【What is the difference between DVI and VGA?]
The transmission signal of DVI interface is in full digital format, which corresponds to VGA Interface of analog signal.
The difference between VGA and DVI: first, it is troublesome to transmit the VGA analog signal. First, it is to convert the digital signal in the computer into a analog signal and send the signal to the LCD display, the monitor then converts the analog signal to a digital signal to form a picture displayed in front of everyone.Severe signal lossAlthough some images can be repaired through software, the image will be blurred as the resolution of the monitor increases. AverageWhen the resolution of the analog signal exceeds 1280x1024, an obvious error occurs., The higher the Resolution, the more serious.
While the DVI digital interface can directly transmit computer signals to the displayAlmost no signal loss,At a resolution of 800x600, it is almost identical to the analog signal.This is why many people think that the DVI interface is useless. HoweverWhen the resolution is over 1280x1024, the advantages of the DVI digital interface are displayed, and the picture is still clearly visible, while the VGA interface is blurred.. The DVI interface provides a maximum transmission rate of 8 GPS,1920 × 1080/60Hz Display RequirementsHigh resolution not only provides the best picture quality for 3D movies today, but also the basic requirements of 3D graphics producers. Therefore, the popularization of DVI interfaces will be an inevitable trend in the development of the digital era.
