Thread: HiDPI scale issue

    Unhappy HiDPI scale issue

    Hello and thank you for reading my issue. I appreciate this might be the 1000000 time someone write about this issue, however, after several attempts and reading I'm still unable of making this to work.
    My external monitor is a 4k monitor, whereas the laptop monitor has reguar dpi. Many apps works just fine, such as the new installed ones, firefox, chrome etc. Nonethe less, apps such as yast, dolphin and kate have a weird behaviour I am attaching a picture to illustrate my problem.
    I dont care about scaling, in fact, I would like to keep the scale = 1. Everything looks normal at my "lowDPI" monitor, but when i open the apps in the HiDPI, all the menus, icons and letters get huge and many time intelligible.

    What should I try?... I played with the environment varibales QT_AUTO_SCREEN_SCALE_FACTOR and QT_SCREEN_SCALE_FACTORS... still no joy. Any clue?

    BR, Ariel

    Default Re: HiDPI scale issue

    You could try using xrandr to scale and pan the HiDPI display image as described here

    https://wiki.archlinux.org/index.php...tiple_displays
    and also mentioned in this thread
    https://unix.stackexchange.com/quest...monitor#217715

    If you can get the xrandr configuration providing the output that you desire, it can then be made persistent by executing the command via KDE's 'Austostart' function so that it takes effect after logging in.

    System Settings > Startup and Shutdown > Autostart...
    openSUSE Leap 15.1; KDE Plasma 5
