Virtual reality head-mounted displays require high pixel density because the screen is very close to the user's eyes. An HMD with low pixel density can cause blurring of words and objects, reduction of immersion and elimination of presence. In VR PPI is just as important if not more important than resolution.
As pixel density increases, lower persistence is needed to avoid blurring.
