"This means you can have that 201-inch display fixed in place while playing on the PS5 for example and allowing you to look around the space, or look away, without the screen moving with you."
i have nreal light too, for around $400 its really good.
there is a community made api that can access glasses head tracking data, some made their own multi monitor app demos too,
hope official one gets better later on too
edit; spacetop is using nreal light (6dof)
