What's the better resolution, 720p or 1080i?

Question

Do all HDTVs come with both?
Which is going to be the standard?

Answer 1

To explain it in simple terms, here's is it

Pixel Count (The amount of details the Tv can produce)
720p = 1280 x 720 x 50** = 46 million pixels of details
1080i = 1920 x 1080 x 25* = 52 million pixels of details
1080p = 1920 x 1080 x 50** = 104 million pixels of details


*1/25 second is the time taken for interlaced piture to scan its top+bottom fields
**1/50 second is the time taken for progressive scan picture to scan both fields

Conculsion - at a time, 52million pixels and 46million pixels of details are displayed on a 1080i and 720p respectively. Although 720p loses out 6million pixels of details, but because of its Progressive Scan, movements/motion on 720p are displayed more naturally. And most importantly, 1080i will only seens to produce more details to the naked eye comparing to 720p when it's displaying on a screen of 50" and above. Thus, u can say that 1080i will only be better than 720p if a still image is being displayed. =) Of course 1080p is the very best among all.

Answer 2

was just looking at that myself yesterday. It appears there are two HDTV standards,, 1366X768 and 1920X1080. The 1080 machine will display a true full 1080i and possibly 1080p, in the future, check the specs of the tv your looking at. The 768 will use a scaler to display it's approximation of a 1080i signal, but it's pixels will allways limmit it's dispaly resoloution to 768 vertical lines maximum. Go with the 1080 if you can afford it, it has twice the pixel count of the 768, about 2 million vs about 1 million. But I have to say, I have a 1366X768 and the picture, when i feed it with a 1080i sig is really crystal clear, but the 1080 should, theoreticly, be twice as good.

Answer 3

i believe the answers on here are very confusing and I have been confused for the last two years which is why I haven't bought yet.

I believe 720 P is what the major networks broadcast in for some events like the world series and the superbowl. so 720 P will work just fine. the other resolutions bay be better but they can nly go so far.

1080P gives the best picture of a rear projection set because it fills in the gaps. it makes a lower resolution digital signal look better because of it's programming.

here's what I suggest. will you watch any action sports on the TV? if no, then it doesn't really matter. if yes, head down to the TV store on Sunday and watch football on the TV's. take your time and see which sets hold the picture well when the player is running. if the runner is surrounde by pixels then the picture is pixelating and move on to the next set. find a good one and buy it or save up until you can afford it.

don't throw good money after bad. don't spend $2000 now and wish you had saved up and bought a much better TV for an additional $800.

Answer 4

The standard will be 1080p -which is the highest standard currently available for full HDTV. But to answer you first question, 1080i is better than 720p.

Answer 5

these people are all wrong. Its 720p. The 1080i is a higher resolution, but isnt a true resolution. because its interlaced,it shows half the lines every other frame. It is essentially 540p. 720p (for progressive) shows all 720 lines every frame, and looks better.

Answer 6

with regards to resolution, the higher the number the better!
so, answering your question is simply 1080i is better than 720p.

it really depends on the manufacturer on what do they want to sell just like other devices which varies accdg to brandnames.

Answer 7

1080i is better 720p is for cheap *** hd tvs
