A solution to reduce ghosting
Hello, I´m going to explain the better I can with my poor english. I have been testing with my Nvidia 3d vision glasses and Samsung 2233rz monitor, and I have discover that I have two problems with ghosting:

1st -> I have ghosting in the up and down zone of the monitor and it is impossible to solve moving the head respect the monitor.

2nd -> I have ghosting horinzontally in all the screen and with only a little horizontal movement of my head this ghosting increases more or decreased. It is not as apreciated as 1nd ghosting, but if you see a contrast scene it will be crearly appreciated.

I´m goint to write about 2nd because it is the solution I have found. In my glasses it is NOT possible to block 2nd ghosting totally with BOTH eyes at the same time (it is perefectlly possible with one of them or the other separatelly) because I think the polarised lenses are not aligned properly in the glasses and when one of them is aligned perpendiculaty to the monitor other is not. I suspect that a possibility is that the manufacturer has mount the lenses in the reverse orientation by error, bucause if I put them of the reverse in my face I can block properly both eyes at the same time (but of course my ears do not support the sideburns). If you see the plastic of the glasses, the two lenses do not form 180º with the vertex in the nose, they are with aproximatelly 170º, and this little difference of 20º error seem to be very important to block properly the lights. If I put the glasses normally in my head and I approach to the monitor I apreciate the 2nd ghosting increases, and if I go away it decreases.

I do not know if it is only an isolated problem in my glases because an error in the assembly, or it is a common problem. I bough my glasses aproximatelly 9 months ago. I would want to know if it is possible to change the glasses if this is the problem. Maybe a lot of people with this problem and do not detect it because it is easy to think that it is “normal” to have ghosting (but it has no sense if only putting them of the reverse the ghosting dissapear.

I think it is not only my problem, maybe a desing problem of these glasses. You can observe what I say just opening the Stereoscopic test in the Nvidia Control Panel. If my glasses are not wrong, you will see a little ghosting, apreciated in the sides if you have the head well positioned and centered, and if you turn a little the head you will apreciate increase of ghosting in one eye and less in the other (just the difference of the blocking polarisation angle). Now quit the glasses from your face and reverse putting the sideburns pointing at the monitor (using the same lens than before in each eye, of course), and if it is like me you will see the previous ghosting dissapear, and also you can turn the head more and still no ghosting.

This thing makes me to think that Nvidia has sacrificed quality of viewed and functionality in in exchange for obtaining a certain aesthetics. Please, report if this happend also to you, to be sure I have not a defective product.

Just tested this myself and I'd have to say your glasses are somehow defective. I notice no difference at all between the two methods of 'using' the glasses, and tbh, I really don't see any ghosting at all with the stereoscopic Nvidia logo test in the first place.

Are you using Samsung 2233rz monitor?... see that I do not refer to a big ghosting, is little, but with minumum turn of the head increases and maybe a problem.

there is no way to absolute remove ghosting coz goggle's matrix did not become abolutely black and still allow some light to go through

Yes, but if I use googles in reverse I see less ghosting. It has no sense.
