Which HDMI Ports to Use for 4K Samsung TV

Connecting an HDMI port of your Samsung 4K UHD TV with external media for the best 4K experience can be confusing. This blog contains basic information on the HDMI ports and cables and helps you buy the right cable for your 4k Samsung Tv.

HDMI or High Definition Multimedia Interface can transmit compressed video and audio data from an HDMI-compliant source – such as a BluRay player or soundbar, to a compatible screen, in this case, is your Samsung 4K UHD TV.

While these ports have the same function, they are often distinguished for specific purposes to make your home theatre experience more worth the while. This blog tells you which HDMI ports to use for 4k Samsung TV.

What the Labels on Your TV’s HDMI Ports Mean

The HDMI ports behind the TV have almost the same function.

Often you see ports that are color labeled, which usually does not differentiate the ports even grossly. Similar to this is numbered labels like HDMI 1, HDMI 2, HDMI 3, etc.

However, the labels reading as ‘HDMI (STB),’ ‘HDMI (ARC)’, ‘HDMI (DVI), and most importantly ‘HDMI (HDPC)’ etc., signify supporting different external media.

STB designates the connection for the Set Top Box, ARC designates Audio Return Channel, etc. These can be used for the particular external media; however, they do not offer much difference.

However, you need to be mindful of the HDPC label. All other external connections are blocked out while an HDCP connection exists between your 4K TV and any other device. Such connections are called a ‘Handshake’.

Furthermore, sometimes the HMDI ports are labeled with ‘good’,’ better’ or ‘best’. This distinction has no particular significance and is pretty vague.

Not to mention, in case of any confusion, try to solve it with your TV manual. The book, booklet, or pamphlet that comes with your TV when you purchase it and contains product information.

What Does the HDMI Connector Look Like?

An HDMI connector looks almost like a generic USB port. However, it is slightly taller and wider than a USB port.

As the HDMI cables come with two ends, each connection is designed to accept only one end of the cable.

In your Samsung UHD 4K TV, you can find the connectors at the back of the TV. Usually, more than one connector exists in a line in a parallel or horizontal fashion. They might be labeled with a cluster of words like ARC, HDPC, STB, DVI, etc., signifying each specific device for connection with an HDMI wire.

Any device can be connected to these input connectors irrespective of their labeling. However, your TV displays your connectors with these names. The names of these ports can be edited to the desired name that you like.

What Does the HDMI Cable Look Like?

The Cables look like two-ended connectors. One end is connected to the TV port, while the other is connected to the external media device.

The cables range from Type-A, Type-C, and Type-D generally. The distinction is made based on size.

Type-A cable is 14mm and flat. Type C is less flat than Type-A and smaller (mini HDMI). Type D is the smallest and also called a micro HDMI cable.

Other types of cables include Type B cable, the largest HDMI cable. It is also unused for any products. Type E is quite a specialized cable too.

Which HDMI Port to Use For 4k Samsung?
If both your external device and your TV supports 4K HDR content, then you can use an HDMI port irrespective of the label. However, you may want to consider a few things to choose which port to use for your 4K Samsung.

Firstly, you need to ensure that your Samsung 4K can support the same version of HDMI as your external device. For example, if your TV supports HDMI 2.0, your external device such as a BluRay player must also support HDMI 2.0.

Then it’s time to figure out if you are using the HDMI (HDCP) port of your TV to connect a non-HDCP-supported device. In this case, you will not get the true 4K experience.

Moreover, if you want to play audio content with ARC supported HDMI, you should find out if your TV can read surround sound format in ARC as most TVs cannot do so. So, look for a normal HDMI port instead of HDMI (ARC) to play your audio.

One way of checking all of the above points is to read about your 4K Samsung model’s ports in its instruction manual. Besides, you might even discover an unexpected feature about your HDMI connectors.
