In general, every Samsung comes with at least two HDMI ports: one normal and one ARC. Some Samsung televisions provide numerous standard HDMI connectors.

They’re located on the back of the television or the One Connect Box.

An HDMI cable transfers data from your device to your smart Tv.

You also don’t have to be concerned about different HDMI models, whether they are suitable for your TV and the source, because HDMI standards are fully backward compatible.

In this regard, choose an HDMI cable from Amazon that supports a version that is not too outdated compared to your TV and the source device.

One thing to keep in mind is that a pricey HDMI cable will do you no good compared to one that’s reasonably priced. It’s a frequent ploy in the HDMI cable market.

If an HDMI cable is compliant with a specific version of the standard, then all devices connected to it will share the same capabilities. A $100 HDMI 1.3 cable won’t perform better than a $50 HDMI 1.3 cable. Always buy a mid-tier HDMI cable to avoid quality issues and to get the most bang for your buck.

Is HDMI ARC Distinct From HDMI?

An HDMI ARC connector accepts the same connection as a conventional HDMI port, but the ARC will transmit audio signals in addition to video signals. HDMI ARC eliminates the need for separate cables to route audio from a TV to specified speakers or soundbars.

The HDMI ARC (Audio Return Channel) will reduce the number of cords connected to your home theatre or soundbar systems behind your TV. Using ARC implies that audio will be sent to the same speakers regardless of the source device. Now you can easily control the sound from your TV’s remote.

If you don’t use external speakers, HDMI ARC is useless, but you can still use it as an ordinary HDMI connection. If you want to connect an external ARC-compatible speaker to the TV, you’ll need an HDMI cable that supports version 1.4 or higher.

Audio Formats Supported

The following audio formats are supported by HDMI (ARC) ports on Samsung TVs:

  • Dolby Digital Surround (up to 5.1 channels)
  • Digital Surround DTS (up to 5.1 channels and only available on pre-2018 TVs)
  • PCM (2-channel) (2-channel)

How to Connect HDMI (ARC) to a Samsung TV or Speaker

Below are the steps to link your TV to a speaker utilizing an HDMI (ARC) connection:

  • Connect one end of the HDMI cable to the TV’s HDMI IN (ARC) connector.
  • Now link the other end of the cable to the speaker’s HDMI OUT port.
  • Turn on the speakers to see if they received the audio stream correctly.
  • There is no need to adjust the (Anynet+ HDMI-CEC) settings in the TV if you are using a Samsung home cinema system or soundbar. 

Which HDMI Port Should Be Utilized On My Samsung TV?

For 4K/60Hz + HDR playback, users should connect to HDMI IN 1. The HDMI IN (ARC) connector is used to connect to an external speaker or home theatre system to output audio.

When it’s critical to safeguard the streaming data, the HDMI (HDCP) port is used.

When used with HDMI cables that support version 2.0 or higher, all HDMI ports with version 2.0 or higher offer video streaming at 4K UHD resolutions.

Other Ports on Your Samsung TV: How to Use Them

Here are some pointers on when to use some of the other types of connectors found on Samsung TVs:

  • HDMI (STB) is used to connect to a Set-Top Box. Use this if you prefer to watch cable TV over other material on your smart TV.
  • HDMI (DVI) is an abbreviation for Digital Video Input. DVI is an outdated technology, and the connector is only for connecting an old PC to the TV through HDMI. To hear the audio for the content on your TV screen, you must utilize headphones with your PC.
  • HDMI (MHL) is an abbreviation for HDMI Mobile High-definition Link. It’s used to transmit material from a mobile device to a television through HDMI. It is uncommon because there are wireless solutions for accomplishing the same thing.

What Exactly is TV eARC?

In comparison to HDMI ARC, the eARC (Enhanced Audio Return Channel) standard enables even higher-quality audio transmission over HDMI connections. It is accomplished by preserving the uncompressed audio and transmitting it directly to the output device via the cable.

You must have a suitable HDMI cable, and the (Anynet+ HDMI-CEC) capability enabled on a Samsung smart TV to use eARC. In order to activate HDMI-eARC mode, do the following:

  • Select the Expert Settings option from the Sound menu.
  • Navigate to the HDMI-eARC Mode option on the remote control and hit Enter.

Compressed 5.1, uncompressed 5.1, uncompressed 7.1-channel, and all commercially available high-bitrate (up to 192 kHz) 23-bit audio codecs are all supported by eARC, according to Samsung Support. On the other hand, HDMI ARC can only transmit compressed 5.1-channel audio formats.

How Do I Determine If My HDMI Port Is 4K?

HDMI ports on televisions are often labeled by the manufacturer. An HDMI connection that supports 4K UHD playback will typically feature labels such as 10-bit, UHD, and [email protected] or [email protected], among others. The most HDMI IN connections for 4K playback is found on Samsung TVs.

If the labels on your TV’s ports differ or are missing from the I/O panel, consult the handbook that came with the TV. It will include information on which port is optimal for getting the optimum viewing experience on your television.

If you’re still not sure whether your TV supports 4k streaming over HDMI, look at the product details on the manufacturer’s website to see which port it has.
