强制HDMI

hdmi_force_hotplug：强制树莓派使用HDMI端口，即使树莓派没有检测到显示器连接仍然使用HDMI端口。该值为0时允许树莓派尝试检测显示器，当该值为1时，强制树莓派使用HDMI。

分辨率

针对hdmi_group的两套分辨率如下所示，通常我们使用hdmi_group=2。
使用查表法配置hdmi_mode。

H means 16:9 variant (of a normally 4:3 mode).
2x means pixel doubled (i.e. higher clock rate, with each pixel repeated twice)
4x means pixel quadrupled (i.e. higher clock rate, with each pixel repeated four times)
