I?ve got an old Sony 1041Q and I?m using it with an 120? screen, but typically set it to use only 100? on a 4:3 aspect ratio picture. Wanting a larger image on 16:9 material to fill the full 96? width of the screen, experimenting with the pots I realized I could adjust the Green ?main-v-size? and Green ?main-h-size? pots and widen the image to fill the horizontal (and increase the vertical to maintain proper ratio of the now widened picture).
To help in going back and forth I put some masking tape on the sides to be a good vertical queue to increase the vertical size when I expand the 16x9 image to fill the maximum screen width (and use bottom ones do the same when I bring the vertical back down and have to now narrow the horizontal image to get a proportioned 4:3 back).
Getting tired of opening the projector each time to adjust the pots I drilled two holes over exactly where the pots were and then experimented with some makeshift extensions and knobs to allow me to control the pots while the cover was on (couldn?t find anything pre made in radio Shack and other catalogs).
Eventually I did it using the barrel from a BIC pen as an extension (which after being cut to the proper length, just fit over the screw pot (loose when uncut, but after cutting the end got narrower from the knife and with one or two reams from the point of the knife fit just right, slipping over and gripping the edge of the pot screw). I trimmed the barrel of the pen at the surface of the closed lid and then found that the top of another type of stick pen (a Sanford SAGA) fit right into the open barrel of the BIC and formed a good knob extending from the lid. Now without screwing too hard I can adjust the pots from the outside.
Now here is my question: I read in earlier posts that when playing an anomorphic wide screen DVD I can actually ?squeeze down ? the image and get a less a visible line structure. To use this feature/benefit what do I set my Pioneer 505 DVD player?s aspect ratio to: Pan and Scan, Wide, or Letter Box?
My original setting was Pan and Scan. In that mode when my projector screen size was adjusted to 4:3 and I played a 16:9 movie, the image was correctly proportioned but smaller vertically inside the 4:3 screen. This was when I?d adjust the pots to widen and heighten the image. I note that if I set the DVD player to ?Wide? and watch a 16:9 movie, the unadjusted 4:3 projector setting results in a picture which needs to be lowered (people appear too thin). By doing this am I achieving the goal of "crunching down the lines"? Is this then the best setting for the DVD player?
