a common mis-conception, totally wrong.
ovf resolution is limited to how fine the pattern is in the ground glass screen; most of the screen needs a coarser low-resolution pattern, or you wouldn't be able to see the focus effect coming into clarity as you turn the focusing ring on the lens.
af dslrs negate that, they need a finer grind in the screen pattern, because that makes it brighter... however it wrecks the mf capability, because oof looks similar to in-focus areas, so people resort to swapping out the stupid af focusing screen for a low-resolution coarse screen... been there done that with pentax, it sucked.
with evf you also get magnification, which is the ultimate in high-resolution, no ovf can touch that.
