I just got back from best buy hooked up my x1 projector after returning the one with the bad pixel and bad line and this one has a different problem. On the one I returned the picture would not move when i focused the picture, which I'm assuming was the way its supposed to work. But this one I just got when I try to focus, the picture moves around in a circle like i was moving the projector but the only thing I'm doing is spinning the focus knob. I'm guessing the lens isn't on straight. Anyone else with an x1 have this problem or know how to fix it. I guess I'm returning this one also. It doesn't move much but I'm gonna have a stationary screen and its gonna be a pain to have to move the projector every time I focus. When I use zoom knob it just makes the screen bigger or smaller and dosen't cause the weird movement. Don't they test these things before they sell them?
