I know very little about computers. Got a new computer with a LG w2252tq monitor. When it starts up "analog" comes on the upper right hand corner for a few seconds before it dissapears. I'm not sure if my monitor is digital or analog. So if I hook up a DVI cable would that be a digital signal? If so where would a good place to buy one? Best buy wanted about a $100.00.... thanks for the help..........
