I'm having problems squaring up my RS-20 on my screen. Attached is a sketch showing how the image looks on the screen.
The PJ is sitting on a shelf about 10" above the top of the screen. I've just about max'd out my vertical lens adjustment. I can slide the PJ fore and aft and laterally left or right on the shelf. Or I can yaw the projector. I can also adjust the individual feet up or down slightly. Any suggestions on how to attack the problem? I want the image to be perfect. Thanks!
