what's DK2's "real" resolution? How much pixels discarded?

I must point out that light should always refract onto the retina(macula lutea), and not on the back of a persons lens...
So those schematics are a bit off. Not that I'm contributing to the topic... Sorry folks!

If this was addressed at my schema, yes I know that. I've simply not traced the rays from the center of projection (nodal point) to the retina, like it's done here for example :

If hellary's method is good and the DK2 uses approx. 85% of it's screen, the resolution per eye is probably closer to 888x999 pixels per eye if you keep the same 8:9 ratio as 960x1080. It would depend on which lenses you use to if the number would be higher or lower.

If the area of the screen that is used is limited by the lenses than the section of the screen that is visible is circular as the lenses are circular. If the warp is cropping the screen more than necessary then it should be modified, to work with a larger wider angle render.

A simple way to measure this by someone who has either DK's would be to set it as a monitor of the native resolution then open up Paint Brush on it and use the paint brush to trace the edge of the viewing area (probably easiest to do this while closing the oposite eye). Press the print screen button to make a screen capture then upload the image to this thread so we can see how much it differs between different people who are short sighted or long sighted..
