HDMI 1.2 – This version adds the ability to pass SACD signals through. These are signals from a Super Audio CD from, for example, a DVD player to a receiver, both with HDMI. HDMI 1.1 – This version adds the ability to feed not only video and 2 channel audio through a single cable, but also the ability to feed surround sound such as Dolby Digital and DTS, up to 8 channels (7.1 setting) HDMI 1.0 – HDMI 1.0 combines a digital video signal with a 2 channel audio signal in a single cable. This could be, for example, between a DVD player with HDMI and a TV with HDMI. HDMI has expanded considerably in recent years, which has resulted in different versions of this connection. All the newer versions of HDMI are compatible with older versions installed on older equipment, but you will not be able to use the latest functions of the new HDMI version. Below you can find an overview.HDMI also has a type of illegal copy protection called HDCP. HDMI can be integrated into TVs, receivers, DVD players, Blu-ray players, digital decorders and more. Today this is often the case.HDMI can pass high video resolutions depending on the source material and source.Generally, 4K UHD signals require a faster HDMI cable than what 1080P HD signals require, and 8K UHD signals requires even more faster HDMI cables.HDMI stands for High Definition Multimedia Interface. In the past, or with older connections, the digital signal from a certain source (DVD player, VCR, etc.) had to be converted to analog so that it would reach the TV, resulting in a loss of quality of the signal, in other words, the loss of data. Today we have HDMI for this. HDMI can feed a signal digitally from a source to the TV (or receiver), without loss of quality. Honestly it depends on the capability (i.e. In the market, to make it easier to understand, some cables are simply advertised as " HDMI v1.4 cable", " HDMI 2.0 cable" or " HDMI 2.1 cables", these names are not that scientific, but they are practical and pretty easy to remember.ĭo I Need a Special HDMI Cable For The New TV? This cable type is optimized for HDMI version 2.1. It supports up to 48Gbps bandwidth and is less susceptible to EMI (electromagnetic interference) caused by some wireless devices. Ultra High-Speed HDMI Cable: This cable type includes all of the capabilities of the other cables with added support for 8K video with HDR and even 10k resolution. Cable bandwidth support is 18Gbps and is optimized for HDMI versions 2.0/a/b. Premium High-Speed HDMI Cable: This cable type is designed for reliable transfer of 4K/UltraHD resolution video, including 4K/60 Hz, HDR, and expanded color range. It is optimized for HDMI versions 1.3 to 1.4a. Bandwidth transfer speeds up to 10 Gbps are supported. High-Speed HDMI Cable: This type of cable is designed to handle video resolutions of 1080p and 4K (30 Hz) as well as provide support for 3D and Deep Color. It is optimized for HDMI versions 1.0 to 1.2a. Standard HDMI Cable: With bandwidth capacity of up to 5 Gbps. Refresh rate, resolution and color depth are three major factors of the bandwidth definition, to make it simply, Bandwidth can be roughly estimated as Resolution * Refresh * Color Depth, this is not exactly accurate, but it gives you a rough image of bandwidth. HDR (High Dynamic Range) technology built into 4K TVs and Blu-ray High-speed HDMI cables are also necessary for taking advantage of the HDTV, but game players may prefer higher refreshing rate for a smoother For example, 60Hz is an adequate refresh rate for 4K High resolution and refresh rate devices require better rated cables.įaster HDMI cables allow for higher refresh rates at different Even though HDMI cables do not have versions in theory, but their bandwidth capability does really matter when actually using HDMI cables. HDMI supports high-resolution video and multi-channel audio through a single-cable (HDMI Cable) connection. HDMI is a pure digital protocol which can feed signals digitally from a source to the TV (or other digital receiver), without loss of quality. In the past, digital signals from a certain source (DVD player, VCR, etc.) had to be converted to analog to be displayed on TV, resulting in a loss of signal quality. HDMI stands for High Definition Multimedia Interface.
