树莓派 外接HDMI线显示屏分辨率设置

树莓派 外接HDMI线显示屏分辨率设置

你是什么显示器，或者高清电视机，最好在没显示的情况，请将config.txt 中的分辨率调低一些，不要老想着，我的显示设备支持1080p，就非得一步到位。。。建议从下面的低分辨率尝试开始：

计算机显示器使用的分辨率 ：

hdmi_mode=4 640x480 60Hz

hdmi_mode=9 800x600 60Hz

hdmi_mode=16 1024x768 60Hz

CEA规定的电视规格分辨率。：

hdmi_mode=2 480p 60Hz

hdmi_mode=4 720p 60Hz

另外：若直接使用的是HDMI线接显示设备，请在config.txt中添加一条：

hdmi_ignore_edid=0xa5000080

这个是命令树莓派不检测HDMI设备的任何信息，只按照我们指定的分辨率输出。 这样就不会自动检测显示设备的分辨率，而避免掉很多可能不显示的造成因素，就会按照你自己设置的分辨率显示。分辨率也按照上面列出的尝试，修改config.txt 中hdmi_mode=x 的”x“值。

注意：根据http://www.raspberrypi.org/phpBB3/viewtopic.php?f=26&t=20155&p=195417&hilit=2560x1600#p195443 
有一个像素时钟限制，这意味着最高支持模式是1920x1200 @ 60 Hz，减少了消隐。
