Does DisplayPort Transmit Audio Better Than HDMI?
When comparing audio capabilities, both DisplayPort and HDMI offer high-quality, multi-channel audio, making them both reliable choices.
HDMI: It includes features like ARC (Audio Return Channel) and eARC, which are particularly useful for home theater setups. These features allow you to send audio from your TV back to a sound system without needing additional cables.
DisplayPort: While it doesn’t provide ARC or eARC, it is favored in professional settings. You often see it in multi-monitor setups where audio may not be the primary concern.
Key Features:
-
Audio Quality: Both support up to 8 channels of uncompressed audio.
-
Usage: HDMI is often in home entertainment systems, while DisplayPort thrives in professional environments.
In choosing between them, consider your needs. If your goal is to set up a home theater, HDMI might offer more flexibility with its ARC/eARC capabilities. However, if you are looking into multi-display computer setups, DisplayPort is more common.
📌 Both DisplayPort and HDMI are excellent for transmitting audio, but your decision should focus on what fits your specific use.
