1080p displays the resolution with 60 lines all on the screen at the same time which means no image blurr it is currnetly the super hd of the day even though most things are not made and none are brodcast in 1080p resolution.
1080i has 30 lines going vertically on the screen and then after 1/30 of a second the 30 horizantal lines fill in but in high action sports or movies this creates blurr thats why movies are made in 1080p.
So basically 1080p is better that 1080i in every way, actually 720p is better than 1080i lol…

Assuming a 60 Hz refresh rate, 1080p displays a full 1920×1080 frame 60 times a second. 1080i displays half of a 1920×1080 frame (called a field) 60 times a second, with fields displaying in a ABABABABAB pattern, and 540 of the A fields are refreshed, and the next refresh, the other 540 B fields are displayed.
Now, here’s the thing - there’s not much in the way of 1080/60p content yet (that’s 1080p content at 60 Hz) that’s not from a gaming system or PC or something similar. There just isn’t enough bandwidth in our current television delivery methods to deliver 1080/60p content yet, so we’re stuck with 720/60p (720p at 60 Hz) and 1080/60i (1080i at 60 Hz) However, most TV shows and movies are filmed at 24 frames per second. What this means is that for TV broadcast at 1080i, it can be “deinterlaced” from a 1080/60i to a 1080/24p signal, by reversing the process that took the original 24 fps source material and made it a 60 field interlaced signal. (Not all TVs support this - some do it automatically, some have to do it manually through a Film Mode or similarly named function - why all TVs don’t support this can be explained simply: consumer electronics manufacturers are assholes) Thusly, we don’t really actually have much of a need for 1080/60p broadcasting quite yet.
The basic point is that 1080i and 1080p will give you a 1920×1080 image, 1080p will look smoother than 1080i given identical refresh rates, but 1080i can be used as a delivery method for film-based material, which is most TV and movies. It’s confusing, but the way interlacing works is kinda confusing, but just realize that while progressive resolutions are better than interlaced ones, you’ll still get about the same resolution using either 1080 format, although 1080p will look better, but outside of gaming, 1080/60p doesn’t really exist.
