화면 해상도를 변경하기 위해 Powershell(또는 기타) 스크립트를 수행하는 방법은 무엇입니까?

화면 해상도 변경(예: 1024*768)을 어떻게 스크립팅할 수 있습니까?

답변1

해상도를 설정하는 기본 Powershell 방법은 없습니다. 이를 수행하려면 Powershell 스크립트에 인라인 C# 코드를 작성할 수 있습니다. 그렇지 않으면 이를 수행하는 타사 명령줄 응용 프로그램을 찾아서 스크립트에서 호출해야 합니다.

Andy Schneider는 다음을 통해 화면 해상도를 변경할 수 있는 스크립트를 작성했습니다.핀보케그리고디스플레이 설정 변경Win32API. 에서 받으실 수 있어요TechNet 갤러리. 도 있습니다Timothy Mui 버전으로 수정됨다중 모니터를 지원하는 이 스크립트의

다음은 경우에 따라 수정된 스크립트 자체입니다.

# NAME: Set-ScreenResolutionEx.ps1 
# AUTHOR: Timothy Mui (https://github.com/timmui) 
# DATE: Jan. 7, 2015 
# 
# DESCRIPTION: Sets the Screen Resolution of the specified monitor.  
#              Uses Pinvoke and ChangeDisplaySettingsEx Win32API to 
#              make the changes. Written in C# and executed in PowerShell.  
# 
# KEYWORDS: PInvoke, height, width, pixels, Resolution, Win32 API,  
#           Mulitple Monitor, display 
# 
# ARGUMENTS: -Width : Desired Width in pixels 
#            -Height : Desired Height in pixels 
#            -DeviceID : DeviceID of the monitor to be changed. DeviceID  
#                        starts with 0 representing your first monitor.  
#                        For Laptops, the built-in display is usually 0.  
# 
# EXAMPLE: Set-ScreenResolution -Width 1920 -Height 1080 -DeviceID 0 
# 
# ACKNOWLEDGEMENTS: Many thanks to Andy Schneider for providing the original 
#                   code for a single monitor resolution changer.

EBGreen이 말했듯이 Powershell은 바닐라 상태에서는 이를 수행할 수 없습니다. 그러나 .NET 기반 셸이므로 Powershell 스크립트 내에서 .NET을 사용하거나 기존 CLI 애플리케이션을 사용하거나 Cmdlet을 작성하여 이를 수행할 수 있습니다.

해당 경로를 더 자세히 탐색하기로 결정한 경우 다음 링크가 도움이 될 수 있습니다.

답변4

기본 Windows 명령을 사용하여 이 작업을 수행할 수는 없지만 다음과 같이 명령줄에서 호출되는 응용 프로그램을 사용할 수 있습니다.http://www.pcdownloadworld.com/prgdb/reschange.htm.

나는 전에 그것을 사용해 본 적이 있습니다. 조금 번거롭지만 주석에 적힌 대로 작동합니다.
