Win8ScreenDriverImpl can't be successfully initialized

[tiagocunico]

Hello, it works normally until I connect my 3 monitor on my normal HDMI output. I was looking on the logs and apparently the problem is the way It's using the Win8ScreenDriverImpl.

This is the log i received, i linked the full log too.

[18300/ 9812] 2021-07-26 13:50:21:111 ! Win8ScreenDriverImpl Catched Exception in the Win8ScreenDriverImpl::execute() function: Unable get all DXGI outputs for virtual screen. The exception will consider as critical [18300/ 9812] 2021-07-26 13:50:21:212 ! Win8ScreenDriverImpl has an invalid state. The invalid state can be a part of screen propery changes. An update signal will be generated as a screen size changed signal.

i got this code here, i suppose It's something close to the problem I'm facing.

// Check that all outputs for the virtual screen are found (in case two or more // hardware graphic interfaces are used). It's better to avoid using buggy // Desktop Duplication API here rather than getting the wrong framebuffer. Screen screen; if (screen.getVisibleMonitorCount() != dxgiOutputArray.size()) { throw Exception(_T("Unable get all DXGI outputs for virtual screen")); }

if you have any idea what is happening, or how can I fix it, let me know. currently, I'm unable to use the adapter.

thanks for your attention.
