![刷新率为 120Hz,而我的屏幕为 60Hz](https://linux22.com/image/852175/%E5%88%B7%E6%96%B0%E7%8E%87%E4%B8%BA%20120Hz%EF%BC%8C%E8%80%8C%E6%88%91%E7%9A%84%E5%B1%8F%E5%B9%95%E4%B8%BA%2060Hz.png)
我不明白为什么我的系统必须有不同的刷新率:
这是我的兰德输出:
$ xrandr
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
DVI-I-1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 443mm x 249mm
1600x900 60.0*+
1280x1024 75.0 60.0
1152x864 75.0
1024x768 75.1 60.0
800x600 75.0 60.3
640x480 75.0 60.0
720x400 70.1
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
和我的韓國输出:
$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
601 frames in 5.0 seconds = 119.982 FPS
600 frames in 5.0 seconds = 119.916 FPS
600 frames in 5.0 seconds = 119.916 FPS
600 frames in 5.0 seconds = 119.916 FPS

我有一块 nvidea 显卡。

康比兹干扰驱动程序以 120 Hz 实际刷新的能力。
您可能会花几个小时的时间思考为什么所有内容(包括glxgears
)都报告了 120 Hz 刷新率,但屏幕实际上并没有那么快更新。如果您启用了“桌面效果”或任何此类功能,请将其关闭以比较两者的xrandr
刷新率glxgears
