The recent anouncements by IBM included several new displays which are
driven by analog signals rather than digital signals like the old displays.

The way I understand it, digital signals on PCs are made up of four signals,
red, green, blue, and an intensity signal giving 16 colours. How does analog
work? What are the advantages of analog over digital? Does it allow for higher
frequency of scan rate and thus more colours and higher resolution?

Thanks in advance for the answers!
