Capturing nintendo switch - only a corner of switch's output is captured

[ResetButton]

I connected the hdmi to a capture card, hdmi to my laptop and usb to my laptop. When I add the source into OBS I only see a corner of the switch screen. I have tried Transform fit to screen etc. If i change the output size on the source to custom it disappears. Dragging and resizing just shows that part of the switch's screen larger. It doesn't show the missing parts
