LOL so there are two rings? I didn't even realize, now I feel dumb. Here I am thinking the only way to adjust it is placement of the projector.
Gonna check it out when I get home
Loving the projector by the way even in my small bedroom, it could be better with TV but it's awesome with movies. Watched MIB3 on it
Wish I had bluray.
Ah you really need to find some HD sources if you enjoy the projector.
That doesn't mean you can't enjoy it with DVD's etc. however the bigger you make the image the more you start to notice the sub-HD content.
Just a heads up so when you go home and and increase the size, if it looks a bit "soft" that would be the primary reason.
