I was under the impression that 1.3 has the capability to give you 3D but at a lower resolution. Essentially splitting the 1080 signal into 2 (540 for left eye and 50 for right eye), giving you a lower resolution 3D.

HDMI 1.4 will give you 1080 right/1080 left..... among other things.

The other thing I read (I think) is that off axis viewing of 3D is pretty poor.

Anybody here remember watching the red/blue 3D karate films back in the 70's? Or the album cover for Grand Funk Railroad's "Shinin' On" with the punch-out glasses?
I just can't believe we're going through this all again 30+ years later; I mean sure, technology has improved and all but let's face it; the only thing that will really make us feel 'in the moment' was some of that brown acid going around the front 3 rows.....

Oooops, I've said too much.

Actually I haven't even seen a 3D film yet- supposed to go next week to see Avatar (GF is dragging me) so I suppose I should reserve judgement until afterwards. But I don't have high hopes...

Dont tell me I have to now upgrade to 1120p???? lmao

I know this has been posted here before, but it's worth another post. See this article: [Link: hdguru.com]

It really helped my understanding of 3D. There is nothing special about 1.4 cables in relation to 3D - the reason current receivers won't work is because of the EDID information stored on the chip. The PS3 will work because the EDID information can be updated.

Thanks for the link, Royd. That's very helpful.

The last time I checked the info at [Link: hdmi.org] they were listing 7 different competing standards for 3D:

•field alternative
•frame alternative
•line alternative
•side-by-side half
•side-by-side full
•L + depth
•L + depth + graphics + graphics depth


This was BEFORE the 1.4a update which added at least 4 more standards to cover the broadcasat stations. We can't even begin to wrap our hands around 3D until a winning format rises above this insanity. Consumers will be purchasing a 3D title in a format that is not compatible with their screen/player/AVR and will want their A/V pro to make it work! This makes the HD-DVD / BLU-RAY format wars look like a minor scuffle.

you don't understand the info. The disk has 2 streams, yes those two streams need to be "combined" to be sent to the TV and displayed properly, but it does not matter. It is a lot like 1080p, 1080i, 720p ... did they need to "standardize" on only one resolution? No, the player/display handshake and decide what is best. You need different ones because of different display types/designs and the issue that 3D was implemented on some HD ready TVs. At CEDIA last year JVC showed a TV that used polarization with alternate lines (i.e. each line had the opposite polarity so one eye saw the even lines and the other the odd ones), on the other hand some other TVs use shutter glasses, so you need the different frames. At worst (for the consumer) you need to match the display and player, but my guess is that most players would just be able to do any one of them (or at least most of them), and if there are issues, then that is better for CI right (i.e. average Joe won’t know what player to match to what TV)?

Royd! Good to see you on here.

I need to pick your brain tomorrow about constant voltage systems. I will be calling.

SHHHHHH.... don't tell anyone else, it's not out yet ;)

Never said I could add =)

Currently watching 3D on the Samsung UN55C8000 using a 10 meter Honeywell CureLight cable. No problems so far. I don't know of anything in the 1.4 standard that relates to 3D.

Can anyone explain?

The cable does not need to be 1.4 to pass 3D - it just needs to be a good quality cable that can support the bandwidth needed. 1.4 cables would only be needed to support the ethernet channel.

The source and display need to have 1.4 to support 3D.. and the any devices in between (such as a receiver ) would need to be 1.4 s well.

If the cable does not need to be 1.4, why does the AVR need to be 1.4?

The old receivers did not have any EDID information stored on the chip to support 3D since those standards did not exist at the time. So on a receiver with HDMI 1.3 when it sees the EDID info that says "I can do 3D" it doesn't know what to do and can't pass that info back and forth between the source and display.

Thank you. Your response actually makes sense.

3D TV. Why buy 3D TV when getting a tattoo of glasses on your face hurts just as much, makes you look just as stupid, and costs far less?
