I have been fooling around with some creative ways to utilize the masking border built into the Dalite Model B pulldown. When fully extended, the ratio of the screen is 16X9. I notice when the screen is rolled back up into its casing, it locks in at certain increments. I was estatic when it stopped rolling exactly at the 2.35:1 point. The on-screen image (The Rock CC) was perfectly masked! Does anyone else use this technique? Was the screen designed to stop at this point specifically for 2.35:1? My only problem now is the upper black masking bar disappears. Perhaps I can cut a stip of masking material identical to the size of the border on the Dalite? How could I affix this strip to the the sceen without disabling the rollup capabilities of the Model B that I am currently enjoying? Thanks for any suggestions or comments... You guys are the best!
