Projector(NEC PA550W) screen flickers continuously when connected to Windows11 laptop

Copper Contributor

Hi, When I connect my windows 11 laptop HDMI port to a NEC PA550W projector HDMI port, the projector screen continuously flickers & flashes. However works perfectly fine on a windows 10 laptop. I have tried changing resolution to match on both the laptops and additionally tried all available resolutions on the windows11 laptop, but the same flickering result on the projector screen. The NEC projector team can't find a fault on the projector because it works Ok on a windows10 laptop. I have tried with other windows11 laptop, but end up with the same projector screen flickering result. Any advice please?
