Well if you do amir will want to come round and measure the resultsI'm buying one of these.

we need to understand what's going on in the brain when you swap cables out etc . You can't rely on humans interpretation of what they see or hear.
Hi
Pause a disc or whatever , take a pix of screen with super duper HDMI cable ... then remove super-duper, put no-duper cable take another picture of screen. Send Pixes.
Simple .. Data points.
This is where properly designed, bias controlled, testing comes into play. It attempts to address your very good point.
The point being is since the brain knows that a cable has been swapped out cognitive bias is present and pollutes the results.
Yes and a lot more going on than that too. It sounds a bit far fetched but you have to observe the mind before our conscious interpretation. All sorts of factors come into play psychologically, not just acoustic related factors. I would be confident that people under test conditions will behave and respond differently compared to when they are in thier own homes.
What we hear when relaxed and in familiar surroundings or more precisely how we consciously interpreted the music will be different to being under test conditions Imo.
Anyway this is the measurements area, and I am sure my ideas will fall on deaf ears
I am fascinated by audio measurements and how they relate to the subjective experience but nothing here seems to be addressing this.. It's all abstract, only relevant purely academically. It's like watching a episode of ' the knick' lol
You mean like a room full of people at a show where AudioQuest is swapping out Ethernet cables and a bunch of people hear a difference?
Then I agree. But you also have to be willing to concede the point that it can indeed be done. Sauce that is good on goose is equally good on gander.
So you are admitting that the difference might be in your head?
I'm all for ideas. Opinions are just opinions. I'm after data. Again you have a cable that you admit makes a difference, that you aren't using and I'm still willing to pay the round trip postage. I would hope that your participation here would go beyond the chair and keyboard.
Data lol
Not got through to you
I write, you read but the data you should be able to understand seems to be not compatible with your language matrix. I won't burden you with any further data, you have maxed out already
Jinjuku, can you check to see if your graphics adapter enables HDCP even in non-movie content? The reason I ask is because if that is so, we can use an HDMI capture card and grab the image bit by bit with a test image. Camera images are harder to use in this manner. My fear is that HDCP is always asserted but if not, we have a way to capture everything and post for comparison here without a trip through analog capture of the camera .
Of course you seem to be making the assumption identical pixel values display the same. Even more so than with audio this would be true enough. I can also be sure someone will say it is not.Jinjuku, can you check to see if your graphics adapter enables HDCP even in non-movie content?

I see your point .Of course you seem to be making the assumption identical pixel values display the same. Even more so than with audio this would be true enough. I can also be sure someone will say it is not.
Not the ones I have. Which capture card supports HDCP and will let you save unprotected video?HDCP handshake is supported on capture cards and is independent of what is coming across the wire. HDCP is always on.

I know that. And my intent was to use a still test image. The problem is that I think HDCP will be asserted by the graphics card regardless. If so, without a cheater card you can't capture it. Do you have confirmation of any graphics card solution which only asserts HDCP on protected content that requires it?You could also get un-protected H.264 video... Just a thought.
Good point. HDMI is a very finicky communication link and you should use quality wires. With certification voluntary (and cheating prevalent) buying cables from likes of AudioQuest is actually a good thing. We are discussing here whether there are additional benefits beyond that.I don't own AQ HDMI cables, but I do own both a cheap version and a far more expensive "videophile" grade version. The more expensive cable, apparently, offers superior shielding. While picture quality looks identical with either; using the cheaper cable interferes with the over-the-air signal. Careful attention to cable dressing helps, however the more expensive cable is far less prone to interfere.
