Hello guys. Sorry i'm a noob in the LCD section.

After decades of using CRTs, i've upgraded to an LCD monitor yesterday. Its a BenQ FP92W 19" widescreen. So far im impressed with it, although its a little too wide for me. Gonna take some time to get used to it.

I have a question. What is DVI-D? The monitor does not come with the cable and the shop fella said it is optional. I didnt buy it yet coz i have no idea what it is. How does it help performance wise? And do i need to change my cables if i use it? I'm currently using the usual blue coloured port connected to the monitor and my rig.

Thanks crazybear and davidmak for your help. Was so blur before this. Definitely gotta get a DVI cable next.
