they can if u give them side by side comparison or screenshots,
the cant, if they have to do it without and in real time movement.
if they know one has lower and one has a better Resolution, they can tell u witch one Looks better
but if u show them random footage without any hints, they cant tell u for sure "this is 720p, this is 900p, this is 1080p, this is 1080i" etc...
but this discussion is obsolet. because we know the Resolution of the game, even before we Play it.
