HDMI cables 2.0 and 2.1  both deliver 4K High Dynamic Range (HDR) at higher refresh rates. However, that doesn't mean you would always get 4k HDR with these kinds of HDMI cables. Interestingly, 4K and HDR are often considered as synonyms. Actually, they are different and complement each other. Pay a little more attention to discover what makes HDR and 4k unique and what you must sort out before purchasing an HDMI cable. This article will help you better understand this key information regarding shopping the right HDMI cable.

4K HDMI Cable for HDR: The 4 Essentials You Need to Know 

Do consider the following factors before buying an HDMI cable.  

1-HDMI Cable Length and Its Role 

Your HDMI cable should range between 1 to 200feet, because as the length of the cable increases, the digital signal transmitting inside the cable may decrease in speed and performance, in some cases may even fail to reach the other end. The standard HDMI cable length is 6 feet. This length is sufficient enough to connect equipments within the room. You can also choose a fiber optic HDMI cableor a Wireless HDMI for longer distances. Generally speaking, there are various cables to choose from, and some are expensive. However, there is an inexpensive way to achieve 4k at a longer length. Scroll down to explore how you can transmit HDMI signals at longer distances. 

2-Do You Need Passive or Active HDMI Cables 4K HDR 

Compared to Wireless HDMI and fiber optics HDMI cables, HDMI active cables are economical. They each contain a chip fixed right next to the HDMI connector. This chip amplifies the signal received from either an external source or an input device HDMI port through the power to the output device. As you can see, these cables could only transmit signals one way (unidirectional).

A passive HDMI Cable, on the other hand, is a standard HDMI cable. If the distance between your input and output devices is within 10 ft, the passive HDMI cable would suit more in this situation. A passive HDMI cable will perfectly show 4k HDR video. 

3- The 18 Gbps Rule: Gateway to 4K HDR 

Have you ever held an HDMI cable in your hand? You surely have. It feels like a dumb pipe waiting to carry “fluid” or, in this case of HDMI cable, digital signal. The pipe with more liquid passing through would extend in diameter. Similarly, an HDMI cable must have at least 18 Gbpsbandwidth, like the “liquid” for pipe, to smoothly transport information from HDMI-In to HDMI-Out. In short, you need an HDMI cable with at least 18 Gbps in order to transport the 4k HDR video signal.

4- 4K and HDR Are Not The Same 

4K is the total count of pixels in your video. Different brands are labeling it with different names. One may call it 4k; others may prefer to tag a 4k UHD sticker. However, the function remains the same: sharp and clear images. 

HDR, on the other hand, is a beautifying technology. The tech defines and illuminates the colors in pixels. HDR gives more visual pleasure when the image contains real-world scenes with dense yellow-colored sunlight and extreme shades of darkness. It is interesting to note that not all content is HDR. However, when the content is HDR and your TV is HDR enabled, you would get better color and brightness. In short, a TV that supports HDR displays bright and dark colors in perfect contrast to deliver lively images. 

What HDMI Cable Do You Need For 4k HDR 

By now, there should be no confusion between these two facts. First, all TVs are not HDR compatible. Secondly, higher bandwidth of at least 18 Gbps is necessary for 4k HDR video content delivery. So, time to unveil the best HDMI cables for 4K HDR video.
