HDMI 2.0a was released on April8, 2015, and added support for High Dynamic Range (HDR) video with static metadata. [120]Most of us use HDMI cables to run dual monitors as they transmit high-quality video and sound. But, what if our PC has got only a single port? Often, we scratch our heads to find a possible solution for this.

HDMI 2.1 cables are up to the task, with an upper limit of 48Gbps (Gigabits per second) rather than 18Gbps. In such cases, you can use the Windows 11 feature that helps in extending your display to multiple devices. This way, you can create a bigger workspace and enjoy quality time playing games or watching videos. Use HDMI Splitter This technology, which is supported by HDMI 2.1but not necessarily by all devices that support HDMI 2.1, drastically increases the maximum bandwidth that HDMI cables can transmitwithout compromising image quality. DSC is only required for very high resolution, high refresh rate devices, and it may be many years before it's needed. Frequently Asked Questions Q: Which devices will support it?

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.

Blu-ray permits secondary audio decoding, whereby the disc content can tell the player to mix multiple audio sources together before final output. [154] Some Blu-ray and HD DVD players can decode all of the audio codecs internally and can output LPCM audio over HDMI. Multichannel LPCM can be transported over an HDMI connection, and as long as the AV receiver implements multichannel LPCM audio over HDMI and implements HDCP, the audio reproduction is equal in resolution to HDMI 1.3 bitstream output. Some low-cost AV receivers, such as the Onkyo TX-SR506, do not allow audio processing over HDMI and are labelled as "HDMI pass through" devices. [155] [156] Virtually all modern AV Receivers now offer HDMI 1.4 inputs and outputs with processing for all of the audio formats offered by Blu-ray Discs and other HD video sources. During 2014 several manufacturers introduced premium AV Receivers that include one, or multiple, HDMI 2.0 inputs along with a HDMI 2.0 output(s). However, not until 2015 did most major manufacturers of AV receivers also support HDCP 2.2 as needed to support certain high quality UHD video sources, such as Blu-ray UHD players. It's important to note that the cables themselves aren't tied to a specific version. There's no such thing as an HDMI 2.0 cable or an HDMI 2.1 cable. Instead, cables are put through a certification process that certifies them for certain maximum bandwidths. HDMI 2.0 generally requires a maximum bandwidth of 18Gbps, and cables that have been certified for that are labeled 'Premium'. The new cables that are certified for HDMI 2.1's maximum bandwidth of 48Gbps arelabeled as 'Ultra High Speed'. This doesn't mean that a 'Premium'cable can't be used with an HDMI 2.1 device, merely that it hasn't been certified for the extra bandwidth. The same goes the other way around, as you can easily use the Ultra High Speed cable on any older HDMI device. Q: Can my existing devices be upgraded? Eric Griffith; Jeremy A. Kaplan (October 22, 2008). "25th Annual Technical Excellence Awards: Home Theater". PC Magazine . Retrieved January 4, 2009. HDMI 2.1 increases the maximum uncompressed bandwidth that an HDMI cable can handle up to 48 Gbps, and the maximum compressed bandwidth to at least 128 Gbps. While this is the maximum bandwidththe cable can handle, it may be some time before devicesneed that much bandwidth, and manufacturers can create TVs that support less bandwidth. For example, if a TV manufacturer only wishes to support 4k @ 120Hz, with 4:2:0 chroma subsampling, then they only need to support about 32 Gbps, and it can still be considered anHDMI 2.1 device. This gives manufacturers significantly more flexibility and allows them to save costs, as they don't need to implement support for the extra bandwidth that the device can't use- a 4k TV doesn't need 8k bandwidth.This also applies to monitors. We only consider a monitor to have HDMI 2.1 ports if those ports support higher bandwidth formats over HDMI. For example, if a monitor supports 4k @ 60Hz with a 10-bit, 4:4:4 signal, it's HDMI 2.1. HDMI 2.1 ports can support different maximum bandwidths, but as long as they support more than the 18Gbps limit of HDMI 2.0, we consider them HDMI 2.1 ports.
