Black bars appearing at the top and bottom / left and right of the projected image while the PC monitor displays correctly is a common issue when using Duplicate (Clone) display mode with an NVIDIA graphics card.
This occurs when the monitor and projector do not share the same native resolution or aspect ratio. In Duplicate mode, NVIDIA forces a common output resolution, which can result in letterboxing on one of the displays—typically the projector.
