Opera 100% DPI parameters changed

  • Just wanted to let people know, in case you need opera to be set at 100% while windows is set at other scale. (I wanted to add this to an old post but not possible, so here I am)

    The launcher flag for me until earlier today used to be:


    but now it changed to be like Chrome:

    /high-dpi-support=1 /force-device-scale-factor=1

    So I'm just using both for now (in case Opera goes back to the old one), like this:

    "C:\Program Files\Opera\launcher.exe" --alt-high-dpi-setting=96 /high-dpi-support=1 /force-device-scale-factor=1

    Remember you might need to relog or restart windows so this works correctly.

  • Thank you! Seems that /force-device-scale-factor=1 is key.

    What I want, but Opera devs have not implemented (and probably never will), is to keep UI at 120dpi (125%), but tabs content at 96dpi (100%) - otherwise either UI is too small for me to use or images and some flash content (geni) cannot be displayed properly.

  • Thank you! You saved my life! 🙂

  • God its abt 5 years with this "feature" to change DPI, and they even change it to make things more complicated. Add this to options already, such a disgrace
