问题描述
我编写了一个脚本，将主屏幕方向更改为纵向.我的屏幕是1920X1200 它运行并且没有错误报告.但是屏幕没有按照我的预期旋转.
I wrote a script to change primary screen orientation to portrait. my screen is 1920X1200 It runs and no error reported. But the screen does not rotated as i expected.
该代码已从Set-ScreenResolution(Andy Schneider)中修改.
有人可以帮我看看吗?
The code was modified from Set-ScreenResolution (Andy Schneider).
Does anybody can help me take a look?
