Do I need a DVI connector to use my Digital Monitor?

Question

I just bought a digital LCD monitor to replace my flat screen analog monitor, hoping it will get better picture quality. However, it comes with two connection cables. One is a VGA cable and the other is a DVI cable. I can only connect the VGA cable and USB cable to the back of my computer. There isn't a DVI connector. I'm using a DELL Dimension E310. So am I screwed? Am I still getting Analog picture quality even though it's a digital monitor?

Answer 1

Short answer is NO, you don't need to.

Long answer:
I will be quoting excerpts from wikipedia.org to explain the
different. If you want a good understanding, I recommend that you read
the articles in their entirety:

VGA: http://en.wikipedia.org/wiki/VGA
DVI: http://en.wikipedia.org/wiki/Dvi

The main difference is that VGA is an analog standard for computer
monitors that was first marketed in 1987, whereas DVI is a newer and
superior digital technology that has the potential to provide a much
better picture.

Here are two relevant excerpts from Wikipedia for your convenience:

"Existing standards, such as VGA, are analog and designed for CRT
based devices. As the source transmits each horizontal line of the
image, it varies its output voltage to represent the desired
brightness. In a CRT device, this is used to vary the intensity of the
scanning beam as it moves across the screen. However, in digital
displays, instead of a scanning beam there is an array of pixels and a
single brightness value must be chosen for each. The decoder does this
by sampling the voltage of the input signal at regular intervals. When
the source is also a digital device (such as a computer), this can
lead to distortion if the samples are not taken at the centre of each
pixel, and in general the crosstalk between adjacent pixels is high."

"DVI takes a different approach. The desired brightness of the pixels
is transmitted as a list of binary numbers. When the display is driven
at its native resolution, all it has to do is read each number and
apply that brightness to the appropriate pixel. In this way, each
pixel in the output buffer of the source device corresponds directly
to one pixel in the display device, whereas with an analog signal the
appearance of each pixel may be affected by its adjacent pixels as
well as by electrical noise and other forms of analog distortion."

PS - personal note:
if your eyes are human, as most of ours are, you are unlikely to notice the difference between the 2 types of input.

Answer 2

Yes, you're still getting Analog picture quality even though it's a digital monitor, unless you upgrade your graphics card w/ DVI.

Answer 3

terrific place is Intramuros and Rizal Park. circulate to Casa Manila, San Agustine Church, Manila Cathedral, citadel Santiago. after which you would be able to circulate to Rizal Park, chinese language backyard, Butterfly Pavilion, All of those places are interior strolling distance. deliver water that's a delightful walk yet you will would desire to rehydrate. maximum Filipinos have not been in touch with their roots,and traveling those places might positioned a beneficial smile and a terrific thank you to locate history and one yet another all in the comparable time.

Answer 4

Usb should be able to give digital quality
