Can I (programmatically) freeze Windows 10 scaling factor to 100% with Win8DpiScaling=1












0















By the Windows 10 settings option: start->system->display I can adjust scaling for each attached display to the lowest scaling factor "100%" and a highest resolution of FullHD (1080p), using two displays, each 1080p, display dimensions are 13" and 27".



When I modify the registry dword entry HKEY_CURRENT_USERControl PanelDesktopLogPixels from initial 96ppi to a higher resolution, e.g. 120dpi, and additionally set the dword entry HKEY_CURRENT_USERControl PanelDesktopWin8DpiScaling to a value of 1,

the scaling settings are automatically greyed out to a scaling factor of 175% after reboot and screen resolution appears as before.



Are there any options to tell Windows 10 to keep scaling factor at 100%, maybe programmatically via Visual Studio, using any .dll imports and .NET or some registry hacks ?
