刷新率为 120Hz,而我的屏幕为 60Hz

刷新率为 120Hz,而我的屏幕为 60Hz

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
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 4999 requests (4999 known processed) with 0 events remaining.

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
