Thank you for sharing the issue and I am sorry about the experience!

Based on the Bug ID, it looks like there is something wrong with the graphics card when you open ARCHICAD 22 using the external display, either the machine is trying to use the wrong card, or Antialiasing must be turned off. Since you are using macOS, here are a few suggestions to try:
  • Please disable the automatic graphics card switching with this tool:
  • If the above tool cannot help, antialiasing should be switched off in the preferences. Please follow the steps below:
  • In the respective AC folder under
    Applications/GRAPHISOFT/ARCHICAD 22 XXX/Defaults/ARCHICAD/WorkEnvironment/User Preferences/Standard User Prefs 22.xml
  • [list=]
  • The following line needs to be adjusted:


    The above "1" needs to be changed to 0.
  • Afterward, please do a Preferences cleaning

    Note that in this case this only worked after a reboot of the computer.

    Please let me know if the above suggestions help. Thank you very much!

    Not applicable
    We are hooked up only to the dedicated graphics using an RTX 2080.
    Desktop PC not a laptop.

    If we enable spanning via the Nvidia control panel it works, however snapping toolbars and windows does not work as we intend it. Spanning in Nvidia treats the 2 monitors as 1 and doesn't actually think of them as separate screens.
