hi all,
my sony 1272 projector(non-isf'ed) is pretty far from my screen(more than 14ft back). thus i have to "size"(shrink) and "shift"(upwards) my picture to make it fit on my home made 16:9 screen. thus, the picuture is smaller and is on the lower half of the crt. the projetor is currently on top of a 4ft tall stereo rack that's behind my sofa. i'm in an apartment so ceiling mounting is not an option. i thought about floor mounting, but my setup is so that there would be very little walking space and some major furniture moving to deal with.
so far a major benefit of this set up is that even with a 480p signal, there are little to no scan lines since the pic is small. by the way, i'm using a skyworth dvd player via the vga out.
brightness is actually pretty good since i only watch movies at night. also, after i turned down the gain, i can still get a pretty bright picture at 40 brightness and 70 contrast. with the gain on factory defauts, my bright was 35 and 45 for contrast. better numbers for contrast and brightness but with the factory setting for gain, the picture looked hazy.
i took off the blue lens the other day and noticed that the 16:9 picture takes up exactly the lower half of the crt. fortunately no burns yet. i am concerned that this uneven phosphor wear will really messed up and shorten the life of my tubes. perhaps later on when i ceiling mount it i can set it so that it uses the upper half of the crt face.
what do you guys think? should i be worried?
thanks,
hiko
