The DVIs

There are two types of signals that can be carried through a DVI cable: Analog and Digital. Not every DVI connection carries both signals. If you are connecting a DVI source to a VGA/Component analog display then it is important to know if your source carries an analog signal. As a simple rule, Computer DVI ports typically support analog signals, whereas DVD players, and satellite/cable boxes do not usually support analog output.

1. To start off, look at your DVI connection. If it has a Horizontal bar surrounded with pins, then it is a DVI-I connection which may or may not carry a analog signal. If it doesnt have the pins then it only sends digital signals.

2. If it has those pins, then double check with the manual for the device to see if it supports analog through put. It wwill be in the specifications section and may say Analog, RGB, or VGA. If it doesnt say, then the next best step is to contact the manufacturer to see what it supports.

If your DVI port supports analog input then you can use DVI to VGA converters. If you need to connect to a component analog display, then you may be able to use a DVI to VGA cable.

If your DVI port does not have analog throughput, then you may want to use another connection on your device. The other option is to convert the digital signal to analog using a DVI to VGA converter.
