Most HDTVs don't handle 1080i correctly... - Blu-ray Forum

AV_Integrated · 10-23-2006, 05:45 PM

In the most recent issue of Home Theater Magazine there was a test of over 50 HDTVs for their ability to accurately work with 1080i material. Two levels of testing included the displays ability to properly process all 1920x1080 pixels across 2 fields of a 1080i source and a test to see how well the displays worked with film based (24 frames per second) source material for 3:2 pulldown correction.

Out of the displays tested, less than half of them properly used all 1080 lines delivered from a 1080i source.

Just over 80% could not handle 1080i film based material correctly.

For those wondering what that means, it boils down to very few HDTVs being able to properly and show film based material when that material is delivered to the display at 1080i.

Or: HD-DVD, since it doesn't yet have a player delivering 1080p, is not realizing the full potential of the source material on over 80% of the displays on the market!

NOT KNOWN: If the Samsung properly handles the 1080p/24 -> 1080i -> 1080p conversion.

NOT KNOWN: How many of the displays tested could handle 1080p sources.

NOT KNOWN: What the exact resolution of all the displays were. I don't think it was limited to 1080p ONLY sources - I'll re-read the article to see if that is mentioned. If it IS only 1080p, then the numbers provided above I would call 'accurate'. If some displays were less than 1080p, then I would throw all of those displays out of the final calculated numbers.

^^ Round 2.

Everyone should take the time to at least look at the graphs, if nothing else.

Great stuff!

Anyone who's thinking about buying a new display any time soon really needs to take the time to look through this stuff.

we preach it at times on here, stick with some of the major companies. of course, even then they don't always get it right.

It's unfortunate that out of all the Samsung models they tested, not one of them was any of the 3 models I own.

That's shite

Clearly I'm going to have to move to a video processor if I want quality. GD shiesters.

This is not really new news, but I am glad it's getting some attention.

Why would any BD player do 1080p/24 -> 1080i -> 1080p conversion? That is ridiculous. 1080p/24 -> 1080p/60 or /72 or maybe even /30, but there is definitely no reason to interlace something just to de-interlace it again.

We see that Pioneer makes some of the best panels in that comparison.

Getting digital stuff all on the same page is clearly a challenge.

I'll make sure I do my homework when I upgrade to the good stuff in the future.

That's what I did when I first red 'bout Blu-ray.

Then I bumped on this site...

But I don't think this is a good situation... I mostly feel unconfortable...
I mean, how will you know for sure with future models?

The problem is that everything is constantly changing and evolving. Just look at HDMI and how many official revisions that has gone through in the last couple years.

The only thing you can do is 1) pick a set of capabilities you feel you need and buy when the technology gets to that point, or 2) pick a point in time and buy the best technology you can get your hands on at that time.

You can always get better technology if you're willing to wait six or nine more months. However, in that intervening time you miss out on what you might have had. It's just a personal trade off.
