Hello!

I recently bought myself a Nvidia 670 and a Asus VG278H monitor with integrated IR-emitter and 3D vision 2 glasses. It works so far, but in game scenes with high contrasts, there is unfortunately crosstalk.

So I would like to adjust the open/close-timing of my glasses, to eliminate the crosstalk. Is there a way to do that?

And, sorry for the beginners question, is the timing controlled by the Nvidia driver anyway, or it is solid coded in the monitor-integrated emitter?


Greetings from Germany, and sorry for grammar errors.

Have you tried turning the contrast down to 0 on the monitor? That may help.

That's changing only a little on the crosstalk. It's still there.

It's surely a timing issue. I don't think it can be fixed just by making the image darker.

Surprised, I thought 3D Vision 2 was supposed to fix some of the cross-talk.

Though, as far as I know, the timing of the glasses is not a user-configurable setting. Anyway, if there was such an easy fix I imagine Nvidia would have done it already.

No, dosn't work that easy. The timing is adjusted in the nvTimings.ini which is part of the driver on a per monitor basis. This is, however, no useful information unless you manage to decrypt the values. I think nvidia has tried their best to reduce the brightness loss with light boost in 3Dvision 2, you can try to disable that feature in the monitor. Your complaint comes somewhat surprising, though, as Bloody from 3Dvision blog had attested this monitor one of the better ghosting performances...

I could try to experiment with the values. I have time...
I deleted the three lines for my monitor in nvtimings.ini, and rebootet. But everything worked like before. Maybe the driver needs that file only at installation time. So I don't know, were the values really are, which I have to change. I'm doomed...

Reducing lightboost in the monitor changes only the brightness, not the glasses timing.

Just to show you the crosstalk, I made a photo of "Limbo". That game is complete in black/white. So it has very hard contrasts, and the crosstalk is very disturbing. In other games and movies it's not that bad.
Look at the guy on the rope. (klick to enlarge)

On my windows 7 Ultimate x64, i found the timing adjustments at:
HKEY_LOCAL_MACHINE/Wow6432Node/NVIDIA Corporation/Global/Stereo3D
GlassesSwitchDelay 0x00000000
I suppose you can search the registry for that entry
Note too, in that key are the delay timing settings (effective when GlassesSwitchDelay is 0x00000001)
I believe these settings will add time before exposure and minus duration of exposure
A more brief of an exposure will help reduce visible cross-talk during frame switching, caused by slow pixel response timing (common on older and/or larger displays, perticularly LCDs)

You can change glasses timing with the RF solution from 3D-VIP/Monstervision/Optoma/whoever. The setup would be something like nVidia emitter->IR receiver->RF emitter->yet-another pair of glasses.
