For example, a 65" high screen is typicall 153" wide. If I reduce my projection height to 64" (which is what I can fit), my viewable width is still 155.5")
Sorry if this has been covered earlier, but on the phone with Sony and me dealer trying to get it sorted out...
Thrang! It uses a standard 4K panel. Bite your cigar! Divide the 4096 horizontal pixels by the 2160 pixels and you get the standard 4k aspect ratio of 1.89. For native 4K source material this will fully light the Sony panel. Movies etc shot in higher aspect ratios will have horizontal black bars
Now 4 HD (UHD) projectors *coming this fall) and panels (already here) have only 3840 horizontal pixels while still having the full allotment of 2160 and having their panels in a 1.78 aspect ratio 3840 divided by 2160). Material shot in aspect ratios larger than this will have black bars on the top and bottom. You already know all this buy I couldn't resist.
Now there really is no standard aspect screen size. What aspect ratio screen one wants depends. Many choose 1.78 mainly because they think that is somehow the standard. there is no standard. That size is what HD TV is broadcast in and many blurays especially animations use that. But films are shot in many aspect ratios ranging with rare exception from 2.39 back to old day 1.33. hardly anything is shot in 2.35 but many think that aspect ratio is the standard for wide screen movies. they like most other times in their lives are wrong. I have made a carrier of being wrong, so no offense intended to anyone.
What I think is the best solutions to choosing an aspect ratio is to buy a screen which has them all. The idea being to project the shot image in its native aspect and to employ as much variable masking as needed to black out any white or gray screen material not used for that aspect ratio after zooming or stretching vertically and using a true 4K horizontal stretching lens. To me that means choosing a native aspect of 2.40 and using variable side masking to black out the sides from anything smaller than 2.40
Now we choose the weird ratios. 2.35, really weird but used by many who aren't weird. Go figure. That obviates the need for any variable side masking for wide screen movies. You just overscan a tiny bit fir aspects higher than 2.35 and employ non variable side masking to black out the sides tto make the screen from a non standard 2.35 to the native HD aspect of 1.78. But one can do whatever one wants. Some want the widest possible screen there room might fit. One might want the largest 1,78 image possible. There are lots of choices and customizing a screen aspect usually does not cost a lot extra.
But there is no right and there is no the most popular means its right. Its wrong and the only way you can make it less wrong is to employ variable masking and to start with a 2.40 screen.Edited by mark haflich - 5/28/13 at 10:32pm
