Hi SГ©bastien,
Your clients have blurriness because the Desktop Window Manager (DWM) virtualizes and scales the application to account for high DPI.
For more info please read the "Writing DPI-Aware Desktop and Win32 Applications" article:
https://msdn.microsoft.com/en-us/librar ... s.85).aspx
and the "Developing a Per-Monitor DPI-Aware WPF Application" article:
https://msdn.microsoft.com/en-us/librar ... s.85).aspx
We will add support for "per Monitor–DPI Aware Applications" in our WPF viewers in future version of SDK.
Best regards, Alexander
