Only different types of HDMI cables can support different versions of HDMI.\u00a0<\/p>\n\n\n\n<p>Different HDMI versions have unique performance standards, and an HDMI cable must be high-speed enough to be compatible with that particular version.<\/p>\n\n\n\n<p>For instance, HDMI 1.4 supports 4K resolution @ 60 Hz. An HDMI cable to support such HDMI 1.4 performance should have a high capacity, and those cables fall in Category 2 HDMI cables.<\/p>\n\n\n\n<p>Also, as an HDMI cable is backward compatible, an HDMI cable that meets performance standards for higher versions can support older versions of HDMI.<\/p>\n\n\n\n<p>In contrast to Category 2 cables, Category 1 or standard HDMI cables come with a lower capacity and, thus, do not support 4K resolution signals. It only supports 720p and 1080i resolutions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"eaedee\" data-has-transparency=\"false\" style=\"--dominant-color: #eaedee;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"419\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/1-30-jpg.webp\" alt=\"A Gold-plated HDMI Cable\" class=\"not-transparent wp-image-10127\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/1-30-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/1-30-300x126.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/1-30-768x322.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">A Gold-plated HDMI Cable<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"then-why-are-some-hdmi-cables-known-as-certified-4k-hdmi-cables\">Then, why are some HDMI cables known as certified 4K HDMI cables?<\/h2>\n\n\n<p>It\u2019s only a marketing strategy.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.clooms.com\/hdmi-cable-in-and-out\/#more-10084\" target=\"_blank\" rel=\"noreferrer noopener\">Input HDMI port<\/a> on display devices like TV or projector and the output HDMI port on source devices like Blu-Ray player or game consoles defines the different versions of the HDMI interface.<\/p>\n\n\n\n<p>An HDMI 1.4 version can support a resolution of 4K @ 30-hertz refresh rate, while an HDMI 2.0 version supports a 4K resolution @ 60-hertz refresh rate.<\/p>\n\n\n\n<p>You must know the HDMI version of your device\u2019s port to know if the video connection supports a particular resolution and refresh rate.<\/p>\n\n\n\n<p>There are no HDMI cable versions as they do not integrate circuits or software that can be updated with time. They only have wires to carry signals from one port to the other.<\/p>\n\n\n\n<p>However, the inside wiring and the wire\u2019s quality may determine an HDMI cable\u2019s performance standards.<\/p>\n\n\n\n<p>So, it\u2019s clear that there is no 4K HDMI cable. You can categorize HDMI cables as high-speed cables that support HDMI 1.4 specifications (4K @ 30 hertz), and there are premium high-speed cables that support HDMI 2.0 specifications (4K @ 60 hertz).<\/p>\n\n\n\n<p>People commonly refer to<strong> high-speed and premium high-speed HDMI cables<\/strong> as 4K.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"e8e7e6\" data-has-transparency=\"false\" style=\"--dominant-color: #e8e7e6;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/2-23-jpg.webp\" alt=\"A braided HDMI cable\" class=\"not-transparent wp-image-10126\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/2-23-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/2-23-300x200.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/2-23-768x512.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">A braided HDMI cable<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"is-it-essential-to-have-hdmi-certification\">Is it essential to have HDMI certification?<\/h2>\n\n\n<p>Yes, it is necessary to have HDMI certification, as buying a cable not tested and certified by these HDMI ATCs may not work as expected.&nbsp;<\/p>\n\n\n\n<p>HDMI LA (Licensing Administrator), a body by HDMI Forum, authorizes some centers known as HDMI ATC (Authorized Test Centers).

For a standard TV, the refresh rate is 60 Hz, which easily matches the video\u2019s default refresh rate, i.e., 60 Hz or 24 Hz.<\/p>\n\n\n\n<p>However, some modern ultra-high-definition televisions have a higher refresh rate up to 120 Hz. In such a situation, the television creates new frames, delivering each frame multiple times. <\/p>\n\n\n\n<p>As a result, you experience less blurriness in videos with swift movements when you are in video games and other sports.\u00a0<\/p>\n\n\n\n<p>So, when the television has a high refresh rate, you must pick an HDMI cable with higher bandwidth to carry the high amount of information required to fill those multiple frames.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"some-tips-for-fulfilling-the-4k-experience\">Some tips for fulfilling the 4k experience:<\/h3>\n\n\n<ol>\n<li>If you bought a television with refresh rates higher than 60 hertz, you must have purchased it for playing online games or other sports to experience smooth video movements. However, to watch regular content without too many fast actions, you must reset the refresh rate to 60 hertz to experience real images.<\/li>\n<\/ol>\n\n\n\n<ol start=\"2\">\n<li>HDMI cables can also support various color spaces defined by ultra-high-definition videos. The broadest range of colors is supported by HDMI 2.1, followed by HDMI 2.0 and HDMI 1.4.<\/li>\n<\/ol>\n\n\n\n<ol start=\"3\">\n<li>Your devices must support the HDMI version that you want to display. For example, if you wish to have an HDMI 2.1 version, your source and display device must have an HDMI 2.1 supporting capacity. You can check that by checking the HDMI ports on these devices. Now, imagine if your devices support different HDMI specs. In such a case, your display device will display features of the lower specs. For instance, if your Blu-Ray player has an HDMI 1.4 port and the monitor supports HDMI 2.0, the monitor takes features of the HDMI 1.4 version. If you want to avail of HDMI 2.0 features, both devices must have HDMI 2.0 support.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"cfd0d1\" data-has-transparency=\"false\" style=\"--dominant-color: #cfd0d1;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"563\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/3-11-jpg.webp\" alt=\"A Standard HDMI-to-Mini HDMI cable\" class=\"not-transparent wp-image-10125\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/3-11-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/3-11-300x169.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/3-11-768x432.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">A Standard HDMI-to-Mini HDMI cable<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"is-using-a-4k-hdmi-cable-on-a-non-4k-television-okay\">Is using a 4K HDMI cable on a Non 4K television okay?<\/h2>\n\n\n<p>HDMI 1.3 cable is a non-4K cable as it does not have the required bandwidth.&nbsp;<\/p>\n\n\n\n<p>However, the next version, i.e., HDMI 1.4, has similar bandwidth but can transfer 4K videos at 30 frames\/sec.<\/p>\n\n\n\n<p>HDMI 2.0 cables and its other types have bandwidth over 18 Gb\/s, which is okay for 4K content at 60 frames\/sec.<\/p>\n\n\n\n<p>Further, HDMI 2.1 cables can support a 120-hertz refresh rate and 4K resolution high-definition video quality.&nbsp;<\/p>\n\n\n\n<p>Apart from the bandwidth, all cables\u2019 compatibility and design are the same.<\/p>\n\n\n\n<p><strong>High-speed\/HDMI 1.4 or higher cables<\/strong> have a higher tier to work with all display resolutions except 8K.<\/p>\n\n\n\n<p>On the contrary, other HDMI versions do not have such high bandwidth to transmit large data packets with 4K pictures.<\/p>\n\n\n\n<p>As HDMI cables show backward compatibility, HDMI 1.4 and other latest HDMI cables easily support 720p, 1080p, and 1440p resolutions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img data-dominant-color=\"c0c0bf\" data-has-transparency=\"false\" style=\"--dominant-color: #c0c0bf;\" loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/4-4-jpg.webp\" alt=\"A DVI-to-HDMI cable\" class=\"not-transparent wp-image-10124\" srcset=\"https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/4-4-jpg.webp 1000w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/4-4-300x200.webp 300w, https:\/\/www.clooms.com\/wp-content\/uploads\/2023\/08\/4-4-768x512.webp 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">A DVI-to-HDMI cable<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"conclusion\">Conclusion:<\/h2>\n\n\n<p>So, all HDMI cables are 4K ones except HDMI 1.0, 1.2 and 1.3.
