When I installed my projector I made sure it was level. I suppose I checked the wall at some point but not with a long enough level to span the entire height of the wall.

It looks fine and I havent noticed any keystone problems, but I went to build a frame for the screen I noticed the top half of the image didnt fill the frame! There was a .5" gap on both sides at the top and it filled the frame at the bottom. I guess the top of the wall is closer to the projector than the bottom.

On a 120" screen with the naked eye you dont really notice this amount of keystone, but as soon as I put a black velvet frame around it it became evident.
Will I encounter any problems tilting the projector (up I suppose) until the image lines up square on the wall without any keystone? I assume the small amount that it is off is just a minor adjustment on the mount. Unfortunatly the mount is 15 feet up in the air so I have to borrow my neighbors ladder to get up there!

Thanks for any suggestions

You'll also have to lower the projector mount unless you have plenty of room at the top of the screen or above the screen and can move the screen up.

Or maybe move the bottom of the screen away from the wall to make it closer to the projector, although how well that'd work depends on how it's constructed.

Should be fine, as long as you have enough vertical shift to compensate - avoid keystone if at all possible.
