As far as 30'' goes the need for AA depends ofc on the distance you are sitting from your screen. For example, with 23'' display with resolution of 1920x1080 a human with 20/20 vision can no longer tell the difference between AA and no AA at distance of ~70 cm. Ofc when you are sitting closer than "optimal" distance or have particularly keen eyesight you can get the benefit from AA. However, even then I suspect that anything over 2x or max 4x AA is mostly for e-peen. In the sense of "I run this game at MAX SETTINGS" regardless of being unable to visually see any difference between say 4x AA and 16x AA.
One of the problems when making high resolution displays is the number of defective pixels allowed per display. For example, 1920x1080 display with approx 2 megapixels allows up to 5 bright defective pixels by ISO standard. The number goes way up with increased resolution. Currently - bcos these displays are considered "high end" manufacturers go beyond ISO standard - for example the DELL UltraSharp series "Zero bright pixel" policy.
The human eye with 20/20 vision can be "maxed out" with resolution of approx 7600x5000 pixels covering the approx 120 degrees horizontally and whatever was the number vertically where people have 3D vision. Dont have the link at hand atm, but was looking into 3D vision a while ago (more specifically head up displays) and that was the number that I remember from that.
