A:Answer Tony,
From my experience with this reciever, it does not have a way to enlarge the image. It is simply passing the video from your source (i.e. cable box) to your projector. The projector is the one that will do the enlarging of the image to fill the screen. If you are finding the image is not filling up the wall or whatever the projector is aiming at, you need to move the projector back which will enlarge the picture. Hopefully you are able to move the projector back, but if not you are stuck with what you have.
The other question is no, it does not have a dynamic image enhancing thing like you are asking. The dynamic piece it does have is for sound only. Keep in mind this is a receiver for mostly sound not picture. Receiver/amplifers are mostly for enhancing sound. Again to enhance the picture, this would all come from the projector. Not to offend you, but you might want to look up the owner's manual online to see if it has ways to enhance the things you want on the projector.
