Originally assigned to: @NickeManarin on GitHub.

When I start a DX recording containing any part of my second monitor, the recording fails to start and I get the following exception:

Object reference not set to an instance of an object.
   at SharpDX.DXGI.OutputDuplication.TryAcquireNextFrame(Int32 timeoutInMilliseconds, OutputDuplicateFrameInformation& 
frameInfoRef, Resource& desktopResourceOut)
   at ScreenToGif.Util.Capture.DirectImageCapture.Capture(FrameInfo frame)

However if I move the recording window over so that it only captures my primary monitor, the recording works fine. If I make the second monitor my "main display" in the Windows Settings app, the behavior is reversed. This might be an issue with SharpDX and not ScreenToGif, not sure.

Fantastic tool by the way, I use it all the time 👍
