DVI vs VGA
I bought a Samsung P2350, and it came with a VGA Cable. I have XFX 5670 1GB with 2 DVI Ports.
I've heard DVI is the best Video output. DO i need to get a DVI cable , moreever, is it available and at what cost ??
Also, should I get a DVI to VGA Converter with the graphics card package or do i need to seperately buy one ?
I felt i should add this to the first post for everybody's convenience.

DVI - information goes directly from your video card to your monitor. The color of each pixel on your monitor is calculated by your video card and then sent as digital information to your monitor so that no conversion is necessary. An LCD monitor simply reads this information and displays it directly
VGA - Information is converted from digital to [red,green,blue] format. Some accuracy and time is lost in this converstion. How much is lost depends on the monitor's conversion hardware.
Image Quality:
On a CRT monitor, there is no real image quality difference between DVI and VGA. This is because a CRT is natively based on the [red,green,blue] format for displaying each pixel.
On an LCD, you will notice a difference between the 2 formats if you look hard enough. Different LCDs will handle the conversion differently. You may start to see dithering, banding, "dancing pixels" and blander/incorrect colors when using vga on an LCD. The larger the LCD/resolution the more you will notice these differences.
DVI also has a faster data transfer rate, which means that the higher the resolution, the worse the input lag will be if you use VGA. This is very important if you play fast(twitch) shooter games.
Finally, VGA only contains the color information for your monitor's image. DVI includes more than that. That's why when you connect using DVI, you don't have to adjust your monitor's image position, phase, and clock corrections to sync. It contains exactly how/what your video card wants to display.
If you hook up your LCD with VGA, you will notice that several monitor adjustments become available were they were not under DVI. That is because DVI carries all the information your monitor needs to configure itself where as VGA does not.
