Right now the odds on achieving world peace are lower than the odds on such a screen being created. Sorry if I am too optimistic.

Its looking good, but not for the Money it cost !


IMO

Gosh. How about they use adaptive optics to deform a high gain screen in response to your head position, similar to astro telescopes?

Not terribly cost effective, but easier than world peace. My most promising ideas on that front involve things like meteors and tidal waves.

After all, this is the $3,000 and up forum. This falls under "and up."

Hardware Update to 1100ES can change Gamut response?

Hi to all,
In the past years I've calibrated 4/5 Sony VPL-VW1000 and always the projector in REC.709 preset (by default) reproduce colors near refs.
The DCI mode reproduced a widest gamut but with a massive loss of light force.

In the past days I'm turned back to recalibrate one of those Sonys.
I've calibrated this unit one year ago when it was band new and gived the usual good results.

Yesterday this machine has some strange response, it has colors collapsed (desaturated) down into Rec.709 space ... specially Blu and Green if I remind well.
Also If I switch to DCI presets colors saturate not a lot to do a perfect Rec.709 calibration.
This is clearly visible also with the human eye.

I've checked this also connecting directly Oppo to the Projector and remains the same. I've changed also the HDMI cable but the problem persists.
I'm pretty shure that the problem is in the projector.

This unit has only two differences respect the first time I've calibrated it:
1) It is UPGRADED by Sony to the 1100ES;
2) It has a compatible UHP lamp (the original lamp was sostituied months ago) installed by the customer.

I'm thinking that this strange situation is reputable to the not original lamp but ...

Do you have some experience like this after the 1100ES upgrade? Obviously I'm talkin with those who has knowledge and meters to do affidable readings of the color response of the projector.....

Many thanks.

I do not remember this, sorry.
I've performed the calibration in the REFERENCE main preset (like before).
