The total, complete, borderline-intimidating package
From the four ports pictured above spring all of the input and output connections necessary to make an All-In-Wonder feature set possible. The left-most port is where you connect the antenna for the FM tuner, and next to it is the port for the coaxial input from the cable network or a TV antenna. On the far right is a DVI port for connection to a computer monitor; it can also be used with a VGA-to-DVI converter, but ATI doesn't supply one with the AIW X1900. That's because you can get a VGA output from the small black port in the middle, along with lots of other things.
This is the dongle that plugs into that square, black connector next to the DVI port. From it comes a blue VGA connector, a black video output port, and a purple video input port. These last two ports don't connect to a video source or destination directly; instead, they feed ATI's stackable input and output blocks.
These fancy plastic doodads are the I/O blocks, which use a Lego-like connection to stay fastened together. The block on the top plugs into the purple port on the dongle and has inputs for S-Video, composite video, and left and right stereo audio channels. This is where you can hook up your VCR in order to pull family videos into your PC. The middle block is the opposite deal; it's for output of the same sorts of things. The connector block on the bottom is for component video output to HDTVs and the like. The trio of green, red, and blue ports are the three traditional component outputs, while the red and white ports on the right areyou guessed itleft and right audio out. The two output blocks cannot be used simultaneously. The card will drive either one of them, but not both at once.
Here's the other end of the cable coming from the component video output block. The red plug connects to the dongle. You can also see the green connector for analog audio. This plugs into the line out on the PC's sound card, and it has a pass-through for external speaker systems. There's also an orange SPDIF output plug, and a blue plug for analog audio output.
The other end of the composite/S-Video output cable is essentially the same as the component one, and the purple cable from the input block is nice and simple.
