I Installed a Samsung 3D set today for a customer, the Guy was as pleased as punch with it until he opened up the several 3D Blu-Ray discs he had purchased to view with it. To my suprise every one was shipped with 4 pairs of old style red/blue cardboard filter glasses. OK I thought to myself, there must be 2 versions of the movie one in old style 3D and one in the newer format.... WRONG, just the red/blue version. What a complete load of marketing drivel.

So just a warning to you 3D adopters, make sure you get the right 3D version of your movie wink

(My next call after that was a guy with a cableHD box connected by a SCARTrolleyes) , im sure this world just loves ripping people off.

This is why I am skeptical of the 3D boom that industry is promoting.

I know of quite a few people who have HD TV but no HD content. People but kit with no idea of the extra bits they need to make it actually work and then are disapointed by the results.

It's like the old story of the bloke who purchased a CD and tried to play it on his record deck. (no idea if this is true).

That reminds me of an article by Barry Fox in Personal Computer World, but the other way round. He went to a presentation by a major electronics company who were talking about their new HD recording techniques. While most of the audience were taken in by the "Emperor's New Clothes" Barry noticed the projector could only display SD.

I'm not mentioning names but someone I know is VERY impressed with his new "HD" set-up whistle

1080p is probably the most acute example of this phenomenon.

Unapplicable in 99% of applications.

how so plotters?

surely if i have a 1080p telly connected to a PS3 and a 1080p movie isn't this relevant?

In most situations, the viewer is sat too far from the screen to notice the difference afforded by the extra resolution.

The limit is not the components but the eye and that's not going to change any time soon.

I doubt that is true, I have a 43" Pioneer and a 42" Samsung, the former is a 720 line set and the latter 1080. Although they both have a lovely picture the Samsung definitely has the edge on picture quality when watching a BD due to the higher resolution.

That said, the Pioneer is much nice when watching SD content, presumably because it doesn't have to upscale to the same extent.

I suspect Plotloss was talking about the difference between 1080i and 1080p though.

There is no discernible difference between 720p and 1080i.

I can assure you it's true. The eye has a limit of accuity of 1/60th degree arc of vision.

From there it's trigonometry.

There are also other significant differences between your Samsung and your Pioneer not just related to the vertical resolution.

While I agree with the sentement the bold is not true in the case of nearly all movies, anything filmed on 35mm or in HD at 1080p25/30. As a decent video processor will take the 1080i50/60 and create perfect 1080p25/30 from it.

So if you can see the difference between 720p and 1080p (big enough screen/ close enough), you can see the difference between 720p and 1080i.

For watching anything recorded to 1080i then I agree you'll no notice any difference.

no he's right there as a 1080i image is rendered using a 720 line tube.
