Is there a difference between DisplayPort 1.1 to 1.4??

[WhereHere1]

ok so I was looking at buying a longer DisplayPort, then I came across a site saying that there is not difference between the 1.1 cables compared to a 1.2 or 1.4.

Has anyone actually seen any difference between them?

"Despite what you may read, there is no such thing as a DisplayPort 1.1 cable and DisplayPort 1.2 cable. A standard DisplayPort cable, including the so-call DisplayPort 1.1 cables, will work for any DisplayPort configuration including the new capabilities enabled by DisplayPort 1.2, including 4K and multi-stream capabilities. All standard DisplayPort cables support RBR, HBR (High Bit Rate), and HBR2 (High Bit Rate 2), which can support 4K at 60Hz, or up to four 1080p displays using multi-stream.

While retailers may try to sell you a more expensive cable touting it will provide a better picture quality, we are here to debunk that myth. Contrary to what you may think, the more expensive cable will not give you a better picture quality. DisplayPort uses packetized data, similar to USB and Ethernet, to send digital display and audio data, therefore you either get all of the data or you don’t. Unlike other older video interfaces, you don’t get a “better” picture or other incremental improvements with a more expensive cable. But of course a poor quality cable could lead to data errors and obvious corruption of the video or audio data, but you can avoid such cables, as explained further below."

As far as I understand it there are no display port 1.1, 1.2, 1.3 etc. cables, just display port cables. The only key thing is the cable needs to be certified. See this article: https://www.displayport.org/cables/how-to-choose-a-displayport-cable-and-not-get-a-bad-one/

Here's a list of certified cables: https://www.displayport.org/products-database/?products_category[]=cables-connectors&products_manufacturer=

This information is from the people who draw up the standards for displayport and so it's definitive. Display port 1.1, 1.2 etc. cables is just marketing speak and some uncertified ones are of extremely poor quality and don't work properly no matter what the marketing says. Just get a certified one.
