一.临时调整分辨率
1.打开终端,执行以下命令查看当前支持的分辨率:
xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 16384 x 16384
HDMI-1 disconnected (normal left inverted right x axis y axis)
DP-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.00*
800x600 60.32 56.25
848x480 60.00
640x480 59.94
1920x1080_60.00 59.96
HDMI-2 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
HDMI-3 disconnected (normal left inverted right x axis y axis)
DP-3 disconnected (normal left inverted right x axis y axis)
2.若需要 1920*1080分辨率,执行:
cvt 1920 1080 60
3.复制输出的Modeline字符串 "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync,然后运行:
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode DP-1 "1920x1080_60.00"
xrandr --output DP-1 --mode "1920x1080_60.00"
二.永久设置分辨率
将以下命令添加到/etc/profile 文件末尾 :
echo 'xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync' >> /etc/profile
echo 'xrandr --addmode Virtual1 "1920x1080_60.00"' >> /etc/profile
重启后生效
