is there a way to disable light boost completely ?
  1 / 2    
can it be disabled from the drivers or from the registry ...anywhere ?

If it's a brightness issue that recently manifested in a driver update, the driver forums state that the latest driver fixes the issue. https://forums.geforce.com/default/topic/1002975/geforce-drivers/always-full-uncontrollable-brightness-after-driver-381-65-update/ Check Blurbusters for registry entries and hacks.

Then get rid of it? What makes you think that you even have it? AFAIK, the GeoBox does not support it, I don't think it even could.

I sometimes feel gamma is not correct and yet the calibration image in specific game looks ok. Like for Example calibration image shows ok brightness but image looks washed out, and one needs turn down the gamma from the game Down below clip to get good image. With some games not all.

Actually i use mainly win7. I have not had this kind of thoughts for long time. As i last noticed this with far cry 4, from 60hz 2D switch to 120hz 3d and the gamma Was really different. Last night i tried crysis3 after long time with monitor and today with projectors. The same scene i Was left off with monitor looked really Different than from what remembered last night, the gamma Was much more bright with same setting. That just drove me to think could there be Something going on with the light boost but i don't know maby it Was just summ of many.

I used quickgamma previously, it worked ok, it sometimes seemed to hang and not change back. What sucked was no hot key support. A quick check found https://sourceforge.net/projects/gamminator/ You might try it. HDFury made an in-line gamma device for projectors, but it was VGA only, if I recall correctly. Gamma Doctor, I think ? Edit: it was Gamma-X https://www.hdfury.com/shop/discontinued-devices/gamma-x/

Are you seeing this 'light boost' with the glasses on or off? If they're off then that's perfectly normal because you're seeing both eyes at once... which would wash out or seem to brighten the display... Also if you're using DLP-Link then there's the extra white 'flashes' that are needed to sync the glasses... that's also display specific and separate from the signal being sent by the Drivers.

His projectors are ran in 2D mode. 3D projectors are not even required for Dual Passive. So it's not the DLP Link flash, but great suggestion.

No i don´t see any lightboost menus or direct indication that it is on. i just made an assumption could it be on as the gamme changed and colors looked a little washed out.

The only other thing to check is your dynamic color range. Or perhaps your PJ's bulbs are dimming/going out?

That´s they beuty of passive. no flicker and as bright picture as in 2D. i based my intial question on this thought, i was thinking the nvidias lightboost tehcnology would do some sort of gamma alteration on the output but it was just a ques as i have not read into how lightboost actually works. And as geobox is not a certified Nvidia display device but just merely a demultiplexer with capability to recieve frame squental 3d i thought "maby what if" the lightboost is just gamma change in code and it´s always active and as geobox is not certified equipment there is no settings and monitors for lightboos but it just would be on and the gamma would be altered. i just find my self often going well below the gamma defined by a calibration image ingames so i started thinking. but if the lightboost technology does not do anything software wise to the games gamma then it can´t be that but something else. And there is so many affecting factors in my system that maby the "problem" is just cause of many things. i have normal color space adjustment on projectors, i have black level set on my projectors (IRE 0/3.75/7.5v) and i have gamme settings. and the polarizers darken the image some. so it just might be a sum on many things. maby im just mad :D
