Hdmi 1.4 vs. Hdmi 1.3

no it doesnt improve anything, it only adds features like 3d support and higher resolutions among other things

idividebyzero is correct, besides 3D, which I beleive was supported in 1.3b, 1.4 gives the cable capability of transmitting 4k resolution.

There is no such thing as 1.3 or 1.4 HDMI cables, there is standard-speed, and high-speed. High-speed is recommend for 1080p and needed for 3D.
What is full Blu-Ray?

I want to know the same thing.

I have a PS3 and an HDMI 1.3 cable. 3D blu-ray doesn't work with this combo.

However my nvidia GTX460 is able to do 3D perfectly on this tv with the exact same cable once the 3DTV play software is installed with Arcsoft TMT5.

How is this possible? The TV is a 1 year old Sammy 3D plasma.

Actually according to nvidia HDMI 1.3 cables can support the HDMI 1.4a mandatory 3D formats:

"What is the difference between HDMI 1.4 and 1.4a?

HDMI 1.4 requires that 3D TVs support the frame packing 3D format at 720p50, 720p60 and 1080p24 or 720p60 and 1080p24. HDMI 1.3 cables can support the mandatory HDMI 1.4a 3D formats. HDMI Licensing LLC recently announced the HDMI 1.4a specification, which adds two mandatory formats for broadcast 3D content: Side-by-Side Horizontal and Top-and-Bottom. The mandatory HDMI 3D formats are now:

For movie content:
Frame Packing:
1080p @ 23.98/24Hz
For game content:
Frame Packing
720p @ 50 or 59.94/60Hz
For broadcast content: (NEW IN HDMI 1.4a)
Side-by-Side Horizontal
1080i @ 50 or 59.94/60Hz
Top-and-Bottom
720p @ 50 or 59.94/60Hz
1080p @ 23.97/24Hz"

I own one of the GPUs listed above and the product specification states it supports HDMI 1.3.

The HDMI 1.3 interface on the NVIDIA GPUs can be programmed to support the mandatory HDMI 1.4a 3D formats. Also, a DVI port on the PC can be programmed to output the mandatory HDMI 1.4a 3D formats, and can connect to a 3D TV using a DVI-to-HDMI adapter.

Theres a version of HDMI 1.3 that is basically 1.4 as they used it to test features 1.4 would have, it supports most of the same stuff like 3d. Either 1.3b or 1.3c supports everything 1.4 does except the weird stuff like ethernet. Most 1.3 HDMI cables sold should support 3d.

(I dont like saying "high speed", thats extremely vague marketing speak and easily abused, who knows how many old HDMI cables were marketed as "high speed" because they had more bandwidth than component/VGA. Changing the name was a stupid idea and to make things worse they did it after the fact that they were officially calling it 1.4)

In theory, a "high-speed" (f/k/a HDMI 1.4) cable is the one specified for use
with 3D.

In practice, if you're getting 3D from your existing HDMI cable, switching to a
high-speed cable won't make any difference. However, since a 6', high-quality,
high-speed HDMI cable should cost less than US$10, maybe it wouldn't hurt
too much to switch.

Again, there's no such thing as an HDMI 1.3 or HDMI 1.4 cable, there are "Standard" (category 1) or "High speed" (category 2) HDMI cables. HDMI versions (1.3, 1.4, 1.2, etc) are referring to the protocol that is used over that cable, the capabilities and communication that go on between (for example) TVs and players. Some HDMI 1.3 or 1.4 features may require bandwidth beyond what is tested/guaranteed with a "Standard" (category 1) HDMI cable, but that doesn't mean they won't work.

Further the category/speed of a cable is a guarantee of minimum performance. There is nothing that says a Standard HDMI cable can't do 3D or 1080p, the fact that it's "Standard" just means it either wasn't tested to High Speed standards (or possibly failed).

The wiring/pinout of Standard and High Speed HDMI cables are identical, there's nothing different, the only difference is the level of testing they passed, the guarantee of performance that comes with them.

Just as an example, according to HDMI:
http://www.hdmi.org/learningcenter/faq.aspx#49

Standard, Category 1, HDMI cables are tested to approximately 1080i. So you might think that that would mean you need a High Speed cable for 1080p. Well I have two 50' Monoprice HDMI cables that happily carry 1080p60 all day long despite the fact that you can't even buy a High Speed cable that long (the longest High Speed HDMI cable is 25')

So there, remember the Category of an HDMI cable is just a guarantee of minimum performance, not a ceiling or a maximum. I look at it this way, if you're buying a new cable, get a High Speed one just to be sure it will work, but if you've already got a Standard HDMI cable that's working fine, there no gain replacing it.

Nevertheless with my standard cable the PS3 refuses to do 3D, but the PC can.

If one device can do 3D but the other can't, with the same cable, it's likely due
to a minor electronic differences in the how the HDMI transmitters and receivers
work. In these cases, using a cable with a different length makes it work.

How can I tell whether my cable is standard or hi-speed?

You'd most likely have to look at the documentation that came with it.

If your cable does what you want it to do, it's not important. If you're interested,
I'd examine the cable heads and possibly the manufacturer's web site (unless
you're buying generic HDMI cables like I do.) Failing that, a new 6', high-speed
HDMI cable from Monoprice is less than US$4.

Or your choice of about 50 different high speed HDMI cables of various lengths for $3-10 at Amazon.

If you really want really good, name brand ones, Amazon also sells the Acoustic Research Pro III for less than $15 (others sell them for $60-80).

Personally, I see no reason spend more than $10 for an HDMI cable.

not sure what you mean by timing and noise - but if you spent more than max $10 for that cable you wasted money.

But don't confuse higher prices with higher quality.


An HDMI cable isn't 'worth' more than $5-$15 even if the manufacturer places
a much higher 'value' (i.e., price) on it.


"Pixel noise", if I understand what you mean, can easily be a symptom of a
marginal or defective HDMI cable. Replacing it was the right thing to do.


At $120 list, the price is about 20 time the value. However, if it works, who
cares? It's not like you have to pay $120 every month.


In the end, you replaced a cable that wasn't good with one that was good.
It's not clear at all that HDMI 1.4 helped. It's clear, however, that a cable
that says "Monster", "AudioQuest", or whatever is no better than any other
similar cable.

Yes. Brighter ain't always better.



Gee$400 bucks for a cable...might just be better to get a calibration at that price! Lol

It's physically impossible for an HDMI cable to make video brighter or dimmer.

Marginal or defective HDMI connections show up as symptoms like 'pixellation'
(macro blocking), stuttered audio and/or video, or a signal which the HDMI
sink can't decode at all.

I have a bunch of monster hdmi cables and even chocolate ones (relatives got em for me) They all look the same to me when compared to my $5 monoprice cable

If you like the expensive cables go for it. I'd just recommend not buying any of the cheap ones from amazon. Mono or BJC all the
way for me

Good article to help people understand hdmi cables
http://news.cnet.com/8301-17938_105-...-are-the-same/

You're right, they're not all the same, there are Standard, and there are High Speed certified ones. And of course there are just plain bad ones that don't work.


It is utterly impossible for an HDMI cable to make a difference in brightness or colors or anything of the sort.

OK, admittedly it is possible, but at 2 million pixels per frame, 24 or 60 frames per second, the probability that each pixel in each frame would fail and be recognized by some common difference (ie all 5% darker) to what it should be is essentially incalculably small.

Digital signals make it or don't. Look at broadcast TV, it either works 100%, or it doesn't and it's completely obvious (blocking, pixelation, or no picture at all). They don't get dimmer or less colorful as the signal weakens, then just start failing spectacularly. If a pixel is supposed to be a value of 100, and the signal is too weak, it gets interpreted as some basically random value, like 230 or 20.

Digital transmissions don't fail/degrade gradually like analog ones, they work, down to a point where they simply don't anymore, and when they don't it's obvious not subtle.


You need to reread what's been said, no one is saying all HDMI cables are identical, what's been said is that if one HDMI cable works (no pixelation, no sparkles, etc), a "better" HDMI cable, a more expensive one will not make any difference. It's not going to make your picture brighter, or more colorful.

Let me ask you this, is This Cable going to make my printer print any better, will my prints have more contrast, better colors than the "free" USB cable that came with it? It's the same situation with HDMI.

There is, however, no correlation between quality and price. None.


HDMI cables

• don't make the colors clearer
• don't make the colors muddier
• don't make the video brighter
• don't make the video dimmer
• don't make the audio better
• don't make the audio worse
• don't cause ghosting

The only differenct to the end-user is the loss of $45 for an overpriced cable.

I too overstated my case saying it was 'physically' impossible.


Plus, the cable would have to leave all the audio and control information
untouched while borking only those particular bits of video. I think a
fair (if invented) analogy would like tossing a coin and having it come up
heads billions of billions of times in a row.

Could it happen? Absolutely. Does it happen? Maybe once by the end of
the universe.
