When your computer has both HDMI and DP interfaces, which interface to connect depends on your specific needs and usage scenarios.
HDMI interface is a digital audio and video interface, which is mainly used to transmit high-definition audio and video signals. With its high-quality audio and video transmission capability, simplified connection mode and wide compatibility, it has become one of the most commonly used interfaces in modern homes and entertainment equipment. The HDMI interface supports a variety of audio and video formats and signal types, including high-definition video, multi-channel audio, 3D content, etc., and is suitable for connecting multimedia devices such as TVs, monitors, projectors, etc.
The DP interface (DisplayPort) is a digital video interface standard developed by the PC and chip manufacturers alliance and standardized by the Video Electronics Standards Association (VESA). It is mainly used for the connection between video source and display and other devices, and supports carrying audio, USB and other forms of data. DP interface has greater advantages in higher resolution and refresh rate, and can support higher resolution and refresh rate, including 4K, 5K, 8K or even higher. In addition, DP interface also supports multi stream transmission technology, which can simultaneously transmit multiple video streams through a single interface, which is particularly convenient in multi display settings.
Therefore, if you prefer the quality and compatibility of stressed video transmission and the convenience of connecting multimedia devices, HDMI interface may be a better choice. If you need higher resolution and refresh rate support, or are using multi display settings, the DP interface may be more suitable for your needs.
In general, HDMI and DP interfaces have their own advantages. Which interface to choose depends on your specific needs. If you are not sure which interface to choose, it is recommended to refer to the specifications and requirements of your display or other output devices, or consult professional technical support personnel.
