Hello guys,im asking behalf of my friend sincr i couldnt give an explanation to him..he is playing his xbox360 using lcd monitor and he ask me if there any major different between using vga hd cable and dvi cable,i already said to him dvi deliver more sharper image quality but he still keep insisting about vga hd,what is the best explanation to end his'degil'ness,if he is not my friend i already ignore it since im of those'jenis malas nak layan'..

so far i have yet to see any official xbox360 DVI cable, there is only VGA/HDMI/Component/Composite that i know of, VGA can deliver almost same quality as in HDMI for 1080p, component its a replacement for those user's tv that doesnt support HDMI/VGA or old model of xbox360 that doesnt comes with HDMI port. as of composite its for CRT TV max 480p.

anyway i dont think i can see the difference using VGA cable/ DVI cable for other device like desktop PC.

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.
