Intro To DVI-I To VGA Splitter Cable
DVI, which stands for Digital Visual Interface was created in order to replace the old standard of VGA input which has served the technological community for several years. DVI input has allowed the world to slip into the digital world, but with many people not ready to upgrade to the new technology, transitioning between VGA to DVI has become a problem for many people. One of the temporary solutions to this problem is using a DVI splitter, but that does not solve the problem of needing both an analog and a digital signal.
In order to accomplish this, the DVI output that is being used must be DVI-A or DVI-I. These notations on the end of DVI stand for analog and integrated, which determines the kind of signal the input will accept. Purchasing a DVI I to VGA splitter will in most cases solve the problem and purchasing a cable to perform this task means you can upgrade in the future to full digital without having to retain the old analog technology.
Of course, splitting the signal this way makes sense, but in practice there can be other problem you will need to overcome. The most common of these is that a splitter cable will only provide a mirrored image across both monitors and does not extend the desktop which is what most people want to accomplish. If you want extra workspace by having two monitors attached to your computer, you will need to purchase a video card that is capable of supporting two monitors with two different DVI output plugs, as splitting the signal and extending it across monitors is not the answer to this problem.
Signals split in this manner are ideal for classroom use, where the professor can attach his computer screen to an HDTV that supports DVI input and can then display his computer screen to the class without the need for having a projector to make the screen larger.
