Sending DVI-D Signals To Different Displays

There are an increasing number of DVI cables, but the most popular type is the DVI-D cable. The movement to digital cables due to the dying market for VGA analog displays, and increasing availability of digital devices, has made the transition inevitable. Apart from the general DVI to DVI cable, many technology users are seeking to divide their video signals and deliver them to two different displays. This large increase in demand for split digital signals has made it quite difficult to find the proper DVI-D splitter solution.
The first thing to worry about when attempting to split a signal would be the output device, or video card. Not only must the video card be able to support dual link mode, but it also must be able to support a digital format. Asides from being digital, DVI cables can also be DVI-A (analog) or DVI-I (integrated). While you can use integrated or digital signals as well, analog cables can only pertain to analog devices. It should be noted that it is possible to use a DVI D to VGA converter for transitions between analog and digital.
There are two methods to split a signal, non-powered or powered. However it should be noted that non-powered devices have a higher chance of failure and are much harder to be used successfully. On the other hand, a powered device will accurately convert the signal to its proper type while also amplifying the signal. Although it is much more advantageous than a non-powered device, a powered device is fairly much more expensive than a DVI splitter cable.
It is always simplest to connect two similar devices with your system rather than use two different monitors. However this is not always possible, so it is recommended to at least maintain identical aspect ratios and resolutions. It is important to note that splitting your signal only mirrors the signal to both screens and does NOT allow for extension of your screen. As long as you are informed of what to expect from a DVI cable splitter, it should not be too difficult to find a suitable device that is proper for your needs.
