A few years back you might have started to notice that newer graphics cards and monitors were coming with an extra input, it was the white multi pin DVI input which stands for digital video interface. Since most new computers and monitors will come with this DVI input as standard it's probably a good time to make the most of it, especially if you're not yet setup for HD. But is there actually any difference between the two in terms of picture quality? Let's take a look.

VGA and how it works - Reading about how a VGA signal works might leave you a bit confused, this is because the signal begins as digital when it is generated by the graphics controller, it then travels across the VGA cable as an analog signal until it reaches the other end (the monitor) and is then converted back to digital. This might seem like an inefficient way of doing things and in reality it is. For a standard CRT monitor there shouldn't be a problem with this kind of setup, this is because the CRT monitors draw the display using an electron beam, this passes over the coating that is inside the monitor.

The problem does occur however with LCD monitors. For an LCD monitor to display a VGA signal it needs to do an image map that will basically map each pixel on the screen to the correct colour. To achieve this it must applying a clocking and synchronising scheme. This is all good and well until things get out of sync, when this happens you will experience blurring or banding and this can negatively impact the quality of the picture.

DVI and it's improvements over VGA - DVI is a definite improvement over VGA for the simple fact that the signal is now an all digital signal, from start to finish. That means there is no conversions from digital to analog and because of this there is no synchronising that needs to be applied.

With the signal now all digital you will get a clearer picture and a faster display transfer, this will more or less correct the problem with banding that you might get with a VGA display. With DVI you get three types of cable which are:

DVI-D or 'true digital' as they are called is the standard used to connect a computer graphics card to a DVI enabled monitor DVI-A cables are used to connect a DVI input to a VGA monitor. They are not very common as most graphics cards either have both outputs (VGA and DVI) or if you have a DVI only graphics card you are likely to have a DVI ready monitor! DVI-I are cables that are able to transfer from digital to digital or analog to analog and are again not very common

So as you can see DVI cables are an improvement over VGA although in a real world scenario it is unlikely you will see a massive improvement like you would with HD. With that being said they are very widely available and are certainly better than using the old VGA technology.
