Screen door effect isn't only a matter of resolution, but also (and primarily) the physical construction of the display. Each pixel (or light emitting element) is discrete, surrounded by a non-light emitting border. Kinda like stacking multiple monitors, each with its own bezel, in an <a class="bbc_url" href="

If you increase the resolution with the current technology the effect will still be there, only the screen door mesh will be more fine. But it would take a ridiculous and impractical resolution to make it truly unnoticable when the display is stuck right there an inch away from you eye.
Imaging sensor (think digital cameras) manufacturers faced a similar issue only in reverse where the <a class="bbc_url" href="

They worked around it by first moving the wiring layer behind the light-sensitive photodiode (<a class="bbc_url" href="

At least that's what working a few years at an optical/electronics company has taught me.
My brother-in-law seems to be all over the VR idea, I remain somewhat sceptical. But when I have a chance I'll go visit him and evaluate what potential the current attempt at VR has for meeting and enjoying the waifus up close and personal.
