Every row above is computed here from the stated resolution and the stated diagonal. With w and h in pixels and the diagonal in inches: PPI = sqrt(w^2 + h^2) / diagonal, which here is sqrt(2880^2 + 1800^2) / 14; pixel pitch = 25.4 mm / PPI; physical size = pixels / PPI, which is the full panel rectangle and not the usable area, so a screen with rounded corners or a notch has less usable area than the size shown; sharpness distance = 1 / (PPI x tan(1/60 degree)), the distance at which one pixel spans one arcminute for 20/20 vision; pixels per degree = 2 x distance x tan(0.5 degree) x PPI at the assumed viewing distance. Values are rounded to two decimals, and to one decimal for the pitch, the sizes in centimeters, the distances, and the pixels per degree.
