Bagaimana saya bisa skrip perubahan resolusi layar, misalnya ke 1024 * 768?
Bagaimana saya bisa skrip perubahan resolusi layar, misalnya ke 1024 * 768?
Jawaban:
Tidak ada cara PowerShell asli untuk mengatur resolusi. Anda dapat menulis kode C # in-line dalam skrip PowerShell untuk melakukannya. Kalau tidak, Anda perlu menemukan aplikasi commandline pihak ketiga yang melakukannya dan cukup memanggilnya dari skrip Anda.
Andy Schneider menulis sebuah skrip, yang dapat mengubah resolusi layar melalui Pinvoke dan ChangeDisplaySettings Win32API. Anda bisa mendapatkannya di galeri TechNet . Ada juga yang dimodifikasi oleh skrip versi Timothy Mui , yang mendukung banyak monitor.
Berikut adalah skrip yang dimodifikasi itu sendiri, untuk berjaga-jaga:

# 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.

Seperti yang dikatakan EBGreen, Powershell tidak bisa melakukannya dalam kondisi vanilla-nya. Namun menjadi shell berbasis NET, Anda bisa menggunakan .NET dalam skrip PowerShell, menggunakan aplikasi CLI tradisional atau menulis Cmdlet untuk melakukannya.
Tautan ini dapat membantu Anda keluar jika Anda memutuskan untuk menjelajahi jalur tersebut lebih lanjut:
Lihat QR freeware :
Deskripsi: Utilitas baris perintah untuk mengubah resolusi layar, kedalaman warna dan kecepatan refresh ...
Untuk kasus beberapa monitor, Anda dapat melihat Display Changer (gratis untuk penggunaan pribadi dan pendidikan):
Display Changer mengubah resolusi tampilan, menjalankan program, lalu mengembalikan pengaturan awal. Itu juga dapat mengubah resolusi secara permanen dan mengatur ulang monitor dalam pengaturan multi-monitor. Ini berguna untuk game dan komputer home theatre.
Anda tidak dapat melakukan ini menggunakan perintah Windows asli, tetapi Anda dapat menggunakan aplikasi yang dipanggil dari baris perintah seperti http://www.pcdownloadworld.com/prgdb/reschange.htm .
Saya telah menggunakannya sebelumnya - ini sedikit rumit tetapi melakukan apa yang tertulis di kaleng.
