720p better than 1080i? Is this true?

Makes perfect sense to me, your not thinking of 1080p are you? Because 1080p is not the same as 1080i.

Progressive is like the full image compared to interlaced which is every other line...
hence the 'I' vs ''P'

There is much more information in 720p compared to 1080i.

Progressive > Interlaced.

But yes. Let's be clear that we are NOT talking about 1080p here.

Like the article says, you're getting 720 all the time against what is essentially 540 all the time.

1080i is a bit better then 480p, so 720p is much better then 1080i, 1080i = 560p.

The article is a bit misleading.

While scenes with high amounts of motion will look better in 720p, scenes with many still frames look better in 1080i.
1080i gives a sharper image than 720p. That is why most HD TV is broadcast mostly in 1080i.
Channels like ESPN are broadcast in 720p to better handle the motion.

both are the full image lol!not it being the full image is an urband legend!

progressive is they do like a printer scan one line after another ,interlaced is the do odd line then even line!the second is more forgiving because the timing is a bit different!we talk 1 / 30 of a second here!

1080i take a bit more ressource then 720p.but 1080i give you 1080p quality!everage user wont mind!for most 1080i is a very good compromise!1080i is more work to adjust !why ?because people are more busy convincing you to use 1080p then actually respond on how to maximise setting so you get the best 1080i experience possible with the result that most in any format have setting that are wrongly set somewhere,sometime it is on the monitor,the game ,the tv,the os,the gpu!see all the variable here .we dont talk i vs p here we talk only various setting that can affect both side of the fence!then add the streamer and you can see why we get so much different artifacting!

also another thing that affect and still very much affect any screen is response time!if you got a modern hdtv the artifacting issue will be nil!i am talking 23 inch here!at 40+ inch yes go for 1080p!but at 23 inch (the standard size for hd!1080i is very good!another advantage n insane lot of tv channel on the web are at 1080i!and remember this:this all happen faaster then your eyes can blink!there are issue dont get me wrong but it is because of bugs that were never polished!and contrary to popular belief the vast majority cannot afford 1080p web!and most dont want to be at 720p !1080i is the best compromise in my view!

1080p = 1080 lines per second --> EVERY second all the lines are refreshed 50 times (Europe)/60 times (USA)--> resulting in lot's of data to be calculated per second

1080i = 540 (half of 1080) lines per second --> second 1 = lines 1, 2, 3, ..., 539 and second 2 = lines 2, 4, 6, ..., 540. Second 3 = lines 1,3,5,... and second 4 = lines 2, 4, 6, ... again. ETC... --> Resulting in half the data to be calculated per second

That's why most TV stuff is 1080i and not 1080p (it's only half the bandwith used)

PC's can do 1080p cause they only send from PC to TV/monitor and do not saturate the TV grid

And to compensate that "loss" they cranck up the refresh rate of the TV's

It used to be 50Hz (Europe), than they raised it to 100Hz TV's and now some (like Sony) uses MotionFlow Technologie and boost it up to 200Hz.

Plasma's can go up to 600Hz...

(But don't think you'll be able to play at 100-200 or 600fps that's not the same frequency )

It's just how you look at it... If you do the math one can say that 720p (effective 720 lines PER sceond) is better than 1080i (only 540 lines per second)

But because it switches so fast (for the eye) it isn't noticable (except fast moving horizontal stuff perhaps...) you'd better stay at 1080 i or p (pwould be best offcourse)

Cause the higher the res on the same screen is more pixels on that screen thus better image.

Here's an example (in Dutch) on "how" you can "look" at it (understand it)

I think it depends on the native resolution of the screen


CRT's will do interlaced better

My CRT HDTV does 1080i nicely (853x1080i) supports 480i/480p/720p /960i (480p upscaled )



while
LCD's do progressive scan better.


Plasma handles both good but

still has burn in issue and uses too much power
even on newer sets
