What is the difference between HDMI and HDMI-ARC on Samsung TVs?
The main difference between HDMI and HDMI-ARC on Samsung TVs is the ability to send audio signals from the TV back to an external device, such as a soundbar or home theater system. HDMI-ARC (Audio Return Channel) allows for this two-way communication, while standard HDMI only sends video and audio signals from the external device to the TV.
This means that if you want to use an external audio system with your Samsung TV, you’ll need to use an HDMI-ARC port to connect it. This will allow you to send audio signals from the TV to the external device, and also receive audio signals from the external device back to the TV. This can be useful for features like voice control or audio feedback.
Do I need to use HDMI-ARC to connect my soundbar to my Samsung TV?
If you want to connect your soundbar to your Samsung TV and use it as the primary audio output, then yes, you should use an HDMI-ARC port. This will allow you to send audio signals from the TV to the soundbar, and also receive audio signals from the soundbar back to the TV.
However, if you’re using a separate audio source, such as a Blu-ray player or game console, and you’re only using the soundbar for that specific device, then you can use a standard HDMI port. In this case, the audio signals will only be sent from the external device to the soundbar, and not from the TV.
