有时当我连接第二台液晶显示器(iiyama ProLite E2407HDSV)
Native resolution Full HD 1080p, 1920 x 1080 ( 2.1 megapixel)
Horizontal sync 30-81 KHz
Vertical sync 56-75 Hz
到我的 Asus N56J 笔记本电脑
15.6" IPS 1920 x 1080 ( Full HD )
当我尝试使用 LCD 扩展我的笔记本电脑显示器时,出现错误:
could not set the configuration for crtc 64
经过几次尝试,它确实起作用了,错误也消失了。此外,当我进入显示设置时,我得到了一个透明窗口,如下所示:
此外还安装了以下附加驱动程序:

答案1
根据你的外接屏幕的规格,我建议你更改设置以匹配它的原始分辨率。根据您的 xrandr 输出,您已将其配置为 1600x1200 @ 60 Hz 制造商建议做的事情之一(在手册中)在联系饭山信息热线之前,请先检查“是否正确原始分辨率已通过‘显示属性’选择”。
要设置使用制造商推荐的分辨率,您需要使用 生成一个模式行cvt
。由于这是 TFT 显示器,而且我找不到任何相反的迹象,因此我使用刷新率 60 来生成模式行。
因此你可以用以下命令生成模式行:
cvt 1920 1080 60
其结果输出类似如下内容:
1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
然后你可以使用 xrandr 应用模式行:
xrandr --newmode
一切从 cvt 输出的 Modeline 之后
包括引文进而
xrandr --addmode VGA1 1920x1080_60.00
其中 VGA1 是显示器连接的端口,其余部分是 cvt 输出引号之间的所有内容
