Is the a big difference between 1080i and 1080p??

Answer 1

How big the difference is depends on what you are using the set for.

As the previous answers illustrate, progressive scan gives you each frame all at once: 60, sometimes more, frames per second. Interlaced gives you the 1st, 3rd, 5th, etc lines, 30 times, alternating with the 2nd, 4th, 6th, etc lines 30 times (or more, again, depending on refresh rate)

If you're watching the evening news it won't matter. If you are into the things people get HDTV's to get into, though, you will notice differences if you compare the two.

For example I bought a 1080i set (can't afford a 1080p) and I use my Playstation 3 with it. Areas of high detail that are moving fast have a shimmer effect. Outlines of moving figures can appear sloppy or slightly jagged at times. Visual effects that are timed in sync or period with the refresh rate can produce noticeable optical illusions. This is true for video games and blu-ray discs as well. It is not as pronounced for low-def (such as dvd) but then you want the TV for the Hi-Def, right?

If you have a chance to, check out the difference between 480p and 480i. Any 720p set will do, if you know someone who has one. I have seen no better demonstration of the difference in quality between interlaced and progressive, than to start up a progressive-capable ps2 game on my hdtv, play a little bit, then go to the options and activate 480p. The first time I saw the difference, it was stunning.
480p is more sharp, crisp, clear, and beautiful BY FAR than 480i.

granted, 1080i looks great, and it looks better than the 720p that my PC uses on the same tv. But in a side-by-side comparison, 1080p will look much better if it's showing content that does it justice (rather than, say, a videotape)

So yes, there is a big difference. Unfortunately there's a big difference in price, too. :(

Answer 2

there's a extensive distinction. 1080p in simple terms seems superb! I used to play on a television that basically supported 1080i yet as quickly as we've been given our new 1080p television is seems so plenty extra powerful. additionally, if your television helps 1080i and 720p flow with 720p while playing your PS3, it seems plenty smoother

Answer 3

If you know what you're looking for there is a noticable difference, but to the average consumer, the honest answer is no.

First, remember that video is a series of still images, each still image is called a "frame." There are 30 frames of video per second (24 frames per second in film).

The "i" stands for "interlaced." This means the picture being displayed is only updated every other frame. The TV scans a series of horizontal lines, but only the odd numbered lines. Once it finishes displaying the odd numbered lines, it displays the even numbered lines. So at any given time, you are seeing half of two frames.

Progressive scan updates the entire image each frame.

Right now the only 1080p content available is on the High Definition DVD formats (HD-DVD and Blu-Ray). The highest resolution available through any form of broadcast is 1080i.
