The joystick on the front of the unit isn’t to move the masking. The joystick is to help offset the whole projector image throw when your projector isn’t mounted center of projector screen.
Thanks for the clarification. Either way, that is the coarse adjustment for orienting the angle of the "cone" of light coming out of the PJ.
Glad you posted the other recs and your guide as well.
... -- you have to have the projector actually be mounted lower than the top of the projection screen to use it properly. That's in the manual
Can you point to where that is in the manual? I don't see any mention of the top of the screen and PJ height in the manual that I have (English version). IMHO, the manual is confusing to begin with on this subject by virtue of how the information is conveyed, and its measurements for the portion we're discussing are misleading and incorrect. Panasonic does not explain the process properly, based on my interpretation of their manual. Perhaps I'm the one with the interpretation issue, but I don't think so given the fact this seems to be a common problem that AE8000 users encounter.
Allow me to illustrate. First, the manual's guidance on the height of the projector is relative to the bottom of the screen. So, if you are following the manual's guidance one needs to start the measuring there (versus the top which is obviously the concern of most people if ceiling mounting or otherwise trying to shoot the image over people's heads).
I'll give you an example. Let's say you have a 150" diagonal screen and you want to setup the AE8000 for dual duty 16:9 and 2.35:1, and use its Lens Memory feature for auto-zooming. Page 22 of the English manual I have shows several pictures at the top of the screen designed to illustrate how screens are measured and labels the measurements used in subsequent tables. The manual indicates the calculated vertical height range of the placement of the PJ is relative to the bottom edge of the screen.
In my example scenario, you have a 150" diagonal 2.35:1 screen. Therefore, its image area will be ~138" wide and ~59" tall. So, following Panasonic's manual and looking at the line for 150" screen, I see the range of positioning the PJ's lens relative to the bottom of the screen (chart on page 23) is -0.75 to +2.24 meters. So, let's convert those measurements to the same playing field. Converting the 59" height to cm, I get 150 cm. Since 2.24 m = 224 cm, according to the manual, I could position the center of my PJ lens as high as 74 cm above the top of the screen (224 - 150 = 74). That's 29". Clearly - based on experience - far from reality.
Personally... I was quite disappointed and annoyed with Panasonic over this. When I researched this PJ before purchase, I determined I could mount it higher than was actually possible due to the aforementioned characteristics of the PJ, as indicated in the manual. I did my homework, and was subsequently rewarded with disappointment - thanks to Panasonic's egregious error. I was in the same boat as the OP of this discussion. Anyone who hasn't run into this problem and is using the Lens Memory / dual display size feature is just plain lucky as far as I can tell. The manual seems (to me) a useless resource in this regard.
Quite frankly, it's so bad that folks should have had the right to return the PJ over this issue as it would have been a deal breaker for some, no doubt. Moot point at this time, but I'm just sayin'.
Am I mis-reading Panasonic's manual? Please enlighten me if I am, because the way my brain interprets their manual (and I've re-read it a number of times), it's wrong to the point of being a gross disservice to their customers. If I'm wrong, I'd like to know (and I'll stop bashing Panasonic, LoL).

(The only exception is an Anamorphic lens, but the money is probably better spent on a better projector).
I wouldn't say, "all." PJ's with native image displays that are not 1.78:1 do exist, though they are not the norm. An example: Barco Orion Cinemascope MKII
(native 2.37:1). Of course, not that many people want to spend nearly $30k on a 1080p PJ.
