how can i change screen resolution in windows 10 Enterprises using command prompt or powershell or registry keys? RRS feed

  • Question

  • i have been trying powershell scripts , through command prompt and registry keys too but nothing seems to work.i want to change screen resolution to  1280*1024

    i used below script as it was given as a solution to change resolution

    Function Set-ScreenResolution { 

            Sets the Screen Resolution of the primary monitor 
            Uses Pinvoke and ChangeDisplaySettings Win32API to make the change 
            Set-ScreenResolution -Width 1024 -Height 768    -Freq 60    
    param ( 
               Position = 0)] 
               Position = 1)] 

               Position = 2)] 


    dm.dmPelsWidth = width; 
                    dm.dmPelsHeight = height; 
                    dm.dmDisplayFrequency = freq;


    Set-ScreenResolution -Width 1024 -Height 1280 -Freq 24 
    $pinvokeCode = @"

                return dm; 

    Add-Type $pinvokeCode -ErrorAction SilentlyContinue 

    but it doesnot work and throws "failed to change the resolution"

  • You will have to ask the author of the code for help.  Much of what you have posted seems to be missing and the code is not structured correctly.
