This has the potential for a flame war which of course every good salesman should avoid at all costs. Being an unemployed salesman and owning a 1000ES I however can fearlessly enter the flay.
Fitst, Tthere is no patent lie.
As for displaying anamorphic material, the Sony specifications laud the zoom features and zoom memory but do say there is provision (anamorphic stretch) for using an anamorphic lens. There is no specification for what input resolution one can vertically stretch, the manual is silent.
I never really thought about ever using this feature which offers two different streches (1.24 or 1.24 and 1.33 depending on whether the chip is used at its native 1.89 width (4096 x 2160) or at 1.78 (3840 x 2160). The machine is brighter than the average projector, has more pixels displayed than I can even visualize and I thought if I ever move to where I could use a wide screen, I would just zoom. A true 1.24 anamorphic with 4K resolution is extremely expensive and given the pluses and minuses I just can't see the reason for using an anamorphic instead of zooming, but whatever.
There are really no 4K sources available yet with rare exception. At first blush, I would have assumed that the vertical stretch would work at any input resolution. But thinking about it and how RC works, I would have concluded that it won't work at 4HD or 4K inputs. Scaling at 4K is a beast and it requires a hugh amount of computational power. Scaling at 1080p requires quite a bit and that's why many cheap prpjectors don't include anamorphic stretch. But at 4K you need at least 32 slide rules and lots of slide rule grease. I do see how a consumer might have thought the machine would scale but thinking about it as an industry pro I would have concluded it wouldn't. I think it was just an oversight by Sony not clearly specifying at what resolutions it would work. Given no 4K sources available and the advertising push for zooming and zoom memory, no one thought about it.
In any event, there will be a video processor by Lumagen coming out some day that will do the required scale if anyone should need it. One will just have to suffer zooming until then. Hardly a a big thing.
There are really no alternatives to the Sony at this point and I personally think it would be silly to reject purchasing it because it lacked the ability to do vertical stretch at 4K.
