Which is better, DP cable or HDMI? 170Hz

Feb 11,2025

When comparing the performance of DP cable (DisplayPort) and HDMI cable (High Definition Multimedia Interface) at a refresh rate of 170Hz, we can analyze from the following aspects: 1. Refresh rate support

DP cable: DP cable supports high refresh rate display, especially in DP versions 1, 4 and above, which can easily support refresh rates of 170Hz or even higher. This is very important for games and professional applications that require high-speed response.

HDMI cable: Although HDMI 2 and 1 versions also support high refresh rates, not all HDMI cables can meet this standard. Traditional HDMI 2, 0, and below versions typically support a maximum refresh rate of 60Hz, which is insufficient for high refresh rate requirements. However, some high-end HDMI 2 and 1 cables can support refresh rates of up to 120Hz or higher, but reaching 170Hz may still be challenging. 2、 Bandwidth and performance

DP line: DP line has higher bandwidth and can transmit more data, thereby supporting higher resolution, refresh rate, and color depth. This enables DP lines to have better performance when displaying high-quality images and videos.

HDMI cable: Although HDMI cable also supports high-definition video and multi-channel audio transmission, its performance may not be as good as DP cable under high bandwidth requirements. Especially when high refresh rate and high resolution are required simultaneously, HDMI cables may encounter bandwidth bottlenecks. 3、 Compatibility and flexibility

DP cable: DP cable usually has better compatibility when connecting computers and monitors, especially on high-end monitors and graphics cards. The DP line also supports multi screen output, allowing multiple displays to be connected on the same line.

HDMI cable: HDMI cable has a wider range of compatibility and can connect almost all types of audio and video devices, such as TVs, projectors, and speakers. However, in the connection between high-end displays and graphics cards, the performance of HDMI cables may not be as good as DP cables. 4、 Conclusion

At a refresh rate of 170Hz, DP cables typically perform better than HDMI cables. DP cables have higher bandwidth and better performance, and can support higher refresh rates and resolutions. DP cables also have better compatibility when connecting high-end displays and graphics cards. However, if the user's device only supports HDMI interface and does not need to achieve extremely high refresh rates (such as 170Hz), then HDMI cable is also a feasible choice.

When choosing a connection cable, users should consider factors such as their device requirements, budget, and compatibility comprehensively. If high refresh rate and high-performance display are required, it is recommended to choose DP cable; If the device only supports HDMI interface or has limited budget, you can also consider using HDMI cable.
