Let me preface this by saying thank you. Thank you for being, and thank you for the amazing support, stories and advice you provide on this forum. For Tech junkies (novices) like me, I can read the specs, and understand them to a certain extent, but you all give context and better references than the convoluted jargon used on product websites.
As such, I researched. And researched, and researched. Looking into my first HDTV since 2009. After a long selection process, I narrowed it all down, canceled out the Sony, the Vizio and the LG (non-OLED... if I had OLED money, I wouldn't worry so much) and got a 65KS8000, with a 790 for sound and an XB1S for the developing UHD BR scene. Unfortunately, my wife is a bit of a worrywart when it comes to big-spending online. (If I could have used Crutchfield or B&H on this, again, different conversation)
So I'm forced to buy in person at Best Buy. I cut in and move like a raptor, sights trained on my prey and start ordering components by the SKUs I looked up online. No need to talk out options, I have done my homework. Funny enough how many people point out how these BB salesmen try to push the Sony's, I was nearly offended at how they were ramming the 850 and 940 down my throat.
I get to the end of it all and the clerk asks me what HDMI cables I want. Having thought I did all the research on what I wanted, I knew I would hook this all up myself, so I told him I was ordering some that I had found on Amazon.
I didn't want to get accosted into another Monster purchase, as I was 7 years ago, only to read all my education meant nothing, and the mean man at Best Buy made me quite the fool that day.
I should add, I cave when cornered.
And so, this new and improved meanie cornered me, and sold me on the very different but equally expensive, super-sounding, silver-tipped AudioQuest Chocolate cables.
A little uneasy, I went home, angry because I for sure got taken again on cables I could have got for 1/5th the price online, but nonetheless happy because I knew the 4k HDR goodies that awaited me. (Still waiting, delivery expected tomorrow)
BUT, but, BUT, I get home and look at all the items I was able to bring home in the car, and get to the HDMI boxes only to see they are essentially 1.4 cables. They have all the right wording on there - 18Gbps, 4K, 3D support, 4K@60Hz, ARC, 2.5% silver-tipped for better audio, less distortion, etc.
Darned thing is, it never specifies what quality cable it is certified to be. It says "can work with HDMI 2.0" products to deliver 4K picture, but I also told the BB guy I'm looking at 2.0a capable wiring as well for HDR-support. (And 2.0b if you got it, sure... I'd love me some dynamic HDR metadata) And he handed me this box.
My question after all this (truly, god bless you heroes, you Cadillacs of men, if you reply to my needlessly long post) is, what's the difference? Not functionally, because I got that from all the literature. But, are there different cables? Because on the one hand, a majority of posts say no, the same data is carried over new expanded channels in 1.4 cables. But then I read about the exclusive capabilities of 2.0 and 2.0a when plugging in only 1.4-capable wires into 2.0 supported televisions, etc.
Are there different wires? Are the AQ Chocolates I got no good for me and my HDR-dreams? Are the Amazon ones I chose any better? Are 2.0/2.0a cables and of you find good, or worthy of recommending?
I very much appreciate your time and look forward to becoming a more engaged member who doesn't mooch as much.
