Both DP and HDMI are high-definition digital interfaces that can transmit video and audio signals. In 4K and below displays, DP and HDIMI are not very different. DP supports 8K display.
HDMI is more widely used than DP. Most televisions, projectors, monitors, etc. support HDMI interface, and independent graphics cards generally also support HDMI interface;
DP interface can be understood as an enhanced version of HDMI, which is more powerful in audio and video transmission. If your display is at 3840 * 2160 resolution or 7680 * 4320, that is, 8K, you can support it with DP cable 4K@60HZ , optical fiber DP line can reach 8K@60hz At present, the DP1.4 version can reach 8K, while HDMI must be supported until the 2.1 version. At present, the HD line of HDMI 2.1 has not appeared on a large scale, but the DP1.4 version came out in 2016 and supports 8K. Obviously, the DP line is more mature. If your graphics card and display resolution is very high, choose DP cable, otherwise, choose HDMI cable. Among the DP line manufacturers, Cabol and Faber are in the leading position. However, at present, the cost performance and quality of Cabol DP line are relatively high.
