1080i vs 1080p

Is there a noticeable difference between these two? I understand that 1080p is full hd but 1080i must be very close.

from my understanding, 1080p was a more natural image.

1080i is interlaced, 1080p is not... ... Visually I would consider 1080i on a par with 720p.

Disagree. . on a native 1080 LCD it looks far better as it isn't scaled.

I guess they're two different kettles of fish, so I guess I can't call them equal. Progessive is much better for movies with heaps of motion and sports.

Agreed. If you have to choose betweem 780p or 1080i then go for 780p.

They both have a resolution of 1920 x 1080 pixels.

1080p is progressive. 50fps for Pal although most Blu-ray's are 24fps.

Digital display's can display a progressive signal, but not all can do 24fps and will repeat frames to get 50.

1080i is interlaced which means the frames are split into half frames or fields, with 1 field containing half a frame and the next containing the other half.

Most Digital display's cannot display a interlaced signal, so it must be deinterlaced first, giving 25 full frames.

720p is 1280 x 720 pixels and is progressive.

Some TV's can accept a 1080i signal but not a 1080p signal, but are just downscaling the 1080i signal to 720p.

I bought a newlcd tv last week and did considerable googling first.
The general consensus was to forget (i) or interlaced and go for (p) progressive. Under 40" for a tv you will not notice the difference between 720p and 1080p but the 32" Sony I bought had 1080p anyway plus freeview and it is magic.

I've seen websites make that claim also but in my own experience I would disagree.

TV3 on Freeview HD is the only channel broadcast as 1080i. TV1 & 2 are 720p and the rest are 576i.
