Can't use parameters of DisplaySwitch.exe in Windows 8. RRS feed

  • Question

  • In Windows 7, users can use parameter just like "/clone", "/extend" or "/internal" appending to DisplaySwitch.exe to switch between different presentation modes (duplicate, extend or display only). However, I found that these parameters can't work in Windows 8. If I use them, just only a slide shows on the right and let me select presentation mode, but it can't switch like Windows 7.

    Is it a bug of Windows 8? And will it be fixed in the later version or not? Thanks.

  • I don't think the tool's command line is documented, and undocumented stuff tend to stop working sooner or later. 

    Of course, nothing prevents some programmer to write a clone by calling SetDisplayConfig with parameters like SDC_TOPOLOGY_CLONE, SDC_TOPOLOGY_EXTEND, SDC_TOPOLOGY_INTERNAL or SDC_TOPOLOGY_EXTERNAL.
