HDMI Micro Connector – A new, smaller connector for phones and other portable devices, supporting video resolutions up to 1080p.

For the ultimate HDMI 144Hz gaming experience, however, you want the latest generation of HDMI connectors . HDMI 2.1 144Hz options include every one of the most popular gaming resolutions, from 1080p, all the way to 4K – no compression required. If you don’t mind using compression, you can even push it to 240Hz on compatible monitors.

HDMI 1.4b

Audio return channel: Audio return channel (HDMI-ARC) provides a single HDMI connection between a TV and a home theater receiver. It passes audio/video signals from the receiver to the TV and also passes audio originating from the TV's tuner to the receiver. In other words, when listening to audio accessed by the TV's tuner, you don't need a separate audio connection going from the TV to the home theater receiver. Hopefully this article helps you understand the format differences and aids in your ability to discern what features are important to you as you shop for HDMI-equipped products. HDMI 1.0 If you want to run 1080p 144 Hz, you only need a High Speed HDMI cable, which is basically any HDMI cable. The cable is not really the determining factor here. If you want to run 1080p 144 Hz over HDMI, you will need a monitor that supports this, which is rare. Does HDMI support 144Hz? Absolutely, but depending on the generation of cable and port you’re working with, you may only have access to some resolutions, rather than all of the most popular ones. All versions of HDMI from HDMI 1.3 onward right through to HDMI 2.1 provide enough raw bandwidth for 144Hz, provided sacrifices are made in color, chroma, compression, or resolution. HDMI 2.1 – the latest and greatest HDMI version – has the most support for 144Hz with the least compromise, allowing 1440p and 4K resolution at 144Hz; although anything higher than that and you’ll need to use Display Stream Compression (DSC) or Chroma Subsampling. Here, we still use OBS for testing, the test hardware is Raspberry Pi 4B, and the test system is 2022-04-04-raspios-bullseye-armhf-full.

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 1.3a

Uncompressed 8 bpc (24 bit/px) color depth and RGB or Y′C BC R 4:4:4 color format are assumed on this table except where noted. On January 28, 2008, In-Stat reported that shipments of HDMI were expected to exceed those of DVI in 2008, driven primarily by the consumer electronics market. [21] [31] The royalty fee structure is the same for all volumes. The following variable per-unit royalty is device-based and not dependent on number of ports, chips or connectors:

Abstract: HDMI 1.3b does not add anything over 1.3a. It simply adds parameters for testing products. Uncompressed 10 bpc color depth and RGB or Y′C BC R 4:4:4 color format are assumed on this table except where noted. The first version of the HDMI spec arrived in December 2002. It primarily used a similar architecture as DVI for sending video signals but sent audio and other data during a video stream's blanking intervals. It offered a data transfer rate of 4.9Gbps to deliver 720p resolution at 120Hz, 1080p at 60Hz, and 1440p at 30Hz. The standard also supported 8-channel audio. HDMI 1.1

On September1, 2020, Nvidia launched the GeForce RTX 30 series, the world's first discrete graphics cards with support for the full 48 Gbit/s bandwidth with Display Stream Compression 1.2 of HDMI 2.1. [185] [186] [187] Gaming consoles [ edit ] In September 2009, AMD announced the ATI Radeon HD 5000 series video cards, which have HDMI 1.3 output (deep color, xvYCC wide gamut capability and high bit rate audio), 8-channel LPCM over HDMI, and an integrated HD audio controller with a Protected Audio Path that allows bitstream output over HDMI for AAC, Dolby AC-3, Dolby TrueHD and DTS-HD Master Audio formats. [176] [177] [178] The ATI Radeon HD 5870 released in September 2009 is the first video card that allows bitstream output over HDMI for Dolby TrueHD and DTS-HD Master Audio. [178] The AMD Radeon HD 6000 Series implements HDMI 1.4a. The AMD Radeon HD 7000 Series implements HDMI 1.4b. [179] Added DSD (Direct Stream Digital) support, allowing native transmission of Super Audio CD (SACD) content at up to 8 channels Legacy interfaces such as VGA, DVI and LVDS have not kept pace, and newer standards such as DisplayPort and HDMI clearly provide the best connectivity options moving forward. In our opinion, DisplayPort 1.2 is the future interface for PC monitors, along with HDMI 1.4a for TV connectivity. The annual fee is due upon the execution of the Adopter Agreement, and must be paid on the anniversary of this date each year thereafter.

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.Practical Issues and tips: HDMI 1.3 is a requirement for Deep Color support or use of the new xvYCC expanded color space. If high definition audio is important to you, you still may not need v1.3 if your player can decode the native HD audio formats into uncompressed PCM audio. This uncompressed audio, up to 8 channels, can be sent over HDMI 1.0.Typically, 24p support coincides with v1.3, however this is nothing more than coincidence of when both format and spec came into popularity. HDMI 1.3a The highest refresh rate currently supported by any games console is 120Hz. The PlayStation 4 supports a maximum of 60Hz. The Xbox Series X and PS5 both offer 4K@120Hz gaming support with compatible displays over HDMI 2.1. Not all games will run at that kind of frame rate, however, so support is different from game to game. 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. TMDS encoding uses 10 bits of the transmission to send 8 bits of data, so only 80% of the transmission bit rate is available for data throughput. 16b/18b encoding uses 18 bits of bandwidth to send 16 bits of data, so 88. 8% of the transmission bit rate is available for data throughput. This was a big leap for the standard when it launched in June 2006. First of all, it finally doubled the bandwidth to 10.2Gbps, which bumped up the ability to deliver 720p resolution at 240Hz, 1080p at 120Hz, and 1440p 60Hz. Additionally, it also added support for 4K or 2160p at 30Hz, although it wasn’t made official until the release of HDMI 1.4. It also added support for 10-bit, 12-bit, and even 16-bit color depth, depending on the resolution. This version also had support for increased color spaces and optional support for Dolby TrueHD and DTS-HD Master Audio. HDMI 1.3 also introduced a new Type-C Mini HDMI connector (more on that later). Like 1.2, this one also saw a mid-cycle update with version 1.3a, which again had similar CEC updates and some modifications to the smaller type-c connector. HDMI 1.4, 1.4a, and 1.4b
