Windowsの解像度が自動で変わる

内容

WindowsのPCにて解像度をBATで変更するBATを作成しました。

背景

解像度ぐらい設定で変えろよ。となるかもしれませんが、お客様の中には解像度の変更さえめんどくさい。もしくはできないという声をいただいたので作る背景になりました。
本当は拡大率についても変更するようにしたかったのですが、レジストリを書き換えて再起動が必要なものしか見つからず、
断念しました。
良い案がありましたらコメントいただけると助かります。

#BAT
# -width 1920 -height 1080の値を変更すれば好きに設定できます。
powershell -NoProfile -ExecutionPolicy Unrestricted .\ps1\FuncChangeDisplay.ps1 -width 1920 -height 1080
start ms-settings:display

#Powershell
