Recording the secondary screen

[HPBotma]

Hi - I can't seem to get the library to record the second screen? [Screen connected to my laptop via HDMI].

It records the primary screen fine, but if I select only the second screen for recording - it throws an exception "The parameter is incorrect".

If I choose to record both screens simultaneously, I get no errors, but on playback, there is a blank spot where the second display should be.

i use the snippet from the example project to configure the sources: RecorderOptions options = new RecorderOptions { SourceOptions = new SourceOptions { RecordingSources = sources } }; _rec = Recorder.CreateRecorder(options);

Not sure why the second screen is called display 4 [see image] - as there is nothing else connected? Any advice would be greatly appreciated

Does it work if you swap the recorder API from Desktop Duplication to Windows Graphics Capture? Desktop duplication is older, and have known issues with laptops with both integrated graphics and discrete graphics.

Thanks for the quick response! However, I am not sure where to change the recorder API ? the example project does not seem to make any mention of it?

It's the property RecorderApi on the DisplayRecordingSource object. Edit: On the sample project, you can select it on a dropdown next to the monitor name and path.

Great - works well! Thanks for all the effort in creating and maintaining this library

SourceOptions = new SourceOptions { RecordingSources = { new DisplayRecordingSource { DeviceName = DisplayRecordingSource.MainMonitor.DeviceName,RecorderApi = RecorderApi.WindowsGraphicsCapture } } },

added this option but still records main monitor only, anyone facing same?
