It's time again to pop open the virtual mailbag, which overflows with insightful questions from inquisitive readers.

This week's first query comes from a reader who recently upgraded from an old CRT monitor to an LCD. When connecting the new monitor to his computer, he noticed that there are two output jacks to choose from, labeled VGA and DVI. Although his existing monitor cable -- as well as the cable that came with the LCD monitor -- only fits the VGA jack, he wondered what the difference is, and more importantly, if he's missing out on something.
