Raspberry Pi - HDMI to VGA 到電腦螢幕

1. 原廠的Raspberry Pi只支援HDMI介面，如果想要把Raspberry Pi透過VGA介面接上螢幕，需要先購買HDMI to VGA的轉接器。

2. 原本的Raspberry Pi的設定，會把畫面輸出至HDMI，如果想把畫面透過VGA輸出至螢幕，必須修改/boot/config.txt。

$ sudo vi /boot/config.txt

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=16

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
hdmi_drive=2

2.1 Force the monitor to HDMI mode so that sound will be sent over HDMI cable
hdmi_drive=2

2.2 Set monitor mode to DMT
hdmi_group=2

2.3 Set monitor resolution to 1024x768 XGA 60 Hz (HDMI_DMT_XGA_60)
hdmi_mode=16
