Digital Projectors - Under $3,000 USD MSRP > AE100 16:9 mode is -/- 15% lumens?

Question: Do i miss something?

AE100 = 700 lumens 800x600, but when i use the 16:9 mode 848X480.
Isn't it only 595 lumens, because it must be blocking 15% of the light.
I hope i am wrong here, i need the lumens for a good 2.5 meter wide image

Btw when using 16:9 mode don't you get grey/black borders under and above the image on the screen?

I do not notice any light loss from the AE100 when projecting 16X9 material. Yes you have the gray bars when you project 2:35 and the bars are not there for 1:85 (my favorite) and 1:78.

Not true.... the AE100's full panel is 856x480 @ 700 lumen.

Showing 2.35:1 AR films uses 75% of the panel for 525 lumen.


By comparison a 1000 lumen XGA 4:3 projector running at 16:9 (1.77:1) outputs 750 lumen. XGA projector showing 2.35:1 AR films uses 56% of it's panel, for lumen of 560.

So a 700 lumen AE100 is equivalent to a 1000 lumen XGA projector in widescreen use.

You are right, i was confused by the term SVGA. Everywhere they say it uses a SVGA panel. SVGA is normally 800x600, it would be fairer if they had called it WVGA (it is 848x480 instead of 640x480).

I don't know, everywhere I see it is listed as WVGA. Who has it incorrectly?

I've seen it listed incorrectly as SVGA several times on stupid webshops. :)

On a 4:3-projector, although the amount of light from is decreased when running in 16:9 mode the brightness is still the same. What I mean is that the whites are still just as bright.

The same goes for a 16:9-projector (like the AE100) running in 4:3 mode with black bars on the sides.

Most places call it correct WVGA... it's definitely an error to call it SVGA.
