无法使用外接显示器的最大分辨率“xrandr：配置 crtc 0 失败”

我有一个 1440p 显示器，通过 HDMI 电缆连接到我的笔记本电脑，我无法将其设置为最大分辨率，它只能保持在 2048x1080 (9:5)。我尝试使用以下代码来设置最大分辨率：

cvt 2560 1440
#Modeline "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync

xrandr --newmode "2560x1440_60.00"  312.25  2560 2752 3024 3488  1440 1443 1448 1493 -hsync +vsync

xrandr --addmode HDMI-1-2 2560x1440_60.00


xrandr --output HDMI-1-2 --mode 2560x1440_60.00

但是，我一直收到这个错误：

xrandr: Configure crtc 0 failed

我该如何解决这个问题？
