Some laptops have dual GPUs, if that is the case often you will need to force which GPU will be used by NDI Screen Capture. On my Dell Precision, which has Intel and nVidia GPUs, NDI Screen Capture only works correctly if the Intel GPU is used.

In later versions of Windows this setting can be found in display settings, in older versions of Windows this was often configured in GPU control panel for the card (like the nVidia control panel).
