This may be related to pixels per inch. What is the pixel resolution of your headphones? How many pixels does the instrument occupy in the whole field of view? Are the pixels occupied by the instrument enough to display clear and sharp instrument graphics? I’m sure that if the field of view of PIMAX 8K PLUS is reduced to 100 degrees, the instrument will become very clear. But is it technically feasible at present?
My earphone is REVER G2, so I can only see the big elements on the instrument clearly, but if it is too small, it won’t work.
