV, many wonder “Is there really a difference between 720p and 1080p?”.
What does 720p and 1080p really even mean?
720p:
The 720 represents 720 lines of vertical resolution (720 horizontal scan lines), and the letter p stands for progressive scan (not “720i” or interlaced)
1080p: (aka. full HD or full High Definition)
The 1080 represents 1080 lines of vertical resolution (720 horizontal scan lines), and the letter p stands for progressive scan (not “1080i” or interlaced)
So what makes a 1080p better than a 1080i?
Progressive (1080p) vs Interlaced (1080i): Progressive scan processes the images twice as fast as Interlaced. This faster scan rate makes for a picture that is more crisp, clear, and vivid.
