Is the key to use full panel then zoom in your screen size to obtain max light output?
One of the keys to maximizing brightness and the key to maximizing display resolution is to force full width use of the panel and then full height use of the panel. To get the machine to put out max lumens one must set the Sony aspect to 2.35 Zoom and then the zoom must be set to its widest and not just what fills your screen at your set up. And center the chip image at lens center.
Switching the Sony aspect from Normal to 2.35 Zoom. This will stretch a 1.78 source frame (test frame 100 IRE full white etc) to full 1.89 panel width and will make the black bars on the side go away and be replaced by beautiful lit light producing pixels. I usually scream Aziz Light when I switch from Normal to 2.35 Zoom. Then zoom to full wide, set every other setting to maximize light out and there are many settings that will increase the light such as full lamp, 100 contrast, iris full open or auto full, RC on and I think set to 50/50 but I haven't played enough here. The machine won't be calibrated and will probably look horrible but we are attempting to get maximum light out to determine the accuracy of the Sony 2000 ANSI Lumens spec.
Now setting up for maximum brightness calibrated on your screen is another matter. And that depends on a variety of factors that can't not necessarily be maximized for all content aspect ratios. Basically one has to be set up at closest throw and be in 2.35 zoom and then use vertical electronic stretch, an anamorphic (1.24) and then say the hell with pincushioning because you are setting the anamorphic at close throw. Maximizing is difficult I think but I think your dealer together with your set up person would be able to accommodate your desire for the most calibrated light given your set up limitations assuming that is your objective. The best possible picture geometry wise might would not be the brightest. It should also be noted that we are all learning here, including dealers and set up people.
It should be noted that for aspect ratios below 1.89, the Sony can not put out maximum light without cropping out part of the vertical resolution.
It really takes some thought re living with a 1.89 panel in terms of 1.78 source frames with aspects on such frames ranging from 1.33 to say 2.40.
For my set up which uses a 110 inch 1.78 screen at a throw of around 14 ft, I will just set up a zoom memory for 1.78 full souce frames using the 1.78 test pattern 1.78 markers and set the Sony aspect for Normal. For wide screen material, I will set the Sony aspect to 2.35 zoom and a zoom memory using the 1.89 markers aligning with my screen edges, then I will masking the screen top and bottom using the same 2.35 positions I use for a 1.78 panel machine.
This is such a fun sport.
