The DP interface and HDMI interface of graphics cards each have their own advantages, and the choice of which one is better depends on the specific usage scenario and requirements. Advantages of DP interface
1. High resolution and high refresh rate support: DP interfaces typically outperform HDMI interfaces in performance, especially when connecting high-resolution and high refresh rate displays. The DP interface can provide higher refresh rates and resolutions, especially in high-resolution settings of 4K and above, the DP interface can provide better display performance.
2. High transmission bandwidth: The transmission bandwidth of DP interface is usually higher than that of HDMI interface, which can support more data volume and faster data transmission, which is particularly important for application scenarios that require processing large amounts of graphics data.
3. Multi screen Expansion Mode: The DP interface supports Multi screen Expansion Mode (MST), which allows multiple displays to be connected through a single port, making it very useful for users who require multitasking or graphic design.
4. Adaptive synchronization technology: The DP interface also supports adaptive synchronization technology (such as G-SYNC or FreeSync), which helps reduce screen tearing and stuttering, and improve the smoothness of games and videos. The advantages of HDMI interface
1. Wide compatibility: HDMI interface is more popular in the market, not only widely used in graphics cards, but also in various devices such as game consoles and TV boxes. The HDMI interface has stronger compatibility and is easier to connect with various devices.
2. Audio and video synchronous transmission: The HDMI interface can simultaneously transmit high-definition video and multi-channel audio signals, simplifying the installation difficulty of system circuits. The HDMI interface also supports various advanced display technologies (such as 3D, HDR, VRR, etc.), improving picture quality and sound experience.
3. Long transmission distance: The length of HDMI cable can reach up to 15 meters, suitable for high-definition video transmission in various scenarios.
4. Rich additional features: The HDMI interface provides a variety of additional features, such as HDCP encryption, CEC consumer electronics device control, and ARC audio backhaul, which are very useful in specific scenarios. Overall consideration
If your main requirement is to connect high-resolution and high refresh rate displays, or to handle large amounts of graphic data, then DP interface may be more suitable for you.
If your device has high compatibility requirements or needs to transmit audio and video signals simultaneously and enjoy multiple additional features, then HDMI interface may be more suitable for you.
There is no absolute 'good' or 'bad', only choices that are more suitable for your usage scenario and needs. When making a choice, one can weigh and choose according to their specific needs.
