There have been a lot of interesting conversations about ppd.
Multiple headsets with similar or the exact same resolutions are all claiming 35ppd with different FOV values. What we saw recently with the BSB was the first graphical representation showing how this is accomplished in the image below. They have a linear progression dropping away from the center of the lense sort of like fixed foveated rendering.
Some difference is due to culling pixels on the display, but there is also very distinct mapping of more pixels to the center of the lens.
The Somnium and the Crystal both have the exact same resolution displays and both claim 35ppd, but the Somnium has a much larger FOV. That means that they have different resolution densities across the lens not exactly like that below, but something that makes sure things are sharp in the center and then dithers out to the sides.
