What is the difference between 1080p and 1080i?

Category: Electronics


First, let’s start with the “I” and “P”. The I stands for interlaced and the P stands for progressive. These two distinctions relate to the scanning technology of the television. The number 1080 (or 1920 x 1080) refers to the resolution.

Progressive scanning is the newer technology that is used on most televisions manufactured today. 1080P is ideal for watching live sports and other motion sensitive programs. It is technically better due to the progressive scan. HDMI cables are the preferred input option to feed the audio and video.

So which is better? In most cases it doesn’t even matter. Most cable companies only broadcast 720p signals anyway and most television with 1080i offer 720p. So it really comes down to when or if you have a digital input that can broadcast a full 1080p signal. Blu-ray discs and many video gaming systems offer a true 1080P signal. Until the cable companies get their bandwidth problems fixed, it is a meaningless argument unless you watch a lot of blu-ray movies.
