The Dawes resolution limit establishes the closest angular distance at which two distinct point sources of light can be distinguished as separate by an optical system. It is dictated primarily by the diameter of the lens or aperture, with larger apertures resolving tighter details. While originally derived for astronomy, the principle dictates the sharpness and resolving power of high-end projection optics.

We're hitting the Dawes resolution limit on this projector lens, so those fine grid lines are always going to look a bit blurry at this distance.
