ubuntu 14.04 HDMI错误分辨率

我最近购买了 NVIDIA GTX960，但通过 HDMI 电缆（使用 HDMI 转 VGA 转换器）连接的辅助显示器出现了问题。有问题的显示器是 Acer X233H，分辨率为 1920x1080。

但在可用的分辨率列表中，只显示这一点：

khan@khan-P55A-UD3P:~/Desktop$ xrandr 
Screen 0: minimum 8 x 8, current 2726 x 768, maximum 16384 x 16384
DVI-I-0 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 410mm x 230mm

   640x480        59.9  
   512x384        60.0  
   400x300        72.2  
   320x240        60.1  
DP-4 disconnected (normal left inverted right x axis y axis)
DP-5 disconnected (normal left inverted right x axis y axis)

如果我尝试手动添加分辨率，则会出现以下错误：

khan@khan-P55A-UD3P:~/Desktop$ cvt 1920 1080 60

有人能指出哪里出了问题吗？我应该DisplayPort 至 VGA 转换器（ nvidia 960 有 3 个 DisplayPort、1 个 HDMi 和 1 个 DVI ）这样能解决问题吗？

我知道这是一个老问题。你肯定早就解决了这个问题。

对于遇到此问题的其他任何人，我通过前往/etc/X11/xorg.conf并修改监视器HorizSync和VertRefresh值解决了此问题。我不记得它们是什么，但这就是监视器部分现在显示的样子。

Section "Monitor"
    ....
    HorizSync       30.0 - 83.0
    VertRefresh     56.0 - 75.0
    ....
EndSection
