正如你所看到的，我使用的是1680x1060@120hz，但如果我尝试使用1920x1080@144hz，屏幕就会变黑，信号也是如此！！！！
xrandr --output DVI-0 --mode 1920x1080 --rate 144.0 DONT WORK
xrandr --output DVI-0 --mode 1920x1080 --rate 144 DONT WORK
xrandr --output DVI-0 --mode 1920x1080 --rate 120.0 DONT WORK
xrandr --output DVI-0 --mode 1920x1080 --rate 120 DONT WORK
为什么 1680x1050 在 120hz 下工作正常，而我的高分辨率 1920x1080 却不行？？？
