DIV
The transmission signal of DVI interface adopts full digital format, and the corresponding VGA interface adopts analog signal. The difference between VGA and DVI is that the transmission of VGA analog signal is troublesome. First, the digital signal in the computer is converted into analog signal, and the signal is sent to the LCD display, which then converts the analog signal into digital signal to form a picture for display. Because of this, the middle signal is lost seriously. Although some pictures can be repaired by software, However, the higher the resolution of the display, the more blurry the picture will be. Generally, analog signals exceed 1280 × If the resolution is higher than 1024, obvious errors will occur. The higher the resolution, the more serious the error will be.
The DVI digital interface can directly transmit the computer signal to the display, with almost no signal loss in the middle × At this resolution, the effect is almost the same as that of analog signals, which is why many people think that DVI interface is useless. But at 1280 × When the resolution is above 1024, the advantages of DVI digital interface are shown. The picture is still clear, while the VGA interface is illegible. DVI interface can provide up to 8GPS transmission rate, realizing 1920 × 1080/60Hz display requirements, high resolution can not only provide the best film quality in today's 3D film special effects flooded, but also is the basic requirement of 3D graphics producers. Therefore, the popularization of DVI interface will be an inevitable trend in the development of the digital era.
