Surround resolutions aren't really "high resolution" in the sense that they have higher PPI or lower pixel size. The 6000 is spread across 5' of monitor space.

If that was crammed into a 30 or 40" display you'd be right that higher PPI reduces the need for AA. As it stands, 27" 25X14 panels are the best we have for that:
