Analog Connection	DVI Connection
Supported	Supported

Analog video connections are the type of VGA interface most commonly in use at the moment but the 181T offers support for both Analog and Digital connections.

The basic differences between an analog display adapter and a DVI (digital) display adapter is that with the blue analog cable, the image is transmitted to your monitor as an analog signal.

On the DVI cable, the images arrives at the display as a digital stream of one's and zero's. When these display signals are sent to an LCD display via an analog cable, the picture must be translated to a digitally signal before it can be processed and shown.

On the other hand, if you happen to have a digital DVI output on your video card, the digital signals are simply sent right to the display to be shown on the screen. Is there a difference between the two ways of connecting to a LCD display? Well yes an no. On the visual level there are not that many user perceivable differences in display quality that you will notice.
