DVI与VGA的区别

date:On November 01, 2017 Source:  

   DVI和VGA看上去很像,都是针形接口的一种,可是工作传输原来又是怎样的一种原理呢,区别在于什么。现在市面上的DVI线、DVI光纤、DVI延长器等这些主打的设备,广泛用于各种需求当中,为什么DVI还那么的流行与于现在的这个年代里呢,和VGA对比还是有些出入的,这个就从信号方面可以指出,下面来探秘一下吧。

DVI and VGA look like, are a needle-like interface, but the work of the original transmission is what kind of principle, the difference lies in what. Now on the market DVI cable, DVI fiber, DVI extender, and so these main equipment, widely used in a variety of needs, why DVI is so popular and now in this era, and VGA contrast or some out, This can be pointed out from the signal, the following to explore it now.


   DVI


   DVI(DigitalVisualInterface),即数字视频接口。它是1999年由SiliconImage、Intel(英特尔)、Compaq(康柏)、IBM、HP(惠普)、NEC、Fujitsu(富士通)等公司共同组成DDWG(DigitalDisplayWorkingGroup,数字显示工作组)推出的接口标准。

DVI (DigitalVisualInterface), that is, digital video interface. It is an interface standard introduced by companies such as SiliconImage, Intel (Intel), Compaq (HP), IBM, HP (HP), NEC, Fujitsu (Fujitsu) and other companies in DDWG (DigitalDisplayWorkingGroup) The.


   VGA


   VGA(VideoGraphicsArray)是IBM在1987年随PS/2机一起推出的一种视频传输标准,具有分辨率高、显示速率快、颜色丰富等优点,在彩色显示器领域得到了广泛的应用。不支持热插拔,不支持音频传输。使用模拟信号的一种视频传输标准。

VGA (VideoGraphicsArray) is IBM in 1987 with the PS / 2 machine launched a video transmission standard, with high resolution, fast display speed, rich colors, etc., in the field of color display has been widely used. Does not support hot swapping, does not support audio transmission, the use of analog signals, a video transmission standard.


   知道了两者的输出信号类型不同,就知道了区别,DVI可输出1920*1080的全高清数字信号,VGA因为是模拟信号,效果没数字信号好。若接的是高清电视机,一般的只能最高输出1366*768,区别就是在此。

Know the difference between the two output signal types, you know the difference, DVI can output 1920 × 1080 full HD digital signal, VGA because it is analog signal, the effect of no digital signal is good. If connected to the high-definition TV, the general output can only be the highest 1366 * 768, the difference is here.
