What is the HDMI (ARC) port on TV used for?

HDMI is now the most popular and quality connection standard when connecting between laptop devices, phones to TVs or transmitters. On most TVs today, HDMI ports are available for convenient data conversion. However, some TVs have an ARC symbol at the HDMI connector. So, what does ARC mean and what is the case?

1. What is HDMI - ARC port?

For a TV with a regular HDMI port (without additional ARC symbols), this port is an IN port, ie the port RECEIVING image and audio signals from other devices (player, laptop, staging. .). This also means, this HDMI port only receives but not output sound to the speaker, staging machine . okay, if you want to export you must use another connection (Optical, Audio Out .).

However, if your home TV has an HDMI port (ARC), things are much simpler, because this port can output audio back to the speakers, amplifiers, staging machines . with an HDMI cable connection.

If you connect a TV with HDMI (ARC) to a sound system, you can both receive image signals from the player on the TV, and you can also output sound to the speakers with just one connected cable.

2. Connect the TV to the speaker via HDMI - ARC port:

For families who need to constantly connect the TV to speakers, amplifiers and sound systems to enjoy the more vivid sound, the HDMI - ARC port will take care of that.

However, to be able to connect, the devices need to have the following conditions:

1. Television with HDMI (ARC) port.
2. On the chassis, amplifier, speakers with HDMI OUT ports that support ARC (not all HDMI OUT ports have ARC, you need to understand the information before buying or see the device's user guide mentioned This connection standard is not).
3. HDMI cable.

To be able to connect the port on the TV to audio devices, follow the instructions below:

One HDMI cable plugs into the HDMI (ARC) port on the TV, the other end plugs into an HDMI OUT port (with ARC) on the audio device. On the television, press the INPUT, SOUNCE button or the arrow button with the arrow icon . to select the data input of the TV to be the HDMI port you plugged in.

Note:

1. To be sure, before purchasing the system, amplifiers, speakers . you should check carefully whether this product is sure to support ARC.
2. If you have followed the steps that are still not audible, it may be because your HDMI cable is too old or of poor quality, you can buy a new HDMI cable.
