Connecting via DVI
If your display has a DVI input as shown in Figure 1-6, you will need an adapter. HDMI and
DVI have very similar electrical signals, so adapters are
passive
- that is, they don't contain
any electronics, just two sockets with wires in between. You can buy cables with an HDMI
and DVI connector or adapters as shown in Figure 1-6 for less than £5.
Connecting via VGA
DVI and HDMI both work with
digital
signals and are only found on newer monitors. Older
monitors with VGA use
analogue
signals and as such need some sort of electronic circuit to
convert between them. You can buy adapters that convert between HDMI and VGA for
about £20 online. he Pi-View device shown in Figure 1-7 is designed speciically for the
Raspberry Pi and is available through element14.
