Misconceptions on Video Technical Details

Now where should I start? Hmm.... Let me think... Okay then. Today I shall talk about the misconception on Full HD.

Many consumers are always confused with the difference between 720p and 1080i. Now what's the main difference? What does the P and the I stand for? Well, the p stands for progressive scan and the i stands for interlaced scan. Interlaced scanning uses alternate lines to form an image on the screen in this context, 1920X1080i resolution. Progressive, on the other hand uses both the alternate lines and covers them up totally with the progressive scan.

Basically, 720p is of a lower resolution compared to 1080i. 720p supports 1366X768 pixels, but due to the progressive scan it would be clearer compared to 1080i. But although 720p is clearer, 1080i has a higher resolution and of a higher framerate. Other than that, there are no other differences compared with 720p. Of course, 1080p is the best since it combines both the pros of 720p and 1080i. But at the end of the day, it still depends on your own preference. Personally, I feel 720p is better. Well, that's just my humble opinion. :D

The next part will be on the different cable connectors. :D
