well, i asked this question the other day, and it seems no one answered! so ill try again, heres the original message, er, question:
my graphics card doesnt have dvi out, and it didnt come with an adapter, so, i went to newegg.com today and looked for some. i came across 2 different types: the one thats not an actual cable, its a solid unit and one end has the vga, and the other end has the dvi. with this, id also have to buy the actual dvi cord. the other one i saw was an actual cable, but one side had vga, the other dvi. they both adapt the signal, but which one should i get? i wanna save money and just get the cable version, but i dont know which one would most likely work better. also, if i use this adapter method, will it actually give me dvi quality picture? im a lossless kind of guy. the lossleser (er, whatever), the better!

I might be wrong, but if your graphics card does not have DVI out, there is no adapter that will let you have DVI out. DVI is a digital signal, meaning all of the information is transferred as 1s and 0s. VGA is an analog signal, meaning there are signal losses and therefore image corruption (to a very small degree.) So if the output does not start as digital, it cannot be converted to digital. So in short, there is no adapter for that.

ive seen the adapter, though! its on newegg.com. just type in "vga to dvi adapters" and youll find them. you might be right though, because once the signals analog, even if its transfered to digital, its still the same vga signal simply traveling through a dvi port...hmmm. but also, some graphics cards that dont have dvi outputs come with adapters. ahh, im confused about this... dammit!

There is some options. dont know how well they work, but at least you do have a choice.

VGA to DVI box


VGA to DVI cable

Do you have the link to the converter & cable on newegg?

My guess is that what you were looking at is the converter from DVI to VGA not the other way around.

...My guess is that what you were looking at is the converter from DVI to VGA not the other way around.

Exactly my thoughts.

The VGA to DVI Conveter Box (http://www.gefen.com/kvm/product.jsp?prod_id=1310) will do what you want, at a crazy high price. It actually says that it does make the translation from an analog signal to DVI, meaning it converts the analog signal to digital information. That is why it is overpriced. You can get another video card for waaaaay cheaper.

You cannot go from Analog RGBHV to Digital RGB (DVI-D) via a little dongle (at least not for a few bucks). The dongle you are seeing is mapping the VGA signals to the DVI-A standard. The "A" being the big point. The DVI cable spec allows passing of both digital and analog signals down a single cable.

DVI-D Digital RGB (The H & V are encoded within the datastream)
DVI-A Analog RGBHV
DVI-I Potential of either Analog RGBHV or Digital RGB

And PSST...it is still VGA...look at the spec

OK good then. I thought for a second there that the sky wasn't blue anymore.
