GPU 卡通过显示端口->HDMI 连接时屏幕分辨率错误 Ubuntu 18.04.2 LTS (BadMatch (无效参数属性))

Question

我的屏幕分辨率为 1920x1080，但我可以获得 2520x1080（lg25UM58）。我的卡通过显示端口（GPU）连接到此屏幕，再连接到 HDMI（屏幕）这是连接器的问题吗？您有什么想法吗？

这是我的配置：

sudo lshw -C display

Nvidia 驱动程序是 430，获取方式如下

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-driver-430 nvidia-settings

我该怎么做才能强制解决？我尝试

cvt 2560 1080 60

输出

# 2560x1080 59.98 Hz (CVT) hsync: 67.17 kHz; pclk: 230.00 MHz
Modeline "2560x1080_60.00"  230.00  2560 2720 2992 3424  1080 1083 1093 1120 -hsync +vsync

添加模式

xrandr --newmode "2560x1080_60.00"  230.00  2560 2720 2992 3424  1080 1083 1093 1120 -hsync +vsync

xrandr --addmode DP-0 2560x1080_60.00

这给了我这个错误：
