That's the way it looks from creating in the 4k monitor at 225% and moved to the 1080p 100% monitor. Looks fine going back to the primary monitor but not on creation, as it looks small on creation.

(I'll be removing these pics later on after you've seen them to save space in my user usage)  Using imgbb.

I hope you don't mind me doing something similar in parallel.

Actually, I'm the one that should say that !. Am "piggy back" from your code
And yes, I'm working on it on my side as we speak post. I'm thinking of posting my progress later ( say 6 hours ) on my thread

We ( in the AutoIt project/forum ) may have overlooked this need for years but we have to acknowledge that is needed.

@argumentum thanks for testing. Which os you are using?

Btw, you can upload image here: imgbb.com and link it directly to the forum.

I'll explore imgbb, thanks for the idea.

Posted ( as a ZIP ) what I was gonna post in 6 hour, so we can compare notes.

@UEZ ,

 I realize this is not the information you're asking for but I want to share.
Take notice of the clarity of the text in the 2 pics attached.

For completeness, I suggest you open taskmgr.exe and then switch that to Details View.
Rightclick the Header row and choose "Select columns" - scoll to near the bottom and select  [x] DPI Awareness
This will display the awareness state of the executible.

Of the 2 pics attached, the 1st one is using your code with no modification, and the second one is using
#AutoIt3Wrapper_Res_HiDpi=Y with the exe's manifest containing

<asmv3:application>
    <asmv3:windowsSettings>
    <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">True</dpiAware>
    </asmv3:windowsSettings>
</asmv3:application>

Some of the function are not supported by server os.

 

@Shark007 which os you are using? When I use #AutoIt3Wrapper_Res_HiDpi=Y then WM_DPICHANGED will be by-passed and the clarity is gone.

 

[Shark007]

I am on Windows 11 22H2

I use a personally modified version of AutoIt3Wrapper.au3 because I wanted the exact code I posted above in my manifests.

#AutoIt3Wrapper_Res_HiDpi= ??? Should be researched because there are different ways to invoke DPI awareness such as Monitor V1 and V2 etc.

 

EDIT, also know, those screenshots were taken @ 350% on a 4K monitor.

2. I used your posted code to create those exe's with the only diff be the manifest change.

Edited August 1, 2023 by Shark007

..whatever we put together should work anywhere from WinXP/Server2003, all the way to the present.
If the DllCall(s) worked then it works, else, run as we didn't even try. But should look blurry as not DPI aware, or just fine.

..we'll get there

My AutoIt3Wrapper.au3 section:

If $INP_RES_HiDpi <> "n" Then
                    FileWriteLine($hTempFile2, '    <asmv3:application>')
                    FileWriteLine($hTempFile2, '        <asmv3:windowsSettings>')
                    If $INP_RES_HiDpi = "p" Then
                        Write_RC_Console_Msg("Setting DPI awareness Manifest information to true/PM", "", "...", 0)
                        FileWriteLine($hTempFile2, '        <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">True/PM</dpiAware>')

I cannot remember if I changed it or Jos.

.. the manifest portion looks the same on my side. Compiled as described but not with the same results as of @Shark007's.
I mean, with _HiDpi=p and _HiDpi=y but it looks tiny.

Edit: I'm on win 10, not 11. I'd have to try that in Win11 but nonetheless, whatever we put out there should be as functional as possible, even if it takes an extra sacrifice to the gods of the code ( in the form of code, I faint at the sight of blood )

Edited August 1, 2023 by argumentum

[Shark007]

I omit the whole HiDPI=Y section of AutoIt3Wrapper.au3 because I wiped out that whole section and replaced it with this because this performs best for dragging from one monitor to another and I am unconcerned of not using Awareness.

FileWriteLine($hTempFile2, '<asmv3:application>')
                FileWriteLine($hTempFile2, '    <asmv3:windowsSettings>')
                FileWriteLine($hTempFile2, '    <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">True</dpiAware>')
                FileWriteLine($hTempFile2, '    </asmv3:windowsSettings>')
                FileWriteLine($hTempFile2, '</asmv3:application>')

All software I create is DPI Aware.

should do the same, unless you removed more than just that ?

[Shark007]

Yes.  I took that whole section out and put in the few lines I posted above.

So I have no need for  #AutoIt3Wrapper_Res_HiDpi=Y because the inquiry became redundant.

Edited August 1, 2023 by Shark007

..went Win11 (remote desktop) at 300% and tried compiled ( green icon ) and the UDF we're working on ( blue icon )

... you may have to open to view it elsewhere as the image could be bigger than your monitor.

[UEZ]

This DPI stuff is very tricky because of different os with different behavior.

Let's see where we end... 😉

I tested (not compiled!) with 200% on main screen and moved to 100% and back again. It looked good.

[argumentum]

..same, 

that in actuality looks more like this, size wise to my eyes ( did a 50% reduction on mspaint. The pic is uglier than reality  )

Now, going back and forth, it gets to this:

these pics are from the 4k @ 225% as primary monitor.

[argumentum]

...the 100% looks like this:

[argumentum]

this is a good idea for these testings and running the scripts from anywhere:

Func AutoItExe_Path() ; AutoItExe_Path() & "\Examples\GUI\SampleAVI.avi"
    Return StringLeft(@AutoItExe, StringInStr(@AutoItExe, "\", 0, -1) - 1)
EndFunc

Edit: the main PC I'm using has a portable setup. No RegRead()   

Edit2: This is better:

Func ExamplesGUI_Path() ; ExamplesGUI_Path() & "SampleAVI.avi"
    Local Static $imgPath = IniRead(@AppDataDir & "\AutoIt_HiDpi_Testing\defaults.ini", "path", "ExamplesGUI", @CRLF)
    If $imgPath = @CRLF Then
        If @Compiled Then
            Return ""
        Else
            DirCreate(@AppDataDir & "\AutoIt_HiDpi_Testing")
            IniWrite(@AppDataDir & "\AutoIt_HiDpi_Testing\defaults.ini", "path", "ExamplesGUI", StringLeft(@AutoItExe, StringInStr(@AutoItExe, "\", 0, -1)) & "Examples\GUI\")
            $imgPath = IniRead(@AppDataDir & "\AutoIt_HiDpi_Testing\defaults.ini", "path", "ExamplesGUI", @CRLF)
        EndIf
    EndIf
    Return $imgPath
EndFunc

and is better than writing to registry 🙄

100% at main monitor:

 

100% at main monitor to 200% second monitor:

 

100% at main monitor to 200% second monitor and back to 100% main monitor:

 

200% at main monitor:

 

200% at main monitor to 100% third monitor:

 

200% at main monitor to 100% third monitor and back to 200% main monitor:

 

After the DPI change the title size of GUI stays at higher size!?!?!

 

Tested on Win11 22H2.
