DVI-D is Xiami Dongdong

Simply put, it is a digital signal interface. At present, only some high-end LCD monitors with such an interface will become the technical product of mainstream interfaces of the display in the future. The complexity is: with the development of display technology, especially the wide application of digital LCD, DLP and PDP products, traditional VGA analog signals do not meet the development needs, many applications are replaced by digital visual interfaces (DVI. In the simulated display mode, R. g .. B signal is converted into analog signal through D/A in the video card. After transmission, it enters the display. After processing, drive R. g .. the whole process of the B electron gun is simulated. The numeric display mode is different. g. after the B signal reaches the display device (LCD, DLP, PDP, etc.), it is processed by A/D and converted to a digital signal, subsequently, a digital signal is used to control the signal board's transmission or reflection light, or the DMD Chip's reflection light, or the plasma reflection, to achieve the display effect. In this process, it is obvious that there is a conversion process from number to analog to number, with a large loss of signal, and there will be problems such as tail dragging, blur, and shadow. In today's devices, computer graphics cards with digital interfaces are quite common, and even laptops are equipped with DVI interfaces. In addition, most display graphics processors have even only digital signal interfaces, more and more display devices are equipped with digital signal interfaces. Therefore, digital-to-digital applications are mature.
