1080 FP Owners: Can you see an increase in clarity of 1080i broadcasts vs. 720p?

Just a simple question to see how good the technology is coming along. Please share your opinion.


Note to Moderator: there is a reason for the season

It depends on your viewing distance. Inside 1.6 screen widths yes. Outside 1.6 screen widths probably not

yes. 1080i sources tend to be sharper.

I thought 720P was supposed to be better for viewing sports and other fast action shows. Is that no longer true or did I just not understand HDTV?

Just upgraded to a Marantz VP-15S1 from a Dwin TV3. Big improvement in displaying HD content. I'm very impressed. (I don't know if its a higher quality projector, better resolution or a combination of both).

went for a sonyo z5 to a sony vw60 big diffrance in blu-ray and hd dvd.I have 1st row at 9.5 feet and second at 16 feet on a 100" screen.Not a big diffrance in the back row color is better.

It's still true. 1080i deinterlaced to 1080p offers higher pixel resolution, but 720p has less motion artifacts (more temporal resolution) and it scales pretty well to 1080p.

The question that the OP asks is more than just seeing fine detail with 1080i but it also needs to take into consideration deinterlacing artifacts. If a person is watching film content that was originally progressive, then interlaced and broacast as 1080i and then deinterlaced (with true 2:3 pull-down) to 1080p on a display device there won't be much in the way of deinterlacing artifacts (with the exception of motion juddder) and 1080i will probably look slightly sharper if the source material is pristine.

If a person is watching interlaced video content however, there can be very visible motion artifacts that are seen with 1080i unless a high quality deinterlacer is used (something that performs per-pixel motion adaptive deinterlacing for example). Even with a high quality deinterlacer however there can still be visible problems based on bad edits and such that interfere with the expected cadence of the source material and confuse the deinterlacing algorithms.

1080i vs 720p has been a never ending debate but we have 1080p24 now which allows us to have our cake and eat it too (at least for watching 24hz film content).

This poll is actually a bit more than it appears, as it been posted in all of the display forums. So the results can be used to see if there is a difference between display technologies and installations.
The results will be more meaningful if a moderator would make the polls sticky. If not the posts will probably be quickly buried.

Since I own three categories: LCD flat panel, DLP rear projector and front projector I can vote in three separate polls.
Then as time goes on we can examine for any differences between technologies and environments.

Note: try to keep mum on the polls scope in the other forums :)

Notice the plasma distribution is much wider than the FP results here:

The <$3000 FP owners report a much wider variation with a "seldom" category spike:

1080i vs. 720p was a valid discussion for CRT HD screens, but not for digital screens.

Since all 1080 digital displays de-interlace the 1080i/60fps signal to 1080p/30fps, you are actually comparing 720p/30fps with 1080p/30fps.

Nice try, but we must remain true to our namesake.

I'll bet the moderators are enjoying me manually having to coordinate all the polls. All this work and no fun! :rolleyes:

Here are the rear projection results:

If the deinterlacing chips are junk, then the picture is junk, this is in no way related to the display technology used with the exception to CRT.
