DisplayPort is the best video transmission standard for any PC. And with USB-C Alt Mode, you can create a DisplayPort connection using a USB cable, getting the best of both worlds. The only downside to HDMI 2.1 144Hz gaming is that you need a compatible TV or monitor and a graphics card or console. HDMI 2.1 graphics cards and the latest game consoles are in high demand, with next-generation consoles and new series of graphics cards from both AMD and Nvidia supporting it natively . High-end GPUs featuring HDMI 2.1 are becoming more and more widely available, with Nvidia RTX 4000 GPUs sporting a single HDMI 2.1 port alongside three DisplayPort 1.4a ports. AMD’s latest RX 7000 GPUs opted instead for three DisplayPort 2.1 ports, as well as a single HDMI 2.1 connector. Abstract: HDMI 1.3c does not add features or performance to HDMI 1.3a. HDMI 1.3c simply adds parameters for testing products based on active HDMI cables. Blu-ray Disc and HD DVD, introduced in 2006, offer high-fidelity audio features that require HDMI for best results. HDMI 1.3 can transport Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master Audio bitstreams in compressed form. [5] :§7 This capability allows for an AV receiver with the necessary decoder to decode the compressed audio stream. The Blu-ray specification does not include video encoded with either deep color or xvYCC; thus, HDMI 1.0 can transfer Blu-ray discs at full video quality. [153] HDMI implements the ANSI/CTA-861 standard, which defines video formats and waveforms, transport of compressed and uncompressed LPCM audio, auxiliary data, and implementations of the VESA EDID. [4] [5] :p. III CEA-861 signals carried by HDMI are electrically compatible with the CEA-861 signals used by the Digital Visual Interface (DVI). No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. [5] :§C The Consumer Electronics Control (CEC) capability allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with one handheld remote control device. [5] :§6.3
Beginning with the seventh generation of video game consoles, most consoles support HDMI. Video game consoles that support HDMI include the Xbox 360 (1.2a), Xbox One (1.4b), Xbox One S (2.0a), Xbox One X (2.0b), PlayStation 3 (1.3a), PlayStation 4 (1.4b), PlayStation 4 Pro (2.0a), Wii U (1.4a), Nintendo Switch (1.4b), Nintendo Switch (OLED model) (2.0a), Xbox Series X and Series S (2.1), and PlayStation 5 (2.1). If you have the right device, the USB-C connection will transmit power as well as video data, allowing you to charge your laptop through the monitor it is connected to. And with Thunderbolt-compatible ports, it is possible to connect two displays at once. High-bandwidth Digital Content Protection (HDCP) is a newer form of digital rights management. Intel created the original technology to make sure that digital content followed the guidelines set by the Digital Content Protection group.
HDMI 1.3b
We'll be sure to keep this document up to date as soon as any HDMI changes are made and will attempt to clarify any questions or issues raised by readers when going through this list. HDMI seems confusing at first, but if handled well by a manufacturer, the differences can be nearly transparent to consumers. The difficulty comes when selecting budget products that may not implement all of the capabilities needed to maximize the potential of HDMI. In these scenarios it's important to not just pay attention to the version of HDMI, but how HDMI is utilized within the product. For example, HDMI "switching" on a receiver implies that no audio is pulled from the HDMI cable, however if the receiver functions as an HDMI "repeater" then users can expect to pull at least multi-channel PCM audio from the connection.
HDMI devices are manufactured to adhere to various versions of the specification, in which each version is given a number or letter, such as 1.0, 1.2, or 1.4b. [5] :p. III Each subsequent version of the specification uses the same kind of cable but increases the bandwidth or capabilities of what can be transmitted over the cable. [5] :p. III A product listed as having an HDMI version does not necessarily mean that it has all features in that version, [90] since some HDMI features are optional, such as deep color and xvYCC (which is branded by Sony as "x.v.Color"). [91] [92] Since the release of HDMI 1.4, the HDMI Licensing Administrator, Inc. (which oversees the HDMI standard) has banned the use of version numbers to identify cables. [93] Non-cable HDMI products, starting on January 1, 2012, may no longer reference the HDMI number, and must state which features of the HDMI specification the product implements. [94] Version 1.0 [ edit ] Audio support: As with HDMI 2.0 and 2.0a, all surround sound formats in use are compatible. HDMI 2.1 also adds eARC, which is an audio return channel upgrade that provides enhanced audio connection capability for immersive surround sound formats between compatible TVs, home theater receivers, and soundbars. eARC is compatible with Dolby Digital Plus, Dolby TrueHD, Dolby Atmos, DTS-HD High-Resolution Audio/DTS HD Master Audio, and DTS:X. As of January2021 [update], nearly 10 billion HDMI devices had been sold. [9] Specifications [ edit ]The HDMI royalty is only payable on licensed products that will be sold on a stand-alone basis (i.e., that are not incorporated into another licensed product that is subject to an HDMI royalty). For example, if a cable or IC is sold to an adopter who then includes it in a television subject to a royalty, then the cable or IC maker would not pay a royalty, and the television manufacturer would pay the royalty on the final product. If the cable is sold directly to consumers, then the cable would be subject to a royalty. [89] Versions [ edit ]
HDMI Ethernet channel: Adds internet and home network connectivity to HDMI. In other words, both Ethernet and HDMI functions are available within a single cable connection. MHz was the maximum TMDS character rate allowed in version 1.2a of the HDMI Specification and earlier. In version 1.3, the maximum allowed speed was increased to 340 MHz, and in version 2.0 it was increased to 600 MHz. These are only the maximum speeds permitted by the specification; individual devices may be limited to any speed within the maximum allowed. the problem with that list thou...if you look at pretty much any regular high speed hdmi, they all are capable of 4k60hz......hell standard hdmi do they even sell them anymore? and yea ultra is a scam lolOn September18, 2014, Nvidia launched GeForce GTX 980 and GTX 970 (with GM204 chip) with HDMI 2.0 support. On January22, 2015, GeForce GTX 960 (with GM206 chip) launched with HDMI 2.0 support. On March 17, 2015, GeForce GTX TITAN X (GM200) launched with HDMI 2.0 support. On June 1, 2015, GeForce GTX 980 Ti (with GM200 chip) launched with HDMI 2.0 support. On August 20, 2015, GeForce GTX 950 (with GM206 chip) launched with HDMI 2.0 support. Enabled 3D 1080p video at 120 Hz so that each eye can receive full HD (1080p 60Hz—or 120 Hz total) per Eye The HDMI standard was not designed to pass closed caption data (for example, subtitles) to the television for decoding. [42] As such, any closed caption stream must be decoded and included as an image in the video stream(s) prior to transmission over an HDMI cable to appear on the DTV. This limits the caption style (even for digital captions) to only that decoded at the source prior to HDMI transmission. This also prevents closed captions when transmission over HDMI is required for upconversion. For example, a DVD player that sends an upscaled 720p/1080i format via HDMI to an HDTV has no way to pass Closed Captioning data so that the HDTV can decode it, as there is no line 21 VBI in that format.
The HDMI founders were Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, and Toshiba. [1] Digital Content Protection, LLC provides HDCP (which was developed by Intel) for HDMI. [10] HDMI has the support of motion picture producers Fox, Universal, Warner Bros. and Disney, along with system operators DirecTV, EchoStar ( Dish Network) and CableLabs. [3] LPCM, Dolby Digital, DTS, DVD-Audio, Dolby Digital Plus, Dolby TrueHD, DTS-HD High Resolution Audio, DTS-HD Master Audio, MPCM, DSD, DST, Dolby Atmos, DTS:XHDMI 2.0b was released March 2016. [121] HDMI 2.0b initially supported the same HDR10 standard as HDMI 2.0a as specified in the CTA-861.3 specification. [118] In December 2016 additional support for HDR Video transport was added to HDMI 2.0b in the CTA-861-G specification, which extends the static metadata signaling to include hybrid log–gamma (HLG). [118] [122] [123] Version 2.1 [ edit ] Practical Issues and Tips: There is no consumer-focused practical difference between HDMI v1.3a and v1.3b1. HDMI 1.3c Some of the transmitted bits are used for encoding purposes rather than representing data, so the rate at which video data can be transmitted across the HDMI interface is only a portion of the total bit rate. The Blu-ray Disc Association (BDA) spokespersons have stated (Sept. 2014 at IFA show in Berlin, Germany) that the Blu-ray, Ultra HD players, and 4K discs are expected to be available starting in the second half to 2015. It is anticipated that such Blu-ray UHD players will be required to include a HDMI 2.0 output that supports HDCP 2.2.
