Yeah, get back to me when you can pull a 1080p signal from the wall.

Get it right from my cable company.

Which cable company is that?

I've bought digital cable from 2 different companies and all I ever got was 1080i and 720p.

Read the link. 1080i = 1080p for most content (24 frames). Live events and high quality shows are shot in 1080p/30, carried via 1080i/60 and then fully and perfectly de-interlaced back to 1080p/30. That's why discoveryHD and sporting events look so good.

You don't have to transmit 1080p to get fully, pufect, identical 1080p frames.

Hell, pulling any video from a wall is pretty impressive.

Everybody on this board should read this. It spells it out very clearly and with nice illustrations.

It's 2007. The year of 1080p HD.

At the end is a nice section about scaling to 1366x768 and why it sucks.

GAAAH.

1080i is the same as 1080p once you deinterlace it. It's the exact same on every modern display.

pretty sure he is blowing smoke....there is no way cable can support the bandwidth needed for 1080p programming...are there even any cable boxes that output a 1080p signal?

if he can provide a link, I will humbly admit my error....

The link is in this thread. How many times does one have to beat people over the head with the fact that 1080i = 1080p (for most content).

 

[waggy]

yeah 1080P is sooo over rated 😛

Excellent article. This helps to clear up a lot of confusion. I've always heard that 1080i is not necessarily inferior to 1080p, but most articles I've seen are too heavily worded with techno-babble for me to understand what they're talking about. Pretty pictures always help. 😉

So do many Tv's de-interlace the 1080i signal?

And that is why I stand by my statement. 😛

[TheAdvocate]

I'll answer it this way - there are no more 1080i TVs... any of the ones still being sold are legacy models. If it can do 1080, it displays at 1080p, even if you feed it 1080i. It just deinterlaces it and it ends up being the same displayed signal as 1080p due to the framerates.

Ah i see, so the people who say that 1080P Tv's are useless are wrong?

More than wrong. Completely cluelees as well as deap up misinformed and unknowlegable.

The posted article shows what I've been trying to say ever since 1080p displays came out.

Why can't an LCD display 1080i?

Why don't they broadcast in 1080p?

I think Bandwidth Issues

We've been over this. They're the same because 1080p is 30fps.

That's a bit of an oversimplification. But the link does a pretty good job of explaining the reasons this is not actually the case all of the time.

Also, there were a lot of 1080P tv's sold in the beginning that improperly de-interlace which actually results in a picture inferior to 720P.

 

[dwell]

Don't look for the 1080i interleave lines or you will always see them. I wish I had taken the red pill.

 

[Shawn]

If you have a true 1080p set then 1080i! Otherwise you are scaling the picture.

 

[pennylane]

1080p vs 720p on projectors

It's a good read. True it's projectors and not TV's, but still. 720p can look very good.

I'd pick 720p over 1080i. I think scaling is easier to do than deinterlacing. Of course this probably varies from set to set and you're best off trying both and seeing which you like better.

I understand that 1080p is all great, and plays 1080i content better, but why is it that if I compare a Pioneer Elite 50" plasma side-by-side to the Pioneer Elite 50" 1080p plasma, which costs almost twice as much, I don't see much of a difference? An additional $3-$4K would be much better spent on audio, IMO.

Same idea with LCD's. Comparing the Sony S2010 to the Sony V2500, one being 720p and the other 1080p, while there is a difference in color (the V2500, other then 1080p, is a better set all around), doesn't look all that much different, especially not $500 better. Granted, this is all with 1080i satellite, but that's the majority of what people watch today anyways.

And if anyone wants to tell me that HD-DVD on my Fujitsu 63" 720p plasma doesn't look as good as a 1080p set, they haven't seen the power of a Fujitsu.
