How to disable high DPI scaling for autoit GUI?

[E1M1]

Hi!

 

When I use my autoit GUI with high DPI monitor, it gets blurry because of faulty scaling. How do I disable scaling for my GUI? I tried SetProcessDPIAwareness but it does not seem to work.
 

$__eDPIAWARNESS_Process_DPI_Unaware = 0
$__eDPIAWARNESS_Process_System_DPI_Aware = 1
$__eDPIAWARNESS_Process_Per_Monitor_DPI_Aware = 2

Func _WinAPI_SetProcessDPIAwareness($iPROCESS_DPI_AWARENESS)
    Return DllCall('Shcore.dll', 'int', 'SetProcessDPIAwareness', 'int', $iPROCESS_DPI_AWARENESS)
EndFunc   ;==>_WinAPI_SetProcessDPIAwareness

_WinAPI_SetProcessDPIAwareness($__eDPIAWARNESS_Process_Per_Monitor_DPI_Aware)

$gui =  GUICreate("Title")
GUICtrlCreateLabel("Hello World", 10, 10)
GUISetState(@SW_SHOW)

while GUIGetMsg() <> -3
WEnd

Thanks!

Just in case anyone arrives here from search engine. The solution was:
 

DllCall("User32.dll", "bool", "SetProcessDPIAware")

if I do the DllCall from _WinAPI_SetProcessDPIAwareness() outside a function, right on the script, it works as expected. But somehow, not working within the function

_WinAPI_SetProcessDPIAwareness is a privately defined function possibly originating with the user, InnI

My research reveals that It is not a working standard.

It is recommended that you set the process-default DPI awareness via application manifest, not an API call.

my research on this topic is posted here as previously linked in the 2nd post above.

It has the insight you seek.
