No new HDMI cable is required to use HDMI ARC. Any HDMI cable should be able to meet the requirements – only when we switch to eARC could this (potentially) become a problem. But we`ll come back to that later. HDMI 2.1 is the latest version of the HDMI specification – the technical list of requirements that any manufacturer wishing to implement HDMI 2.1 on their devices must meet. And yes, HDMI eARC is one of the many features of HDMI 2.1. But that`s where it gets weird. However, if you`re buying a small TV for a kitchen or bedroom and have no intention of plugging it into a soundbar or external receiver, you can probably stick with HDMI ARC (or not even HDMI ARC). And if you`re buying a cheap soundbar to enhance your TV`s sound and you`re not interested in Dolby Atmos, high-resolution audio, or durability, this device is probably suitable even without ARC or eARC. There are a few things that are most important when it comes to choosing an HDMI cable. It`s a relatively inexpensive purchase, but what you need to consider is the TV resolution, cable length, and HDMI types (standard, mini, mic).
Again, pay attention to the ARC label on the HDMI port that connects to the TV. In the first option below, you would connect all your sources to the soundbar and simply use the TV cable. Don`t worry if your TV is compatible with eARC, but your soundbar or amplifier is only compatible with ARC. You can still listen to audio through your audio system. However, due to bandwidth limitations, you cannot benefit from maximum high bitrate audio playback from the source. Step 2.Press and hold the Volume Up (+) and Volume Down (-) buttons on the remote control for more than 5 seconds until INIT appears. Step 5. A TV arc notification is displayed on the front screen, and then the TV sound is played. Second, you can establish these connections through the soundbar itself, allowing you to move the multiple HDMI ports from the TV to the soundbar without the need for additional setup.
This is especially useful in cases where your TV is wall-mounted and you don`t have access to all HDMI ports or just want a cleaner look with fewer cables to and from the TV. This also means that fewer cables need to be installed. Any HDMI connection can now be called HDMI 2.1, and that`s not correct. ARC stands for Audio Return Channel, where supported devices can use a traditional HDMI connection to provide and receive audio channels alongside video, rather than relying on a separate dedicated optical digital audio connection. HDMI ARC, on the other hand, not only cleans up your cable management — you only need an HDMI cable from the back of your TV — but also provides greater bandwidth for gaming. Admittedly, the standard HDMI ARC is still limited in its output, with a maximum of 5.1 compressed audio channels that can be streamed from TV to soundbar, or a highly compressed version of Dolby Atmos instead of the real deal, but it comes with other advantages. The enhanced audio feedback channel (also known as eARC) is the next generation of ARC. This is a feature implemented in the latest HDMI 2.1 specification.
While Dolby Atmos can now be streamed over regular ARC (via Dolby Digital Plus), eARC offers improved bandwidth for higher quality Dolby TrueHD and DTS-HD Master Audio streams, including Dolby Atmos. For people who connect their devices to an AV receiver (or soundbar with at least one HDMI input), the need for eARC is slightly lower. Typical high-quality audio sources (mainly Blu-ray players) can be connected directly to this device without relying on the TV`s audio capabilities. But there`s always a chance you`ve connected a high-end audio source to your TV, and at those times, eARC would come in handy. Not all TVs currently use HDMI 2.1 for all HDMI ports, but a significant number offer partial 2.1 support for some features, with eARC being the most commonly offered. You`ll find eARC on models from LG, Samsung, Sony, TCL, Vizio and Hisense – and just about every model on our list of the best TVs we`ve tested. (Best of all, we have a separate list of the best TVs with HDMI 2.1 that allows you to limit your purchases to models that offer the new standard.) If you connect the HDMI ARC cable to the soundbar and all the settings are correct but it doesn`t work, you can also reset the soundbar device by following the steps below. Most Samsung TVs support HDMI Audio Return Channel. HDMI ARC is designed to reduce the number of cables between your TV and an external home theater system or soundbar. The audio signal can travel to and from the speakers in both directions, improving sound quality and signal latency. Current soundbars such as LG`s 2022 Dolby Atmos SQ series, award-winning Sonos Arc and Samsung`s QA series will include eARC-enabled HDMI 2.1 outputs.
Higher bandwidth translates into more data that can be transmitted (a larger pipe). Higher bandwidth also means that the digital audio signal does not need to be compressed and is much more detailed, rich and vivid. Therefore, with an eARC channel, you can enjoy the depth of cinematic surround sound through formats such as DTS:X and DOLBY ATMOS. Due to the limitations of the standard CRA, only eARC can currently handle these formats. In this configuration, your receiver/soundbar is the central hub of the entertainment system. You switch between your sources and adjust the volume using the remote control of your receiver/soundbar. You only use your TV`s remote control to turn on the TV and access all the apps built into the TV. However, ARC may allow you to receive Dolby Atmos audio from streaming services such as Netflix, Disney Plus, and Amazon Prime Video because these services integrate Dolby Atmos into the lossy Dolby Digital Plus format that ARC can handle.
But it also has the same limitations as the S/PDIF standard it replaces. Namely, it cannot stream HD or high-bitrate audio, which is used by standards such as Dolby Atmos and DTS:X. This is particularly irritating because downstream audio over HDMI can easily transmit the signal. This is a pure limitation of the ARC specification. This setup allows you to use your TV`s remote to switch between the Blu-ray player and game console sources, and in most cases, you can use your TV`s remote to control the volume. HDMI ARC requires a TV with HDMI ARC port and soundbar, AV receiver or other audio device with a suitable HDMI ARC port. You`ll also need an HDMI cable to connect these two devices – virtually any HDMI cable gets the job done, as HDMI ARC isn`t particularly demanding when it comes to bandwidth. LG was the first manufacturer to use the new standard, producing the first 4K TVs with HDMI 2.1 ports in 2019. All 2022 LG OLED TVs have up to four HDMI 2.1 ports, with Samsung offering one on most models and four on its flagship packages. Meanwhile, many Pansonic and Sony 2022 lines also have a mix of connectors. Step 1.Press the HOME button on your Samsung remote and then select Settings To use the new features, both devices must be eARC compatible. Fortunately, eARC is available in many more equipment than high-end 8K TVs.
Compatible devices include the Sonos Beam, Yamaha RX-V6A, and Sony X950 from 2019. The format is backwards compatible with ARC, but don`t expect to stream Atmos via an older TV. While most new TVs don`t require the other features of HDMI 2.1, manufacturers can implement the most useful parts of HDMI 2.1, such as eARC. IMPORTANT: This article applies only to certain products and/or operating systems. Review the Applicable Products and Categories section of this article before you begin these steps. An optical audio cable (TOSLINK) has a function: transmit audio from your TV, for example, to a receiver or directly to a speaker. It is good, clean and can transmit multiple audio channels to your device. Some soundbars, such as the Vizio Elevate, offer Dolby Atmos sound via eARC, as well as a second (or in some cases, a third) HDMI input There`s one important thing to keep in mind: while newer HDMI devices are designed to be backwards compatible with older HDMI devices, that`s not always true for eARC.
For example, if you connect an eARC TV to an ARC soundbar, you`ll still get the sound from the TV – you`re limited to ARC`s lower quality audio capabilities, but it should work. However, the eARC specification does not require eARC devices to be backwards compatible, so there may be instances where this does not work at all.
