I just received a 22" monitor and it came with a DVI-D cable and a VGA cable. Originally I plugged in just the VGA but out of curiosity I checked my graphics card and it supports a DVI-D connection.
So, I unplugged the VGA and plugged in the DVI-D cable.
I'm not sure if there is supposed to be a difference visually.
I also don't know if you are supposed to have both plugged in together or just the DVI-D by itself.
Thanks in advance,
Sean

DVI-D will give a better picture.
All LCD monitors are digital. So the monitor has to sample the analog signal and convert it. It needs to do this at the center of each pixel, but there is no signal from the system to tell the monitor when this is. So the monitor has to look at the video signal and reverse engineer the pixel clock to work out where to sample. As you go up in resolution this gets harder as the pixels become shorter periods of time. A poor video card and EMI fixes on the system and monitor make this harder too as the signal takes time to change from one pixel to the next. The result can be a slight shimmer or jitter in the screen. The auto setup routines have gotten a lot better, but are not always perfect. A DVI-D link gets rid of this problem.
Only connect one.
Unless you want to run an extended desktop across the one monitor, using the monitor's input select button to switch between the left and right sides of your extended desktop. (Not worth it IMHO.)

The adapter that was supplied was probably to connect to a DVI-I socket which has digital and analogue output. You are now left with a DVI-D socket which is digital output only so, an adapter is your only answer. On a quick google found this adapter for AU$59.95. Have a look around but this is about the cheapest you are likely to find by ant method

I believe that DVI-D is digital while VGA is analog. VGA cable has to convert from analog to digital while DVI cable is digital-ready. There should be more boost in performance for DVI-D, although probably it is not easy to discern through casual use.

above answers are correct....just keep in mind that you usually need to go with vga to get a display when you want to access the bios or run a boot other than direct into windows. you can just swap the cables if the situation presents itself

DVI-D gives u a crispier picture. U only need to hook up to DVI-D and not VGA
