Upside Down glasses to have 3D effect Upside Down glasses with DLP projector at 85Mhz ?
Hello
With a DLP projector at 85Mhz, I must invert my glasses to have the 3D effect.
When the glasses are 'upside-down', so my left eye is looking by the right side of the glasses, and vice-versa.
It is very unconfortable.

Is there any trick to correct this issue?

(In the configuration panel, I must lie about what I see in left and right eye, otherwise the tool return me an error.)

I have the same setup as you and suffer from exactly the same problem. As a result my expensive 3D Vision glasses are only ever taken out of their bag when I have friends round playing multiplayer games in 3D. The rest of the time I'm forced to use my old E-Dimensional or Another Eye glasses as they both have an option to invert the eye sync so I can wear them the right way up. Their ability to resync also means I experience less ghosting with them than I do with the nVidia ones (which is ridiculous as the nVidia glasses are much higher quality).

The really frustrating thing is that the old nVidia 3D stereoscopic drivers (from before the launch of 3d Vision) actually had an option that enabled you to adjust the sync with hotkeys but that capability was removed (along with several other useful features, apparently in a deeply misguided effort to make the control panel simpler).

The issue has been raised in several threads here over the last year and I (and others) have contacted customer support directly about it too but just received generic brush-offs. It's not just projector users who are affected by sync problems either -some owners of the bundled monitors, CRTs and even DLP TVs have reported strips at the top or bottom of their screens having reversed 3D as a result of their glasses shuttering too late or too early.

There is one ray of hope, however -just recently [url="http://forums.nvidia.com/index.php?showtopic=150018&hl=timing"]someone contacted customer support about ghosting[/url] and was told they're working on a new driver which should help reduce it. This [i]may[/i] mean that they're finally going to re-enable user controlled glasses timing adjustment which will be a huge improvement for projector users like us (and for all those others suffering from sync discrepancies between their monitors and their glasses). Until then your only options are to continue wearing your glasses upside down or to build a hardware delay circuit.
Cheers,

Ive been playing this ghosting game for a long while now, and it always came down (in my mind) to being able to adjust the sync delay.

I have the Viewsonic PJD6221 (not 6211) which at this point remains unsupported (green ghosting) and upside down glasses.

Without control of the sync, you are screwed. I had to buy the Next Step Solutions Sync Delay Box off of another user in this forum. It works fantastic. In fact, it seems I can now play games at 1280x1024 at 85hz. Not native rez mind you, but it does make the game look that much better. I had assumed earlier that the Nvidia glasses were just not as good as the Edimensionals, but I was wrong, they can actually produce zero ghosted 3D and arent as dark.

All I can say is hunt down this sync delay unit, cuz thats all I could do to FINALLY get complete zero ghosting and ability to play with glasses right side up. Now all is well for me in 3D land. Plus my Edimensionals still work as well, so i have more glasses for more people.

Nvidia needs to get some sort of sync delay slider in the control panel (dont know if this is possible or not).
