The DVI (Digital Visual Interface) connector is gaining popularity in LCD flat
panels as well as DLP video projectors. As the data to be displayed is digital to
begin with, it makes little sense to convert the signal to analog, pass it through
a VGA-style connector, and then convert it back to digital form again in the
display device. The DVI connector solves this by keeping the signal in the
digital domain all the way.
The advantages include a rock-solid image, no pixel jitter and best possible
image and color precision. This is usually provided with little, or no, need for
manual adjustment, resulting in improved image consistency and stability.
The high speed digital signal makes it more difficult to run long cables or to
distribute the signal to multiple display devices. However, solutions to these
needs are beginning to appear from some manufacturers as the DVI standard
gains in popularity.

A few other digital display connection standards also exist, more or less similar
to the DVI standard. Most of them share the pros and cons of DVI, and differ
mainly in terms of maximum display resolution or refresh frequency.
