Everything You Need to Know About Samsung TV HDMI Ports

Last Updated Mar 31, 2022

HDMI allows the transmission of high-quality audio and video signals between source and display devices. HDMI ports are, therefore, important considerations for when you wish to purchase a television system. You have browsed the market and decided to get a Samsung TV. So will it have HDMI ports? How many of them will it have? What version of the HDMI will you get? Will it be the latest one?

All modern Samsung TVs come with HDMI ports located on the I/O panel. The version of the HDMI standard provided in a Samsung TV may change depending on the model year and the series.

A Samsung TV usually has multiple HDMI ports of different types, and each one is for different situations. So keep on reading to learn when and how you should use each of them.

How Many HDMI Ports On Samsung TV?

In general, every Samsung comes with at least two HDMI ports: a standard port and an HDMI (ARC) port. Some Samsung TVs come with multiple standard HDMI ports. Users can find them on the back of the TV or the One Connect Box.

No matter which Samsung TV you end up with, you will get these HDMI ports. However, the version of the HDMI standard will depend on the TV series you choose. Ensure that the version you get is good enough for the best viewing experience, including picture quality, sound fidelity, etc.

HDMI Cables for Samsung TV

You also don’t need to worry about mismatched HDMI versions between your TV and the source because HDMI standards are fully backward compatible. In this regard, buy an HDMI cable on Amazon supporting a version not too old compared to your TV and the source device.

One important thing to remember is that an overpriced HDMI cable will do you no good compared to one with a reasonable cost. It is a common trick used in the market for HDMI cables.

All HDMI cables in compliance with the same version of the standard have the same capabilities. An HDMI 1.3 cable that costs $100 will not be better than an HDMI 1.3 cable priced at $50. Always buy a medium-tier price HDMI cable so that there are no issues with quality and the product gives you the bang for your buck.

Is HDMI ARC Different Than HDMI?

An HDMI ARC port accepts the same cable as a standard HDMI, but the ARC will transmit audio signals in addition to the video signals carried by a standard HDMI. HDMI ARC eliminates the need to use separate cables for directing audio to specific speakers or soundbars from a TV.

The HDMI ARC (Audio Return Channel) will reduce the amount of cables behind your TV and connected to your home theater or soundbar systems. Using ARC means that audio will go to the same speakers no matter which device you are using as the source. You will be able to control the audio from your TV’s remote directly.

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

Supported Audio Formats

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

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

How to Set Up HDMI (ARC) to Your Samsung TV Or Speaker

Here’s how you can set up an HDMI (ARC) connection between your TV and a speaker:

  • Plug one end of the HDMI cable in the TV’s HDMI IN (ARC) port.
  • Plug the other end in the HDMI OUT port of the speaker.
  • Turn the speakers on to check if they got the audio signal correctly.

If you are using a Samsung home cinema system or soundbar, there will be no need to change the (Anynet+ HDMI-CEC) settings in the TV. Read instructions for setting up an HDMI ARC connection for a non-Samsung home cinema system.

Which HDMI Port Should I Use On My Samsung TV?

Users should connect to the port HDMI IN 1 for 4K/60Hz + HDR playback. The HDMI IN (ARC) port is for audio output to an external speaker or home theater system. The HDMI (HDCP) port is for when it is vital to protect the streaming data.

All HDMI ports with version 2.0 of the standard and above support video streaming at 4K UHD resolutions when used with HDMI cables supporting version 2.0 or higher. 

Tips for Using Other Ports on Your Samsung TV

Here are some tips for when to use some other types of ports seen on Samsung TVs:

  • HDMI (STB) is for connecting with a Set-Top Box. Use this if you prefer to watch cable TV instead of other content available on your smart TV.
  • HDMI (DVI) is for Digital Video Input. DVI is an old standard, and the port is only for if you want to connect an old PC to the TV via HDMI. You will have to use headphones with your PC to receive audio for the content on your TV screen.
  • HDMI (MHL) means HDMI Mobile High-definition Link. It is for streaming content from a mobile device via HDMI to the TV. It is not common because there are wireless options to achieve the same.

What is TV eARC?

The eARC (Enhanced Audio Return Channel) standard allows transmission of even more quality for most audio formats over HDMI cables, compared to HDMI ARC. It is done by preserving the uncompressed audio and sending it expressly through the cable to the output device.

To use eARC, you must have a compatible HDMI cable and the (Anynet+ HDMI-CEC) function enabled on a Samsung smart TV. Follow these steps to enable HDMI-eARC mode:

  • Go to the Sound menu and choose the Expert Settings option.
  • Navigate to the HDMI-eARC Mode option and press Enter on the remote control.

According to Samsung Support, eARC supports compressed 5.1, uncompressed 5.1, uncompressed 7.1-channel and all high-bitrate (up to 192 kHz), 23-bit audio formats available commercially. By contrast, HDMI ARC only supports compressed 5.1-channel audio format for transmission.

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

TV manufacturers usually label the HDMI ports on their TVs. An HDMI port supporting 4K UHD playback will mostly have labels such as 10-bit, UHD and 4K@30Hz or 4K@60Hz, etc. Samsung TVs have the #1 HDMI IN port for 4K playback capability.

If the labels on your TV’s ports are different or absent from the I/O panel, check the manual that you received with the TV. It will have information about which port is best for getting the best possible viewing experience on your TV.

If you are still unsure whether your TV supports 4k streaming via HDMI, check the product specifications on the manufacturer’s website to find out which port it is.


HDMI (High Definition Multimedia Interface) is making the experience of viewing and listening to TV content as close to perfect as it can be. All modern TV systems have HDMI ports of different kinds. 

The newest HDMI 2.1 standard includes support for 8K resolutions at up to 60Hz refresh rate and 4K resolutions up to 120Hz refresh rate. It is pushing the boundaries of what is technically possible even further.

Samsung TVs are some of the best out there, and you are guaranteed to have a good experience of using HDMI to enjoy your favorite content on whichever Samsung TV you buy. Having come here today, you won’t be left unsatisfied when you buy your brand new TV.
