The DP interface is a digital video interface developed by VESA (Video Electronics Standards Association). It was originally designed to replace VGA and DVI interfaces, but now it has become one of the main interfaces for connecting computers and monitors. The DP interface can transmit high-definition video and audio signals, supporting 4K resolution and refresh rates up to 144Hz. In addition, the DP interface also supports multi-screen output, allowing multiple monitors to be connected to the same computer.
The HDMI interface is a digital audio and video interface developed by the HDMI Alliance (HDMI Licensing, LLC). It was originally designed to replace complex ana-log audio and video interfaces, but has now become one of the primary interfaces for connecting TVs, projectors, and other high-definition video devices. The HDMI interface can transmit high-definition video and audio signals, supporting 4K resolution and refresh rates up to 60Hz. In addition, the HDMI interface also supports CEC (Consumer Electronics Control) function, which can control multiple devices through one remote control.
The DP interface uses LVDS (Low Voltage Differential Signaling) technology, which can provide higher bandwidth and faster transmission speed, so it is better at transmitting high-resolution video and audio. The HDMI interface uses TMDS (Transition Minimized Differential Signaling) technology, which can provide better color depth and better audio transmission quality, so it is better at transmitting audio and video.
The DP interface supports multi-screen output and can connect multiple monitors to the same computer. This is useful for users who need to work with multiple screens at once, such as programmers, designers, and investors. The HDMI interface does not support multi-screen output, so only one monitor can be connected to one device.
The DP interface is more powerful in terms of video bandwidth and multi-monitor configurations, supporting higher resolutions and refresh rates. It is typically used for connecting high-resolution monitors or multi-monitor setups. HDMI is widely used in televisions, home theater systems, and consumer electronics equipment, making it more popular and more compatible.
