# 前言 #

博主在树莓派接显示屏的时候，出现黑屏现象。经查验应该是`hdmi`的分辨率设置的问题，所以网上搜索了一下，发现可以自定义树莓派的显示分辨率。

# 树莓派显示分辨率设置 #

参考[【RPi树莓派使用指南】树莓派连接HDMI显示器及配置方法][RPi_HDMI]，具体的步骤如下：

// 打开/boot/config.txt目录下的配置文件
    sudo vi /boot/config.txt
    // 设置hdmi_group;hdmi_group可取两个值：
    // 1) 使用CEA分辨率,即hdmi_group=1;
    // 2) 使用DMT分辨率,即hdmi_group=2.
    hdmi_group=1
    // 设置hdmi_mode.对于不同的hdmi_group设置的分辨率不一样。
    hdmi_mode=31		// 表示1080p 50HZ

1.  使用`CEA`分辨率，即`hdmi_group=1`

hdmi_mode=1 VGA
    hdmi_mode=2 480p 60Hz
    hdmi_mode=3 480p 60Hz H
    hdmi_mode=4 720p 60Hz
    hdmi_mode=5 1080i 60Hz
    hdmi_mode=6 480i 60Hz
    hdmi_mode=7 480i 60Hz H
    hdmi_mode=8 240p 60Hz
    hdmi_mode=9 240p 60Hz H
    hdmi_mode=10 480i 60Hz 4x
    hdmi_mode=11 480i 60Hz 4x H
    hdmi_mode=12 240p 60Hz 4x
    hdmi_mode=13 240p 60Hz 4x H
    hdmi_mode=14 480p 60Hz 2x
    hdmi_mode=15 480p 60Hz 2x H
    hdmi_mode=16 1080p 60Hz
    hdmi_mode=17 576p 50Hz
    hdmi_mode=18 576p 50Hz H
    hdmi_mode=19 720p 50Hz
    hdmi_mode=20 1080i 50Hz
    hdmi_mode=21 576i 50Hz
    hdmi_mode=22 576i 50Hz H
    hdmi_mode=23 288p 50Hz
    hdmi_mode=24 288p 50Hz H
    hdmi_mode=25 576i 50Hz 4x
    hdmi_mode=26 576i 50Hz 4x H
    hdmi_mode=27 288p 50Hz 4x
    hdmi_mode=28 288p 50Hz 4x H
    hdmi_mode=29 576p 50Hz 2x
    hdmi_mode=30 576p 50Hz 2x H
    hdmi_mode=31 1080p 50Hz
    hdmi_mode=32 1080p 24Hz
    hdmi_mode=33 1080p 25Hz
    hdmi_mode=34 1080p 30Hz
    hdmi_mode=35 480p 60Hz 4x
    hdmi_mode=36 480p 60Hz 4xH
    hdmi_mode=37 576p 50Hz 4x
    hdmi_mode=38 576p 50Hz 4x H
    hdmi_mode=39 1080i 50Hz reduced blanking
    hdmi_mode=40 1080i 100Hz
    hdmi_mode=41 720p 100Hz
    hdmi_mode=42 576p 100Hz
    hdmi_mode=43 576p 100Hz H
    hdmi_mode=44 576i 100Hz
    hdmi_mode=45 576i 100Hz H
    hdmi_mode=46 1080i 120Hz
    hdmi_mode=47 720p 120Hz
    hdmi_mode=48 480p 120Hz
    hdmi_mode=49 480p 120Hz H
    hdmi_mode=50 480i 120Hz
    hdmi_mode=51 480i 120Hz H
    hdmi_mode=52 576p 200Hz
    hdmi_mode=53 576p 200Hz H
    hdmi_mode=54 576i 200Hz
    hdmi_mode=55 576i 200Hz H
    hdmi_mode=56 480p 240Hz
    hdmi_mode=57 480p 240Hz H
    hdmi_mode=58 480i 240Hz
    hdmi_mode=59 480i 240Hz H
    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)

1.  使用`DMT`分辨率，即`hdmi_group=2`

hdmi_mode=1    640x350   85Hz
    hdmi_mode=2    640x400   85Hz
    hdmi_mode=3    720x400   85Hz
    hdmi_mode=4    640x480   60Hz
    hdmi_mode=5    640x480   72Hz
    hdmi_mode=6    640x480   75Hz
    hdmi_mode=7    640x480   85Hz
    hdmi_mode=8    800x600   56Hz
    hdmi_mode=9    800x600   60Hz

    hdmi_mode=11   800x600   75Hz
    hdmi_mode=12   800x600   85Hz
    hdmi_mode=13   800x600   120Hz
    hdmi_mode=14   848x480   60Hz
    hdmi_mode=15   1024x768  43Hz  DO NOT USE
    hdmi_mode=16   1024x768  60Hz
    hdmi_mode=17   1024x768  70Hz

    hdmi_mode=19   1024x768  85Hz
    hdmi_mode=20   1024x768  120Hz
