The HDMI cables were introduced over the past two years and aimed at helping the end-user get the best picture and audio possible from their existing audio system. And, the Perkune HDMI cables considered being amongst the best audiophile cables online. I always enjoy the comments, and email received from satisfied customers, and some observations can be quite revealing.
The longer an HDMI cable is, and the higher the data rate to be carried (e.g. 4k; UHD), the more errors are caused by the HDMI cable. Therefore, especially with longer HDMI cables, it is essential to pay attention to quality (cross-section, conductor material, shielding, etc.).
The continually growing range of Ultra-HD TVs and monitors poses not just the question of the right content, but also the proper connection. Full HD has been part of the mainstream for some time, but now Ultra HD is conquering the current market landscape with an even better format (four times the resolution of Full HD). Excellent – because for the best image, you simply can’t have enough pixels. But how does this affect the connections between the new components?
He HDMI organisation has released a new HDMI 2.0b standard. The main difference is that the new standard supports the HDR (High Dynamic Range) format. HDR improves the contrast ratio because the source sends additional information (metadata) to the television – information that regulates the television’s backlight. The origin and TV must, of course, also support HDR. It also supports dynamic synchronisation between video and audio streams. This new standard does not require a new cable type! That means that high-speed HDMI cables with Ethernet are still suitable. There are also no resulting changes to the categories of these cables.
The HDMI specifications of the HDMI organisation fundamentally differentiate between two versions: Standard and High Speed or Standard with Ethernet and High Speed with Ethernet. The High-Speed versions allow for a higher data rate, which is especially necessary for 4K formats. The Standard text is thus a non-starter for the transfer of 4K formats based on its limited data rate. Also, it is essential to watch out for differences in cable quality as relates to manufacturing, material and shielding.
Potential pixel errors notwithstanding, necessary wiring may work for shorter cable lengths. But, the difference will become apparent in the case of longer transfer distances. A build-up of pixel errors results in image interference and picture loss. There may even be no connection to begin. The key to a suitable cable is proper shielding and a sufficiently thick copper signal line, not necessary copper-plated aluminium wiring. And, allows for the adherence to the impedances of the data cables and ensures flawless manufacturing in the connectors.
At Perkune audiophile cable we are continually improving all our cables. As technology changes, we too will change, And, bring you the latest and best value for money audio cable. But you will see and hear the difference in performance when you install the HDMI cables from Perkune!
