Toperson YG330 Projector is not featured with auto focus adjustment, but unfortunatelly it does not support keystone correction.
You’ll need roughly 11-12 feet of space between the projector and the screen to get to 100″ and if you want that 100″ or whatever size image looking square, you’ll need to make the projector pointing straight on and not from much of an angle. Considerting it is a portable mini projector, it is not difficult for you to set it up in a good position. With a tripod mount you will get a pretty neat home theater. Or you could mout it to the ceilling then you won’t be bothered by placing the projector accurately everytime.
But it does do a pretty decent job for what it is. If you want something with a little better features, you may look for projectors that has keystone adjustment.
