BL3201PT能够提供 4K@60Hz。我用DP连接的。的输出xrandr
显示以下内容:
$ xrandr -v
xrandr program version 1.4.1

$ xrandr

使用 mint 17. 有什么提示吗?
更新:顺便说一句,我的机器上有双启动,在第二个操作系统(Windows)中,刷新率为 60Hz,因为它应该是。

答案1
您的显卡和显卡驱动程序版本是什么?当我无法在 GTX 770 上的 Linux 上运行 4k 时,我只需xorg-edgers
使用命令添加 PPAsudo add-apt-repository ppa:xorg-edgers/ppa
并安装最新的 Nvidia 驱动程序,之后我就可以从 GUI 中简单地选择正确的显示选项。因此,我建议您在尝试其他操作之前尝试更新图形驱动程序。
编辑:更具体地说,您可以使用该命令sudo apt install nvidia-current
安装最新的 Nvidia 驱动程序,或者您可以使用apt search nvidia-
和sudo apt install nvidia-XXX
安装特定版本的驱动程序。
另外,请勿前往 Nvidia 网站安装驱动程序!

创建一个模式:
xrandr --newmode "10x10" 60 20 20 20 20 10 10 10 10 -HSync +Vsync
添加模式:
xrandr --addmode DP1 10x10
ps...“BadName”=您已经有同名的东西,将其丢弃或给它另一个名称。例如:
xrandr --newmode "10x10_bob1" 60 20 20 20 20 10 10 10 10 -HSync +Vsync
xrandr --newmode "10x10_bob2" 60 20 20 20 20 10 10 10 10 -HSync +Vsync
很好...
