Which characteristics are true about the DisplayPort interface?

Only sends video signals
Uses lower voltage than DVI or HDMI
Can send audio signals only
Does not support multi-channel audio

The correct answer is: Uses lower voltage than DVI or HDMI

The DisplayPort interface is designed with versatility in mind and offers a range of features that enhance video and audio transmission. One of the key characteristics of DisplayPort is that it operates at a lower voltage compared to both DVI and HDMI. This is significant because lower voltage usage can lead to reduced power consumption and heat generation, making it an efficient choice for modern display technologies. DisplayPort is also capable of transmitting both video and audio signals simultaneously, which highlights its multifunctionality. The interface supports high-definition video and multi-channel audio formats, providing a comprehensive solution for transporting high-quality media. Additionally, DisplayPort has the ability to daisy chain multiple monitors from a single output, maximizing workspace without compromising performance. While the other options touch on aspects of audio and video transmission, they do not accurately describe the capabilities of DisplayPort. Therefore, the characteristic of using lower voltage than DVI or HDMI emphasizes the efficiency of this interface compared to its counterparts.
