HDMI-VGA转换器黑屏的排障方案

这个配置提供了HDMI的所有故障排除用的保守设置。
请将SD卡插入电脑,将这些内容存为config.txt。(原来的config.txt可以备份一下。)


hdmi_force_hotplug=1

config_hdmi_boost=4

hdmi_group=2

hdmi_mode=9

hdmi_drive=2

hdmi_ignore_edid=0xa5000080

disable_overscan=1

解释:
hdmi_force_hotplug:强制使用HDMI输出(强行认为HDMI口已经插入了设备)
config_hdmi_boost:HDMI信号增强。
hdmi_group、hdmi_mode:决定分辨率。group=2, mode=9 代表800×600 @ 60Hz。
hdmi_drive:强制音频输出到HDMI口(注意,仅适用于带音频的HDMI-VGA转换器!!如果想让音频从模拟输出,则去掉此项!!)
hdmi_ignore_edid:强行按hdmi_group和hdmi_mode规定的分辨率输出。不检测显示器自身的分辨率。
disable_overscan:强行禁止保留黑边功能。

这个文件会命令树莓派:强制使用800×600分辨率,60Hz刷新率,并强制从HDMI输出。
请先尝试这样开机。如果开机能成功,就把hdmi_group和hdmi_mode,更改成自己显示器的分辨率即可。
所有可用的分辨率列表请见:自定义树莓派的显示分辨率
如果不行,请更改hdmi_mode的值更换以下其他分辨率:


hdmi_mode=4    640x480   60Hz

hdmi_mode=9    800x600   60Hz

hdmi_mode=16   1024x768  60Hz

hdmi_mode=17   1024x768  70Hz

hdmi_mode=23   1280x768  60Hz
