SInce I'm behind the idea for Super Wide feature, let me explain it here.
I like Constant Height Theater concept, I have a 16x9 lens with my HD81 in my home. I had a H77 with a Panamorph setup in my old apartment 3years ago. But additional 16x9 lens may not be affordable by many. So that's where Super Wide idea was from, how do we enjoy a constant height theater without the cost? Or a poor-man's solution to CIH?
Of course, one way is like AE3000, using >1.3x zoom and power zoom/focus. But how about for projector without power zoom/focus or >1.3x zoom? That's where Super Wide came from.
Super Wide works like this (using with a 2.0:1 screen):
Position projector with Super Wide to fit the side of the image to the 2.0:1 screen, and center the image/screen.
For 16x9 1.85:1 content, HD8200 will mask top an bottom area to make 2.0:1 image, this still preserves the "safe area" of the image. 5.5% of the image on the top and bottom are masked. So a 1920x1080 image is shown as 1920x960, no scaling, just masking off 60 pixels on top and bottom, respectively.
For 2.35:1 content, HD8200 enlarge the image so that the height of the image fill the 2.0:1 screen area, while cropping on the side. Again, most of the saft area are preserved. So a 1920x817 is first scaled up to 2256x960, then crop the side to show 1920x960 2.0:1, the cropping is 7% on each side, preserving most of the safe area. In this way,we use slightly more vertical resolution for the 1080p 2.35 content, from 817 to 960, 17.5% more pixels.
There you have it, with 5% to 7% masking/cropping, user get a constant height image of 2.0:1, actually constant 2.0:1 image.
It works best with a 2.0:1 screen with black border.
Of course, cropping/masking may not be for everyone's taste, so we default at Off, user can enable it, the projector will detect the content and automatically do the right conversion.
If user don't like it, just keep it at default. For user who can accept mask/cropping based on "safe area" concept, then one can enjoy "free" consant image height with a 2.0 wide aspect ratio.
Sorry if the user manual does not explain it well. But this is the idea behind the Super Wide, which was first introduced on HD65 (to offer more feature/options for low cost 720p), then onto HD80 and now HD82.
En gros ça veut dire :
- il faut faire un écran au format 2.0:1 au lieu de 16/9 ou 2.35:1
- le 16/9 est alors affiché simplement avec un masquage de 60 pixels en haut et en bas (soit 11,1% de l'image non affichée),
- le 2.35:1 est quant à lui d'abord upscalé de 1920x817 en 2256x960 puis affiché avec un masquage de 168 pixels à gauche et à droite (soit 14,9% de l'image non affichée).
- l'image dans les deux cas remplis donc bien la totalité de l'écran 2.0:1 et il n'y a pas de bords noirs ni en 16/9, ni en 2.35:1
Les avantages :
- pas de bandes noires ni en 2.35:1 ni en 16/9,
- pas de déformation de l'image.
L'inconvénient :
- on rogne presque 15% de l'image sur un film en 2.35:1 et plus de 11% sur un film en 16/9 !!! A mon sens c'est énorme !

j'éspére que celui-ci régléra tout ses problémes...dommage 
vivement un CR
