HDMI interface is widely used in various multimedia entertainment devices such as TVs, monitoring equipment, high-definition players, home game consoles, etc., while DP is mainly used in graphics cards and computer monitors. Both are high-definition digital interfaces, which can provide high-definition video and audio output at the same time, so people often compare the two.
DP1.4 has a bandwidth of 32.4Gbps and supports 4K 120Hz and 8K 30Hz. Before HDMI2.1 was launched, DP1.4 can be said to be better than HDMI2.0 in an all-round way. DP has also become the mainstream interface of graphics cards because it can support higher refresh rates, but TVs and projectors still use HDMI2.0 Interface, after all, there are few video resources with high resolution and high frame rate, and HDMI 2.0 is completely sufficient.
With the increasing popularity of high-resolution and high refresh rate resources, HDMI2.0 has gradually lost its advantages. Many people hope that TVs and projectors can also use DP1.4 interfaces. However, with the introduction of HDMI2.1 with larger bandwidth and lower cost, the DP1.4 interface also lost its advantages.
