here are my results of the stretching issue of my LG HW301G, anyone with more knowledge of aspect ratios math are welcome to comment and try to put this issue to rest
I have a 52x83 inch screen in the 16:10 format, that's 97" diagonal @ 10.5 feet
which in 16:9 mode should be 47x83 inches according to projector central calculator
in 2.39:1 mode it should be 35x83 according to projector calculator
Playing my "Pelham 123" bluray movie, which is supposed to be 2.40:1 ratio, I measured my image at 38x83 with bluray player set at 16:9 normal, and projector at "just scan"
so, that's a 3" inch difference, again the calculator says 2.39:1, but movie is 2.40:1 maybe that accounts for the 3" inches? anyone have any thoughts....btw, I tried the steps on the youtube video link above and "just scan" is what you end up when you used the zoom settings you see in the video.
one final thing....playing a movie that is recorded in 1.85:1 aspect ratio "edward acissorhands" bluray, the image is 50x83 inches, so it's a 3" strech from what a 47x84 (16:9) should measure...sooooo, it looks like this projector stretches everything by 3" inches on a 97" diagonal screen via HDMI.
