When projecting an image from my radeon 9000 using my new sanyo plv-z1 the the top of the image is narrower than the bottom like a trapezium but not by much. I can see that the projector is outputing a perfect rectangle as I can see the excess light where the pc image should be. Is there anything I can do to change this. I am running Win 98 if it matters. Also any tips on what setting to use in powerstrip would be apreciated.
