Do I need a DVI connector to use my Digital Monitor? - dvi digital
I bought a digital LCD monitor to replace my analog flat panel monitor, hoping to get a better picture quality. However, it comes with two connection cables. One is a VGA cable and the other is a DVI cable. I can VGA cable and USB cable to the back of my computer. There is a DVI connector. I use a Dell Dimension E310. I'm screwed? I still get the analog image quality, even if it is a digital monitor?

The short answer is no, you do not need.
Long answer:
I quote excerpts from wikipedia.org explain
different. If you want a good understanding, I recommend you read
Articles in their entirety:
VGA: http://en.wikipedia.org/wiki/VGA
DVI: http://en.wikipedia.org/wiki/Dvi
The main difference is that this is a standard VGA analog computer
Monitors that are placed on the market in 1987, while DVI is a new and
superior digital technology with the potential to offer a wide
a better image.
Two relevant passages from Wikipedia for convenience:
"Existing standards such as VGA are for analog CRT
Based devices. As the source transmits each horizontal line of the
The image varies its output voltage to the desired pose
Brightness. In a CRT device, this method is used to vary the intensity of the
Scanning beam as it moves across the screen. However, digital
Sample, instead of a beam is an array of pixelsand
single brightness value should be chosen for each. The decoder is
by sampling the voltage input signal at regular intervals. When
the source is a digital device (eg a computer), this can
lead to distortion if the samples are collected at each center
Pixels, and in general, the interference between adjacent pixels is high. "

"DVI is a different approach. The desired brightness of pixels

At its native resolution, everything you need to do is read to each issue and
apply to each pixel brightness. In this way each
Pixel in the output buffer of the source device corresponds directly to
A pixel on the display device, while an analog signal from
Appearance of each pixel with its neighboring pixels can be affected as

PS - ofPersonal note:
If your eyes are human, like most of us is unlikely that the difference between the 2 types of entries.
