Hi,

This library has issues dumping all of the data to an XML file because it can't be serialized due to many of the classes not having parameterless constructors.

I've fixed this and will do a pull request shortly.

Thanks for a great library!

Hi,
Noticed that current release does not have latest in-repo changes, is there any plan to release them?

First of all, awesome API, thank you so much ❤️.

Apologies if I'm missing something obvious here but (in some places) I'm seeing Identity as return value where I was expecting a value. For example like below, taken from the WindowsDisplaySample demo program. Using version 1.3.0.13.

All pointers appreciated.

Hello,

I tried to use the new version of Your library and it seems that enabling displays stopped working.
The sample throws an exception for "DeviceContext: Enable All" in

var validSetting = display.DisplayScreen.GetPreferredSetting();

because display.DisplayScreen is null. I tried to enable displays in my code via API call but it did not work either.

My Setup is the following:

• Dell Precision 7510
• 2x FUJITSU E24-9 TOUCH

When using your library, I do not get "E24-9 TOUCH" as DisplayName. On stackoverflowis a solution to get this information:

• https://stackoverflow.com/a/28257839/6229375

Maybe it would be possible to retreive this information and also a display name from the internal laptop screen?

Hi!

It seems like wrapper have some troubles with detecting displays on Win11.

Display.GetDisplays() returned empty collection.

Could you clarify, it is compatibility issue or it's on my side?

Hi

I'm working on a little project that will allow me to store display settings for all 4 of my monitors and then let me restore those settings at a later time.

However, I've run into issues with Display.Enable which calls 'displaySetting.Save' which in turn uses the 'ScreenName' property. From what I can see this won't really work, and is not for me currently, as the 'ScreenName' property won't be consistent when switching a display between on and off. I'm not 100% sure if this is a bug or if I'm just doing it wrong. I've actually had a bit of a hard time getting this far and so it's possible I'm just doing something wrong.

For example, let's say I have 2 displays and both are currently ON.
If I call 'WindowsDisplayAPI.Display.GetDisplays()' I will have a list of 2 and the 'ScreenName' for each will be as follows.

\\.\DISPLAY1
\\.\DISPLAY2

Now if I call Disable on the second display, the ScreenName property in the DisplayScreen class will be: \.\DISPLAY2

So far things are working and the second display will be disabled.
If I now call 'WindowsDisplayAPI.Display.GetDisplays()' I will have a list of 1 display and it's 'ScreenName' will be:
\\.\DISPLAY1

However, I need to call 'WindowsDisplayAPI.UnAttachedDisplay.GetUnAttachedDisplays()' to get the disabled Display I want to turn back on and it's 'ScreenName' is now also:
\\.\DISPLAY1

This means that when I call Display.Enable, the 'ScreenName' property in the DisplayScreen class is: \.\DISPLAY1

So now the API is enabling the Display that's already active and not the second display. I am getting the correct display to enable, but because the 'ScreenName' is now the same as the active display's 'ScreenName' the wrong display is being made active due to the use of ScreenName when calling 'displaySetting.Save'. This call can be found at:
file: DisplayScreen.cs
line: 114

I first thought maybe it's because I'm in a Win10 VM, but I made a WPF demo project to test this and I get the same behavior on my main Windows 10 Desktop.

Hi All,
Is there any way to get "Active signal resolution", there is no way to get it in the WindowsDisplayAPI project

Error Message:The parameter is incorrect.

Hi,

I couldn't find it in library (maybe I missed something). I am looking for DPI scaling information for each display.

Possible to add to library?

Thanks!

Is there a workaround to enabling an unattached display when GetPossibleSettings() doesn't return anything?

Also when the same display is enabled it correctly returns all possible display settings.

Thanks.

Hello,
First, I would like to thank you for your library. It is very useful.
I saw that last release was on Feb 10, 2020 and since, there has been 7 commits.
Can you please release a new version for nugget ?
Thank you.

I trying to retrieve number of monitor where my wpf app is running. TIs possible to retrieve that data with WindowsDisplayAPI?
Winform method retrieve that data, but there is no correlation on numbers with what windows display config menu show.

More of a question than an issue, can we set the orientation?
I see the DisplayOrientation, but can we set? Or just a get?

I have all references under a WPF .net core 6 project and cannot access display.GetScreen()

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net6.0-windows10.0.22000.0</TargetFramework>
    <Nullable>enable</Nullable>
    <UseWPF>true</UseWPF>
    <UseWindowsForms>true</UseWindowsForms>
    <SupportedOSPlatformVersion>10.0.19041.0</SupportedOSPlatformVersion>

Anything I am missing?

Please implement serial number extraction from EDID block.

Excellent library, I have used it for many months and I never had an error. Exceeding this
System.ComponentModel.Win32Exception (0x80004005): Unsupported request
in WindowsDisplayAPI.DisplayConfig.PathInfo.GetPathInfos(QueryDeviceConfigFlags flags, DisplayConfigTopologyId& topologyId)
in WindowsDisplayAPI.DisplayConfig.PathDisplayTarget.GetDisplayTargets()
in ...

I would like to get the bounds of a monitor (height, width and size) but unsure how to get it.
If you do not mind, could you please point me in the right direction?

Thank you in advance.

Trying this awesome package I stumbled over an error. I thought I report it here.

I use nuget package version 1.3.0.13. Im on win10 and run a winforms project with creating a "console build". i use vs 2019 and .net framework 4.7.2.

I start the programm just like in the example and things work but when i try the DeviceContext: Enable All option an exception occurs

console: ModeChangeException - Error: [Failed]: Applying saved settings failed.

visual studio output: Exception thrown: 'WindowsDisplayAPI.Exceptions.ModeChangeException' in WindowsDisplayAPI.dll

stacktrace from exception from debugger:

}
