DVI-D to VGA

DVI-D to VGA - Plenty of worthy ideas for DVI D to VGA cable, converter/adapter and related products like DVI-D to HDMI cable and VGA to HDMI cable etc.

DVI-D to VGA cable, converter and adapter is very often being mixed up with DVI-A to VGA and DVI-I to VGA adapter, cable and converter since they are so similar to each other. However it won’t cause you a big trouble even if you plug them mistakenly. The only consequence and inconvenience thus caused is that your computer and monitors won’t work for you as you expected it to be. To make it right and choose the suitable DVI to VGA adapter, cable and converter for your devices, you need to tell the differences between them first.

As for the signals transmitted through DVI connections, it is either analog or digital format. As we know that analog signal and digital signal are not compatible to each other at all. So problems will occur if you connect them up by mistake. For example, you are trying to put through a device with only analog signals output to a device with only digital signals input with VGA cables. That is also true that if you put them through the other way around. As just we mentioned, they are foreign to each other and unable to communicate with the foreign languages.

DVI (Digital Visual Interface) is a video interface that features both digital and analog signals. As we know that VGA (Video Graphics Array) is a format that used in older CRTs for analog signals. Normally flat LCD panels have both digital DVI and analog VGA. DVI-D refers to digital signals only. As we have stated just now, DVI-D doesn’t allow any analog signals to run through except for digital signals from DVI-D or HDMI because DVI-D format is totally incompatible with analog signals like component, VGA and composite video and so on. If you compare sockets between a DVI-D to VGA adapter and DVI-I to VGA adapter, you will find that DVI-I has extra four pin sockets around the flat ground pin, which is dedicated for the analog signals. DVI-D has no such socket so that it can only deal with DVI-D or HDMI devices. For more information about relationship among these three common video interface, please also refer to DVI-D to HDMI cable and VGA to HDMI cable.

As we just mentioned that DVI-I socket has four pin sockets for analog signals. So what does DVI-I socket mean? DVI-I socket means that you can use it for the following three types of occasions. The first type is DVI-D only, which permit only DVI-I cable to connect with as it has no pins for analog signals. The second type is DVI-A only, which receives only normal analog signal format like RGBHV. The third type is DVI-I, which can process both digital and analog signals through the port once it detect and handle them separately and automatically. For more information between the first two versions, please also refer to DVI-I to DVI-D cable.

So what is a DVI to VGA converter, adapter and cable should be used for? Presume that you have a computer with DVI video card and VGA monitors and projectors, they won’t work for your if you simply plug them on with a VGA cable or DVI cable. Or you can discard all your VGA monitors and replace them with displays of DVI or HDMI format. However, I believe not all of you are willing to pay that sum of money since the old one are still in good shape. It is exactly where a DIV to VGA cable, converter or adapter comes for. This DVI to VGA adapter, cable and converter makes it a possibility to continue using the existing VGA monitors in an economical way.

So we return to DVI D to VGA converter, adapter and cable. As we know that DVI D to VGA converter can do the job to convert signals from DVI D to VGA since it is a converter. But how does a DVI D to VGA adapter and cable work since DVI D allows digital signals only and VGA allows analog signal only? What is the difference between DVI D to VGA cable/adapter and converter? The situation of DVI D to VGA is much complicated. Actually, to use DVI D to VGA adapter/cable, you need a video card with the VGA to DVI-D conversion function on your PC first, which is the key you can use them. On the contrary, a DVI D to VGA converter doesn’t need the conversion function on your PC and it can convert it on its own. Now we come to realize that all DVI D to VGA converter, adapter and cable need the conversion process. The only difference is the conversion takes place before or after going through DVI D plug.

And another possibility for DVI D to VGA adapter is that some devices provides some kind of nonstandard wiring setup, which supports to route analog VGA signals via a DVI D socket. However, this occasion is rarely seen. In addition, if this function is there, the manual will tell you how to do without a doubt.

If you have finished the above information about DVI-D to VGA cable, converter and adapter, we believe it won’t be a difficult thing any more for you to choose a suitable DVI to VGA product. You see, DVI-D, DVI-A and DVI-I is not as confusing as you thought before now.
