As with DisplayPort, it is a digital interface for the transmission of high-resolution video and audio signals.&nbsp;<\/p>\n<p><a href=\"\/blog\/wissen\/was-ist-displayport\" class=\"button\">Good to know: What is DisplayPort?<\/a><\/p>\n<p>&nbsp;<\/p>\n<h2>Applications of HDMI<\/h2>\n<p>HDMI is mainly used in consumer electronics to connect DVD players, laptops or computers to televisions or monitors.<\/p>\n<p>&nbsp;<\/p>\n<h2>HDMI-Out and HDMI-In<\/h2>\n<p>Even if they look the same, a distinction is made between HDMI input and output. The HDMI output is the port on the device that transmits the content. (e.g. computer, console, etc.)&nbsp;<\/p>\n<p>The HDMI-In port, however, turns the tables: as the name suggests, it is an input, i.e. it is in the device that receives the content. (e.g. screens)&nbsp;<\/p>\n<p>However, there are always HDMI-in ports on computers, such as on our ONE i5. An HDMI-in port on a computer essentially works like an HDMI input on a TV or monitor, with the difference that it can receive content from external devices such as games consoles, Blu-ray players or video cameras.&nbsp;<\/p>\n<p><a href=\"\/produkte\/alle-mini-pcs\/one-i5\" class=\"button\">Discover the ONE i5<\/a><\/p>\n<p>&nbsp;<\/p>\n<h2>What versions does HDMI have?<\/h2>\n<p>In order to keep pace with constantly advancing technology, the HDMI interface has been continuously developed. The various specifications, which amount to a total of 13, have confused many buyers over the years. We also want to keep it short and therefore only go into the most important updates to the interface:<\/p>\n<ul>\n<li>The first HDMI standard 1.0 was published in 2002 and provided a maximum data rate of 4.95 gigabit\/s and a maximum image resolution of 1920 x 1080 pixels.  &nbsp;<\/li>\n<li>It was not until version 1.3 in 2006 that the image resolution was increased to 1560 x 1440 pixels. Furthermore, a new connector type, namely HDMI type C, was introduced to the market with this version.  &nbsp;<\/li>\n<li>The next update came in 2009 with version 1.4, which offers a maximum picture resolution of 3840 x 2160 pixels, i.e. <a href=\"\/blog\/wissen\/was-ist-der-unterschied-zwischen-full-hd-uhd-und-4k\" target=\"_blank\" rel=\"noopener\">4K<\/a>.<\/li>\n<li>The latest version of HDMI is HDMI 2.1b, which came onto the market in 2023 and includes general corrections, clarifications to improve interoperability and the incorporation of errata &#8211; a maximum picture resolution of 8K is now possible.<\/li>\n<\/ul>\n<h2>&nbsp;<\/h2>\n<h2>What do the designations for HDMI cables mean?<\/h2>\n<p>In order to create a clearer and more comprehensible labeling of the cables, they are no longer marked with the version number (1.0, 1.4, etc.), but are divided into four speed classes:<\/p>\n<ul>\n<li><strong>HDMI standard<\/strong>: The transmission rate of up to 2.25 Gbit\/s enables a resolution of 720p or 1080i at 60 Hz. Supports HDMI versions up to 1.3.<\/li>\n<li><strong>HDMI High Speed<\/strong>: Resolution of 2160p at 30 Hz. Supports all versions up to 1.4.<\/li>\n<li><strong>HDMI Premium High Speed<\/strong>: Resolution of 4096p at 60 Hz. Supports versions up to 2.0.<\/li>\n<li><strong>HDMI Ultra High Speed<\/strong>: Resolution of up to 8K@60Hz. Supports all versions up to 2.1.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Advantages of HDMI<\/h2>\n<p>With the help of HDMI, picture and sound can be transmitted via a single cable, making it much easier to connect AV devices. It also means that there is no need for an additional <a href=\"\/blog\/wissen\/was-ist-der-klinkenstecker\" target=\"_blank\" rel=\"noopener\">audio<\/a> connection, which is particularly beneficial for our smallest mini PCs. HDMI also offers excellent quality, can transmit 4K and 3D content and supports surround sound.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Probably the best-known interface in our series on multimedia interfaces goes by the name of HDMI.
