I have a Grayhawk 100" 16x9 fixed wall screen. The top of the screen is currently 27" from the 9 ft. ceiling. I just got a DWIN Transvision and am expecting a Panamorph soon. I know that with a 16x9 image the DWIN can move the image up and down within the 4x3 panel. However, with the Panamorph will I loose this capability because the image is sent to the entire panel? In other words, must I use the 4x3 screen offset to determine the image offset as the DWIN manual states? This would be 6 to 8 inches instead of about 22.5in for 16x9 offset. If so I would need to mount the DWIN lower from the ceiling or raise the screen.

Yes you lose the ability to shift the image because the whole idea is to use the whole panel for the 1:78 picture. The 1:78 picture is stretched to the 1:33 panel so you no longer will be able to shift unless you distort or cut part of the picture .

with the Transvision you use the 1:33 offset for setup of the screen to projector relationship, this 1:33 minimum will be your downwall (measurement of 6").


You also need to set your screen to 16:9A as this mode has more stretch/compress for the Panamorph.

This effects all 1:33 projectors using the Panamorph.



If you use a Panamorph 2 (2:35 lens) you will increase the vertical height to push the black bars off the 1:33 panel.

I will be using both Panny1 and Panny2 on the Transvision so I need a new screen to get my picture centered in relationship to both these lenses which will use the whole panel on 1:33, 1:78 and 2:35.

I can not wait.
