如何解决树莓派Raspberry连接micro HDMI无法显示？

第一次插上micro HDMI转HDMI线后，显示器会出现黑屏，或者提示调整为最佳分辨率。

1. 拔出TF卡，用读卡器放入PC打开config.txt文件。
2. 把下面的几个语句uncomment掉

# uncomment if you get no picture on HDMI for a default "safe" mode
hdmi_safe=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
overscan_left=16
overscan_right=16
overscan_top=16
overscan_bottom=16

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
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

其中mode需要根据显示器的最佳分辨率来设置，此处16代表1080p 60 Hz。
