DP cable and HDMI cable: the difference and how to choose the cable that suits you better
2024-11-04 17:30:54
What is DP?
DisplayPort (DP) is a digital display interface standard developed by the Video Electronics Standards Association (VESA). The DP interface is mainly used to connect computers to monitors, but is also widely used in other devices such as TVs and projectors. DP supports high resolution and high refresh rate, and can transmit audio and data signals at the same time.
What is HDMI?
HDMI (High-Definition Multimedia Interface) is an interface standard designed for audio and video transmission, jointly developed by multiple companies. HDMI is widely used in consumer electronic products such as TVs, Blu-ray players, game consoles, and computers. HDMI not only supports video transmission, but also transmits high-quality audio signals.
The difference between DP and HDMI:
1. Connector shape
The connector of the DP cable is asymmetrical, with a 20-pin design and a physical latch system to ensure a stable connection. The connector of the HDMI cable is symmetrical, contains 19 pins, and relies on friction to maintain the connection without latching.
2. Bandwidth and resolution support
DP cables can support higher resolutions and refresh rates with higher bandwidth. For example, the bandwidth of the DP 2.1 version is as high as 80Gbps, which is enough to meet the needs of 10K and 16K resolutions. In the latest HDMI 2.1 version, the bandwidth of the HDMI cable has also been increased to 48Gbps, supporting 8K resolution and 120Hz refresh rate.
3. Technical details
The DP interface supports more video specifications. For example, in the DP 1.4 version, it supports 4K 240Hz and 8K 60Hz video output, while HDMI 2.1 supports 2K 240Hz, 4K 144Hz, 5K 60Hz, and 8K 60Hz. In addition, the DP interface also supports AMD's multi-screen splicing technology, which is an important advantage for professional users who need multiple monitors.
4. Cost
DP is completely free to use, while the HDMI interface charges a certain copyright fee and pays a certain fee to the HDMI Association every year.
5. Popularity
In terms of popularity, it can be said that the HDMI interface is better. In daily life, HDMI interfaces are obviously more common than DP interfaces, and are widely used in consumer electronic products such as home theaters, game consoles, and TVs. DP cables appear more in professional fields, such as gaming PCs, high-end monitors, etc., providing users with a higher quality video experience.
In actual applications, which interface to choose depends on the specific usage scenario and personal needs. If you need higher resolution and refresh rate, or multi-monitor configuration, the DP interface may be a better choice. If you are mainly concerned about the home entertainment experience, or want to obtain a wider range of device compatibility, the HDMI interface may be more suitable for you.
