what I've read good human vision can resolve about 0.3 arc minutes per
pixel so the difference between 1080p and 720p is definitely noticeable
at that distance.<br>

</div>At 3m I can tell the difference on a 24" screen, so it all depends how<br>
much you notice this, and how good the source material is.<br>
