Should I use ARC HDMI?
HDMI ARC is useful for setups that have external speakers for audio, such as soundbars or home theatres. However, if you don’t have any other speakers, and you mainly use your TV’s speakers, HDMI ARC is not really needed. ARC was designed so you can use one remote to control all of your audio devices.
Can I use a regular HDMI cable for ARC?
Any HDMI cable will work universally for HDMI and HDMI ARC/eARC ports. Only a few very outdated HDMI cables could potentially struggle with some of the higher quality audio formats with eARC, but this is unlikely to happen.
Can you use HDMI and optical audio at the same time?
In some cases, if your TV allows you to send two audio signals at the same time, one cable needs to transmit audio while the other will pass on the video signal. So, you can use the optical cable for the audio signal and then insert HDMI, which will transmit video.Mar 20, 2021
How do I know if my HDMI cable is ARC?
Can you use ARC? Check the HDMI connections on the back of your TV, soundbar, or receiver. If the HDMI port has ARC, it should be marked as such. Both your TV and the soundbar or receiver must have ARC for it to work.
