Qt and 4K Resolution

  • Hallo,

    I have a huge problem. I changed my second Display to another 4K Display. So both Monitors are now 4K. Now no Qt Application have a GUI. They stopped displaying any Graphical User Interface. They seem to work and Messageboxes appear But the usual GUI disappeared. Only QT is affected. other GUI Libraries work without issues.

    Before I had a Display with 2560x1440 and it was without any problems.

    Why is QT so problematic with 4K Displays?

    MicroSIP is affected

    You should add:

    • which OS ?
    • which version of Qt ?
    • which graphics card ?
