The bezel on the DUDU LCD panel is black. I don't care about the border line on the curved black screen, but in bright themes, I think the system can be changed more luxurious if the line of the liquid crystal exclusion is rounded rather than perpendicular. There is also a separate app on MacBook that connects the normal monitor and makes the border area round.
I'm talking about the curvature treatment of the bezel on the border of the system, not the navigation menu on the screen you showed me.
