Eizo are not a company highly interested in releasing products that they believe are less quality but cheaper. They like to maintain their status as a company with superior colour representation for computer graphics design.

Sorry, I failed to mention that.

I did mention that a poor HDMI cable will be more likely to break and will just not work leaving a blank screen. I've heard that if you have a very long HDMI cable that is very cheap you can get artefacting, but it isn't really a drop in quality, the artefacting is more like coloured blotches and sparkles. Anybody who has this won't think that the image quality is poor, they will think that something is seriously broken.

It's a possibility that he is mistaking an anologue cable for a HDMI cable, but given his post history, I doubt it.

Best "overall" t.v's are Plasmas. I'd go with Plasma for gaming as well.

It's rather strange like you say as I do wonder what he means by obvious quality differences.  It's just impossible for the picture brightness, colour, contrast or sharpness to be different across two HDMI cables, like you say, it's artefacting that occurs.  The only possible theoretical solution I can think of is if somehow one cable was faulty to an extent that it caused some sort of weird grounding issue that affected the TV's input circuit but I've not ever really come across it before and such a faulty cable might affect TV's differently.  I personally bought a cheap Chinese 10m HDMI cable for my projector and the picture quality is perfect so I don't worry myself about them.  I do have a hideous 10m VGA cable mind you that was bought cheaply and is terrible for ghosting.

Have you read what I wrote ? Plasma is not qualified for replacing LCD Monitors. Eizo makes high res Monitors thats impossible for Plasma 1080p is the max the pixel density is just superior for LCD but that doesnt matter for TVs and until a couple of years ago manufacturing smaller screens than 50 inch was hard.

The Colors are good for Plasma but CRTs beat both technologies in that regard.Where Plasma shine is the infinite contrast and reaction time. 

@Slowmo.

Ofcourse you are right that there are benefits to more expensive cable. Cross Talk shouldnt happen even for the cheaper cables and if the signal doesnt come through or just partially it means the cable is broken. But the quality itself cant possibly get better there is nothing to improve.

1) Size... there are no PLASMA display less than 42".

2) Static image... PLASMA is not good or not flexive for static image when compared to LCD... static images is like Windows, Linux, etc.

3) Pixel density... it's impossible to make PLASMA with ultra-high resolutions... the biggest PLASMA resolution (2K and 4K) have 150".

From an electrical engineering standpoint, if the overall impedance across the cable remains constant (can degrade slowly over time, as well as with a lot of wear and tear), and the electrical impedance is lower than the overall allowable threshold, there should be no difference in signal across a cheap cable (tolerable impedance) and an expensive cable (supposedly ultra low impedance).

Picture quality on HDMI can only differ in 3 ways: Perfect quality, interference (represented as blocky interference or complete frame skips if the ECC is too slow to render the entire frame before frameswap), and no signal at all (usually there are too many errors per block that the signal is "uncorrectable"). Changes in colour or brightness is completely false.

I'm not sure if it's an actual physical impossibility or there has not been enough investment towards lowering the pixel density of plasma screens, but I'd be interested to know what professional monitor companies' standpoint is on it.

I've never heard of an infinite reaction time at all. Not even light has such a thing. However, you might be interested to know that some higher-end Eizo monitors are reported to have a higher colour fidelity than CRTs.

I dont know the details but it seems they have massive trouble increasing pixel density on plasmas if not there would have been atleast showcase TVs.

Infinite response time is exaggerated but 0.001 ms. thats 1 nanosecond 2000 times faster than the fastest LCD who has afaik 2 ms.

Thats practically infinite for a human since thats way faster than the human brain can theoretically work. Even 10 Nanoseconds or 100 are fast enough. And in 3D it makes an even bigger difference than in 2D.

Infinite Contrast is logical. If you turn a pixel off its infinetly darker than one who still shines.

Regarding Colors Plasmas usually win in that regard too but its not as superior to LCD as in other points. Eizo seems to be the best you can possibly achieve with LCD right now, when it comes to colors, after I looked into it. But something tells me that LCD/LED TVs arent that good.

I can second this statement.  I bought an HDMI cable on Amazon for like $3.20 after shipping or some crazy cheap amount like that (it was brand new).  It would work for like an hour then completely cut out, then work for about 5 minutes, then just cut out for good.  Every time I tried using it, no matter what device or tv it was with, this happened.

While I didn't go out and buy a $100 cable (I knew that would be stupid because it will not make a difference), I spent like $20 on one that I knew wouldn't do the b.s. that my first one did.
