Unfortunately you can not connect them up with a normal VGA cable or DVI cable directly because they are different video interfaces, especially when the displays are required digital inputs.

VGA to DVI converter applications

In addition, very often VGA to DVI adapter or DVI to VGA converter needs to be used in many multimedia applications. They tend to convert a VGA format signal into a digital signal such as DVI-D or HDMI format while displaying the local signal. VGA to DVI converter and VGA to HDMI converter are invented and designed to solve these kinds of engineering problems.

As is known to all, a typical VGA DVI converter works to convert RGBHV or VGA signal displayed on analog monitors to high-resolution DVI signals. However, recently I have found one new model that can easily convert it to HDMI signal as well. If the users want to convert it to HDMI signals, what you should do is using another DVI-D to HDMI cable, which is available along with the product itself free of charge. With the help of this tool, you can achieve that the conversion from VGA to DVI-D or HDMI with ease and the resolution can be set as high as 1920 * 1080P/60Hz. What’s more, many effects can be adjusted through the button panel graphics. It is so convenient and easy to set your favorite settings like contrast, brightness, color, sharpness, and horizontal and vertical position and so on.

Product connection diagram

The host PC connects to VGA to DVI converter with a VGA cable. Normally there are two way of outputs from VGA DVI converter. One way is used to connect the VGA-enabled monitor with VGA cable and the other is used to connect to DVI equipped products like camera.

This model is a newly developed VGA to DVI converter, which can convert analog computer video signal into digital DVI signal. It is extremely useful to many multimedia applications, especially in the occasion of large-screen projection equipments with digital input ports are feeding with analog computer video signal.

Options of DVI to VGA

If you have a TV with a VGA input, you want to connect it to your computer. But the video card of your computer only comes with the DVI ports. What would be the solution then? Actually generally there are three options available as follows:

1. DVI to VGA display adapter + VGA cable

2. DVI to VGA cable

3. DVI to VGA converter

All these three options can get the job done. The first two make no difference and the last one makes sense especially when you need a DVI-D to VGA adapter. And compared to the second option, the first one would be a little bit cheaper. But the second one is more convenient.

What is DVI to VGA adapter designed for?

Due to the rapid development in the computer industry today, the product replacement becomes an inevitable trend. This will lead to interface confusion because a variety of new interfaces keep introduced between old and new equipment. DVI to VGA adapter is one of these products, which is designed for you to solve the incompatible problems that occur between devices that adopt different connectors.

Now the fact is that a lot of video cards are not equipped with VGA connector any more. In particular those high-end graphics cards only come with digital connectors like HDMI and DVI. Some would provide both one VGA and one DVI. Or some would provide simply only dual-DVI. And if you happen to have low-end LCD and CRT monitor with only VGA, a DVI VGA adapter is needed to achieve the conversion.

Mechanism of DVI VGA adapter

The DVI of a DVI VGA adapter refers to the analog DVI. So here the DVI VGA adapter means a DVI-I to VGA adapter rather than a DVI-D VGA adapter because there is the difference between analog signal and digital signal in DVI interface. The VGA signal belongs to analog signal so that the conversion can be achieved as they are the same kind of signal. Therefore, when it comes to VGA to DVI adapter, the VGA analog signal can only adapt to DVI analog signal.

There are several kinds of DVI analog signal interfaces, including DVI (24+5), DVI (18+5), and DVI (12+5) and so on. These connectors are defined as analog DVI to VGA connector by manufacturers. DVI to VGA adapters are used in the connection between VGA enabled display devices and DVI enabled computers. Simply, if your display devices such as monitors and plasma TV come with VGA port while the video output of your computer is through DVI-I port, naturally they can not be connected directly. In such case, a DVI to VGA display adapter is needed to achieve the conversion between them.

Regular DVI to VGA display adapter

Although there are special types of adapters like mini DVI to VGA adapter, the most common one is DVI female to VGA male adapter or the opposite. Of course you can find others if you would like a different combination. The usual specification is DVI-I (24+5) (male) to VGA 15-pin HD D-sub (female) connector, with gold-plated pins and nickel-plated shell.

What’s more, this DVI I VGA adapter is usually in line with SONY SS-259 standard and adopts the materials that meet ROHS standards of environmental protection. The high-end products are manufactured with fine workmanship. A quality DVI VGA adapter can withstand 300V voltage test and has excellent ability of anti-electromagnetic interference.

In such case, if you need to hook up laptop with Mini-DVI connector to VGA displays, you have to look for one out there in electronics stores.

What is Mini-DVI?

Mini-DVI is a scaled down version of normal DVI interface. This kind of connector is most seen on some Apple products, such as 12-inch PowerBook G4, the MacBook Intel-based laptop, and Intel-based iMac and the like. However, it is not the only one kind of miniaturized connector version. Other popular connectors include Mini-VGA, Mini-HDMI and Mini-Display Port and so on.

Actually, Mini-DVI was designed to be the digital superior version of Mini-VGA due to more and more machines were taking the former connectors since 2003. These kinds of connectors are quite similar at first glance. Don’t mix them up when you are ready to buy one of them.

What a Mini DVI to VGA adapter can do for you?

As we know that, DVI to VGA adapters are used to connect DVI enabled computers with VGA equipped displays. Mini DVI to VGA adapter does the same job but it is just a smaller miniature. The difference is that they are used in different applications. The former is used in standard computers and the latter is used in iMac (Intel Core Duo) and 12-inch PowerBook G4 and etc.

In practical applications, a lot of the time it needs to connect 12-inch PowerBook G4 and the like to VGA display devices like TVS, VCRS and projectors. And this is exact role a Mini-DVI to video adapter can play.

Mini DVI to Video adapter options

When it comes to DVI to VGA adaptor, it might refer to DVI-D to VGA adapter, DVI-I to VGA adapter or DVI-A to VGA adapter. They are different and you need to tell them apart when you are looking for the suitable one. As a matter of fact, the Apple mini-DVI to DVI-D cable’s package normally refers to a DVI-I figure rather than DVI-D and does not clearly point out that it offers one and sole DVI-D.

However, as the newer and more advanced connectors, like Mini-HDMI and Mini-Display Port, are introduced to the market recently. Mini-DVI is not as favorable as it was. If you have models newer than Aluminum MacBook 13-inch, the Mini-Display to VGA adapter is the one you should hunt for. Apple’s MacBook line of laptops is keeping evolve and its accessories need to catch up with the updates as well.

Choose the right Mini DVI to VGA adapter for your Apple computers

If you are using the following devices, it is no doubt that you need the help of the above-mentioned adapters. They include:

• 12-inch PowerBook G4 (not including the original 12-inch 867 MHz PowerBook G4);
• Intel-based iMac;
• MacBook Intel-based laptop;
• Intel-based Xserve;
• 2009 Mac mini.

Actually, it is one of excellent accessories for Apple computers. A lot of users just love it and it works great for them. What’s more, Mini DVI to VGA adapter is a very convenient tool to allow you connecting two display devices at the same time as the additional extension to your operating space and windows.

There are a variety of video splitter out there, including VGA video splitter, DVI splitter, RCA cable splitter, component video splitter, and HDMI splitter and the like. However, all of the mentioned splitters are just splitters with a single function – splitting the signals from the sole source in the same format.

If there are the same ports available in your computers and monitors, everything is more straightforward and simply the suitable cable splitters will get the job done easily. However, the video world is hardly perfect like you expected. Inevitably you will find that compatibility problems will just occur from time to time. In this case, a single VGA splitter cable is not the solution any more.

Now it seems that it is necessary to bring in some basic information about DVI and VGA here. VGA stands for Video Graphic Array, which is used in relatively older analog monitors. DVI stands for Digital Visual Interface, which is a superior standard to VGA and designed to take the place of it years ago. The transition from DVI to VGA is a big step forward in video technology as the change from analog to digital format marks a new display world has arrived. However, like all the innovation takes time to replace the old one although it is better, there is no exception to DVI and VGA. Therefore, the compatibility issues occur very often and thus commonly a DVI VGA adapter or DVI to VGA converter is needed to solve the problem. In addition, when it comes to DVI standard, it comes with three different types, namely DVI-D, DVI-A, and DVI-I.

In order to let the signals going through from DVI-I port to VGA port and make them function right in the terminal end displays, there are two steps must go through. Firstly, extract the analog signals from DVI-I. Secondly, transmit the signals to VGA monitor splitter and then split them. In other words, the former works like a DVI to VGA cable and the latter works like a VGA signal splitter. However, one thing you have to make sure is that your DVI port must be either DVI-A or DVI-I. As you might know that DVI-D processes digital signals only. If you want to hook two DVI enabled monitors up to DVI port, what you need is a DVI splitter cable, rather than a DVI to VGA splitter.

If you are preparing to purchase a DVI to VGA splitter, it is worthy to know that what DVI VGA splitter offers are the mirrored images in the first place. However, normally it won’t be any different from the images sent directly. For people who would like to attach two VGA displays to the PCs, DVI female to VGA male splitters are still one of the best possible solutions till now.

VGA represents Video Graphics Array, which was the major dominated technology used to hook up Mac PCs to displays back in the late 1990s. Unlike LCD monitors involving with digital signals, CRT monitors use electron beam to draw the display. Actually VGA are still one of major connections nowadays, especially to standard CRT monitors.

DVI refers to Digital Video Interface. DVI offers three types of cables, DVI-D, DVI-A and DVI-I. As we know that DVI-D is true digital signal and it can not hook up directly a DVI-D to a VGA. So when we talk about DVI to VGA cable, usually DVI cables means DVI-I or DVI-A because both of them uses analog signals. The difference between DVI-I and DVI-A is that DVI-I uses both digital and analog signals and DVI-A uses analog signals only. Since DVI-D is incompatible to VGA and they can not connect directly, if you need to connect DVI-D to VGA or VGA to DVI-D, in this case you have to use a DVI to VGA converter or adapter to transform digital signals to analog signals first, vice verse.

Although VGA is phasing out the market as newer technologies like DVI and HDMI become more and more popular today, due to its own advantages, VGA still holds the ground of its market share and provide multiple choices for consumers to choose from. That is also the exact reason why you need the help of a DVI to VGA cable now.

We just mentioned that both DVI-I and DVI-A send analog signals, so you might come to realize that DVI to VGA cables are unable to convert DVI-D digital signal to analog. A lot of people would be confused about the relations between the DVI to VGA cables, adapters or converters. Actually this cable is not digital-to-analog type like the functions provided by DVI to VGA adapter or DVI to VGA converter. The fact is that these cables just transmit the analog signals from DVI-I or DVI-A to VGA port and they don’t change the property of the signals themselves. Compared to DVI to VGA adapter or DVI to VGA converter, one of advantages of DVI to VGA cables is that it can get rid of the annoying noise coming from the adapters or converters.

A DVI to VGA cable has a DVI on one end and VGA on the other. The same is true to VGA to DVI cable. As a matter of fact, you know we are talking the same thing here. When doing the shopping, you need to be concerned about three main things. The first one is the ports. Please make sure which type of cables you are in need, DVI male to VGA female cable, DVI-A Male to VGA Male Cable or others. The second is the lengths. Normally this cable comes with 6 feet long and but you can choose a shorter or longer cord according to your requirements. The third one is the most important thing – quality. It would be a good idea to purchase those trustworthy brands such as StarTech and Newer Technology. In addition, be a savvy buyer and make the purchase especially when they are offering VGA to DVI cable with special discounts. It will definitely save you a lot of money this way.
