DPI awareness not working for certain apps

Hello coth,

We regret the inconvenience. Let me assist you.

Please be informed, some desktop applications (except for the Modern Apps) may appear somewhat blurry or crisp sharp when you compare them with other applications on the screen. Also, which win32 apps are you referring to in this case?

In order to provide an optimal experience on high-DPI displays, desktop applications have to detect the DPI of the display that is being used and then scale their graphical elements, text, and screen layout appropriately. Some applications do not implement
this. In some cases, the application vendor may be able to provide an updated software version that better supports high-DPI displays.

If there is no updated DPI-aware version of the application available, you may be able to alter the appearance of the application.

You can disable display scaling for an individual desktop app in Windows 10. Here’s how:

• In the search box, type the name of the app.
• Select the app’s tile and tap or click Open file location to open File Explorer on the desktop.
• In File Explorer, tap and hold (or right-click) the app’s executable (.exe) file and select Properties.
• Select the Compatibility tab.
• In the Settings section, select Disable display scaling on high DPI settings.
  
• Click OK and check with the results.

Write to us with the updated status and the required information related to DPI settings in Windows, for us to be able to assist you further.

Thank You.

 

Use secondary monitor DPI in System DPI aware applications

I run a mixed-DPI multiple monitor setup. The primary monitor is set for use with games, while almost everything else is done on the secondary high-dpi monitor.

Unfortunately this results in a poor experience for applications that are 'System aware' when it comes to DPI - they are upscaled and therefore pixelated on the secondary monitor. 'Per-monitor aware' applications work great.

Is there any way to force a system DPI aware application to run at a particular forced DPI level, rather than inheriting the DPI of the primary monitor? Windows seems to be designed around preferring the DPI of the primary monitor - I want to prefer a different DPI, without changing the primary monitor.

I imagine it is possible to force with some hooking, but before I go down that route I'm wondering if there is an option or existing solution I'm missing. It is difficult to search for this problem, as the keywords overlap with common DPI problems.

The OS in question is Windows 10.
