Hvis man har teknisk snilde kan den måske modificeres som de større modeller ?
Sakset fra andet forum ang. BenQ W9000:
I don't deserve the honor of having invented the following
modification, but I'm sure some of you will enjoy to have a description:
Before you open the box please make sure that lens shift is already set
to the uppermost position. Then while working through opening the box,
don't forget to unscrew the 2 very long "+"-type screws from the bottom
of the box (amongst all the other screws). Everything is a bit tricky,
but no rocket science, and if you never apply brute force you'll
finally find your way to open the box and proceed until you see what
pic 1 shows.
Next you remove the plastic cylinder/shield with the "PROJECTOR ZOOM
LENS ..." text on it, after removing the 4 very small screws holding
it. Then everything looks like pic 2. Next you remove the complete lens
section including the servo motors. It's done by removing 4 screws
holding it. The worst-to-come-by is the one where the screwdriver at
pic 2 points to. In order to reach it, you will find it necessary that
lens shift is set to the uppermost position, but this can only (easily)
be done when the projector is running, so don't forget to do it before
you dismantle your projector.
Once you have removed the 4 screws holding the complete lens section,
you can easily "unplug" it like is shown in pic 3. Now the modification
can be done: it's very simple, you just remove the rectangular piece of
black plastic shown exactly in the middle of pic 3. In order to do so,
you need to remove the small screw (near the upper edge) from it, and
then you can shift this plastic thing from the plastic cogwheel. Now
you're done and after rebuilding everything in the opposite order,
you're ready for big rewards:
While before the modification the zoom throw ratio (screen distance /
picture width) reached from 1.76:1 to 2.0:1, after it the throw ratio
yields a pleasant 1.48:1 to 2.0:1! Suddenly the W9000/10000 is no
longer such an extreme long throw machine.
You'll sure ask what's the price to pay for that. The absolutely
stunning answer is NONE! Or to be precise: a very very slight barrel
distortion shows when zooming the picture to the maximum size. But I
wouldn't have noticed it if I wouldn't have searched for something like
this. The picture sharpness is unchanged perfect over the whole picture
size.
You'll also get an additional icing on the cake: like with most
projectors the maximum brightness is achieved when zooming to the
maximum picture size. Because you now can zoom further, you get a 9%
lumens increase compared to using the unmodified PJ's maximum picture
size. With my 190 hours on the lamp, color temperature set to "warm"
(yielding app. 6'800K IIRC), iris fully open, and 250 W lamp setting I
get 1'100 lumens in the center of the image. If I would calculate
correctly compensating for the loss of light outside the center, I
estimate it would be app. 800..850 lumens. Not bad! I didn't measure
the loss of on/off contrast resulting from the extended zoom, but I
guess it's marginal.
Why does Benq not offer this nice flexibility as standard? Don't ask me for the mysteries of life...
I know some of you will be mumbling "if it sounds too good to be true, then it's not true". But trust me: this is the exception
Har kun taget billedet som viser hvad der skal fjernes:
Om BenQ W5000 har samme "nemme" løsning ved jeg ikke
.
BenQ, begrænset Throw?
Emne-funktioner
Din udregning ang. BenQ W5000 er fuldkommen korrekt. Prøv istedet at tage udgangspunkt i, hvor stort billede projektoren kan lave. Ca. 2,1 m. bredt på 4 m. throw ratio. Det svare til en faktor der hedder 1,9X. Så er spørgsmålet om du kan leve med det.

. Jeg har nu (naesten desvaerre) hoert saa meget godt om BenQ W5000, at jeg allerede har koebt den (in my dreams
).
. Jeg vil dog faa den forevist og selv vurdere om den ikke daekker mine "entrance" behov.
