HDMI2. 1 and DP2.0 are relatively new versions at present, so who will be the mainstream in the future? Which is better? How should I choose? Let's take a look together ~
DisplayPort 2.0 was released in June 2065438+2009. According to VESA Association, the manager of DP2.0, the DP Alt mode can be seamlessly connected with the USB4 specification. USB4 integrates lightning and USB protocols, and will be promoted on the basis of lightning 3 free of patent fees.
USB4 adopts USB-C interface design, which means that the physical interface of DP2.0 can be transformed into a new USB type-C interface, so the interface of DP2.0 can be in two forms: DP and USB type-C.
In order to distinguish it from the common Type-C interface, DP2.0 will add a DP logo at the interface, just like there is a lightning logo next to the Thunderbolt 3 interface, so users can identify the DP2.0 interface more intuitively.
However, HDMI2. 1 is still a traditional HDMI interface, which shows that DP2.0 has more advantages, because Type-C has been widely used in mobile Internet terminal devices such as mobile phones, tablets and ultrabooks. Because of its small size, powerful functions, and the general trend of unifying peripheral interfaces.
With the help of Type-C shape, DP2.0 protocol can not only save the interface space of devices, but also realize the compatibility between different devices.
DP2.0 protocol: The theoretical bandwidth of DP2.0 is 80Gbps, which is almost three times that of DisplayPort 1.4.
Support16k @ 60hz (15360 * 8460), 8K@ 120Hz(7680*4320), 4k @144hz (3840 * 2164). Imaging and
HDMI2. 1 protocol: HDMI2. 1 bandwidth is 48Gbps, supporting 8K@60Hz and 4K@ 120Hz resolutions, and supporting 3D imaging and dynamic HDR；; 120 Hz;
In terms of parameter standards, the performance of DP2.0 protocol is slightly stronger, and it has reached a new level in bandwidth, resolution and refresh rate. The performance of HDMI2. 1 is close to the last version of DP2.0, DP 1.4.
From the above two points, it can be found that DP2.0 is better than HDMI2. 1 in terms of interface universality and performance parameters, and DP2.0 interface has another advantage for manufacturers, that is, it is free of authentication and authorization fees.
However, VESA Association has not yet announced the supporting chip scheme of DP2.0, so there is no PC display device with DP2.0 interface on the market. It can only be said that DP2.0 has great potential.
At present, DP interface mainly exists in PC field, while HDMI widely appears in all fields of life, whether it is TV, monitor, projector or game machine, and the supporting equipment is also very sound. Judging from the release time, HDMI was released earlier than DP interface, and HDMI entered the market in 2002, so everyone is familiar with HDMI.
Moreover, at present, almost all network HD resources are configured at 4k@60, and 8k video resources are rare, and 16k is almost absent, so the protocol of HDMI2. 1 can fully meet the demand. Compared with DP2.0, the application advantages of HDMI2. 1 are obvious. If DP2.0 is to be better oriented to the market, it needs the follow-up of manufacturers and consumers.
The above is a detailed comparison between DP2.0 and HDMI2. 1. What else do you want to know about DP and HDMI? Welcome to mention it in the comments section ~
