What is a DP interface?
The DP interface, the DisplayPort interface, is a display interface released by the Video Electronics Standards Association (VESA). As the successor of DVI, DisplayPort adds support for high-definition audio signal transmission while transmitting video signals, while supporting higher resolution and refresh rate. 
In addition, it can support single-channel, one-way, four-wire connections, data transfer rate of 10.8Gbps, enough to transmit uncompressed video and related audio, and also supports 1Mbps bidirectional auxiliary channel for device control, in addition to Supports 8-bit and 10-bit color.
In data transmission, DisplayPort uses the "micro-packetised" format. With a high degree of scalability, you can continue to add more new content in the future.
4K TV with DP interface
For Xiao Bian’s understanding of the situation, currently the Panasonic AX800C is the only 4K TV with a DP interface, and its practicality is self-evident.
In the current HDMI 2.0 output device is not popular, through the DP 1.2 interface can be connected to high-end PC to achieve 4K@60p signal input, this should be the most easy to achieve the 60-frame 4K signal input program.
Panasonic AX800C looks like a picture frame, hollow base is completely attached to the desktop, that is to say AX800C TV looks only the picture and "picture frame", as if it is quietly set on the table, no extra elements, a more visual field Pure and capable. 
The system function interface always keeps a real-time preview of the video input source. In the specific application, when you watch TV, you need to call an application. After you call up the homepage menu, you can still watch the TV picture through the dynamic preview of the small window.
Seeing here, some friends may feel very curious, what is the difference between it and HDMI interface? Especially the HDMI2.0 interface.
The difference between DP interface and HDMI interface

The biggest difference between the DP interface and the HDMI interface is that the sizes of the two interfaces are different. The size of the HDMI interface is closer to the USB interface, and the DP interface is larger. This can be seen from the naked eye. As for the clarity of the image, with the birth of the HDMI2.0 interface, the clarity of the HDMI interface and the DP interface is almost the same, and it is difficult to separate the secondary BER, and it can output 4K@60 frames.
DP interface 4K TV and HDMI interface 4K TV which is better? Judging from the maturity of the market, devices that currently use the HDMI2.0 interface are far more than the DP interfaces, and have the opportunity to become the mainstream interface type in the future. They can be connected to more external devices, and their external expansion performance is stronger.
Do you know 4K TV with DP interface? In the current HDMI 2.0 output device has not yet been popular, through the DP 1.2 interface, 4K TV can also achieve 4K@60p signal input, which should be the most easily implemented 60 frame 4K signal input program. So who is this DP interface 4K TV? What is the DP interface?
