我已经尝试过的事情

我的笔记本电脑上连接了一台外接显示器。当前设置为 1920x1080p@60Hz。我想将其设置为 1920x1080p@75Hz。我在 Windows 8.1 中使用此刷新率已有一年多，没有出现任何问题。可以通过 DisplayPort 或 HDMI 连接显示器。

Kubuntu 17.10
Nvidia gtx 960m
Nvidia 驱动程序版本：384.98

更新2018/09/26：

仍然无法正常工作。我甚至进行了全新安装。

Kubuntu 18.04
Nvidia 驱动程序 390.48

我已经尝试过的事情

格式：

我找到说明的页面

命令
结果

更改特定显示器的刷新率

xrandr --output DP-3 --rate 75

什么都没发生。

xrandr --output DP-3 --mode 1920x1080 --rate 75

“未检测到输入/信号”

xrandr --output HDMI0 --mode 1920x1080 --rate 75

屏幕上下摇晃/振动。

如何设置我的显示器分辨率？

有用（我认为）。
