    Window 10 - blurry text in non-high DPI aware apps - try to fix it


    I upgraded to the Windows 10 becouse I was looking forward to per monitor DPI feature. This feature works well - except for the non-high DPI aware apps. These apps are rendered using DPI virtualization and appear blurry on high DPI displays. I've read some MS articles about it - the application is rendered using standard 96 DPI and then scaled up. Which seems wrong to me. The base DPI should be configurable!

    I have a high-DPI display in my laptop and sometimes use classic external display. Why should I suffer blurry apps on my main display? If I use the "all displays same DPI fix" all apps are sharp. So if the base render DPI would match main display, I could get sharp image. And the scaled-down window on external display should look much better than the scaled up window.

    I assume the value of render DPI isn't a registry key, but it is a hardoced constant in code. But it should be possible to change it with some nasty dissassembling, etc. I am not afraid of it. However I have no clue, where to start looking for it. Could you help me?

    So, the component responsible for the rendering/composition is DWM (Desktop Window Manager (Windows)).
