Hi, i recently finished my projector using a proxima ovation 810 and i almost couldnt be happier with the results except that every time i turn it on the picture is in a bottom corner and i have to move it up and to the side and i also need to increase the contrast everytime i turn it on. those two things are easily fixable but one thing that i dont get is i can only get a 3:3 perfect square picture in the middle of the lcd, how do i stretch it out over the whole thing?
