3d Vision with an 85Hz Projector
Hi- I just noticed today that my DLP projector- the HP VP6120, supports 85Hz in 1024 x 768 mode. I though that might be good enough to support 3d and searched the net and this forum to find that many people had gotten good results with 85 Hz. The post I saw required people to buy a special dongle that I don't think is being made any more. I was wondering if I can just buy the 3d vision kit and get it to work without this dongle or do I need the dongle to make it work? I can afford the 3d vision kit, but not the kit + a new projector. I would love to get this working on my old projector so help is appreciated!

Ok I went and bought the 3d vision kit since I saw a lot of people were having luck. I didn't really read carefully enough it seems. I guess nvidia stopped allowing 85hz monitors as they just link to their page when they can't detect it as 3d vision ready. I thought at least they would allow some kind of manual settings. It forces consumers to buy the projectors they promote. It seems to represent some type of antitrust issue but who am I to judge. Does anyone know a workaround for this or is Nvidia will allow manual settings in the future like with their old drivers? It seems unfair to folks who have Nvidia cards, motherboards, and now glasses. Really I think it would be a good segue for people before they upgrade to a 120Hz model.

At 85Hz it'd probably give you hoorendous eye strain and headaches, plus it'd look flickery and crap. I imagine so, anyway.
There's a reason it really should be 100Hz+

Yes 85Hz does work for DLP projectors and for some very well. In fact Nvidia's drivers used to allow for it before they apparently made a deal with manufacturers to shut older displays out. An extra $600+ is out of reach if I have to fork over $600+ for 3d Vision + 4 glasses. Come on Nvidia at least give your users an option to try it on their own systems, you don't have to support it. You are really burning your fans.

I also have a Infocus LP70+ that does 120Hz but Nvidia won't allow us to custom settings like in their older drivers to allow it. Is there any way to override this?

Can I do an EDID override to trick Nvidia's software into thinking its a 3d vision projector?

3D can work at 85Hz, I did it for a while with the old legacy Nvidia drivers. It is not the best quality, but you can live with it. Even 60Hz can work, although the quality is clearly low with obvious flicker. Anything less is unacceptable. However Nvidia does not allow this on their driver anymore. You can maybe work around this if you try really hard. The EDID over-ride will not work though, because your projector would need to support a compatible mode of a real 3D Vision projector (ie 120Hz). You could try disabling EDID altogether (by removing the pins on an extension cord) and then setting you projector as a generic plug n play display. This should allow you do select it as a generic CRT display in the Nvidia 3D Vision wizard, however if you cannot do at least 100Hz the driver might not allow you to select this setting. You can see how you would do this here (use the old instructions, in italic, on the bottom of the fist post):

Also, this is why it is important to read up on compatibility of products before you buy. Especially regarding 3D equipment, it is absolutely essential.

Thanks- I'm trying it now but encounter the problem where I go to enable 3d Vision and the screen to set it up defaults to 1600x1200 which none of my displays supports. Any suggestion for how to force the setup to not default to this large resolution? I tried right clicking and choosing 640x480 in windows but that doesn't seem to work.

When i tried many months ago, my old toshiba projector was seen as a Generic CRT using a vga cable, i think now if you use a dvi cable you need to cut off 2 pins, and your projector will be seen as CRT, then it will run @ 85hz

hi Remedy2 have you had any luck with this projector? im trying to get 3d vision working with a hp vp6110 which also supports 85hz but even though i have been able to run 1024x768 @ both 100hz and 120hz fine however i cannot seem to enable stereo or should i say see stereo! when i select this mode the projector also displays a message saying what resolution/hz it is in and also a specific mode number so i know its a dif mode to the others i.e 1024x768 @ 85hz

i used a hacked (pins removed) dvi to vga adpater and a modified acer 5630 projector inf, which changed the supported resolutions under windows....without which i could only select the 100hz modes when i deselect the hide modes this monitor cannot support checkbox.

howver the 3d vision wizard doesnt detect it as a compatible device but i am able to go through the wizard and set it up as a generic crt...it does also run at 100hz but i dont see a 3d image? if i trick the wizard by selecting the right answers i am able to go in the stereoscopic menu and play with the stereoscopic test and try differnet resolutions and hz's but i still dont see a 3d image...all i get is a wobbaly/flckery image which reduces if i reduce the depth setting?

im wondering wether my 10+m vga lead might be casuing sync issues so im going to try a shorter lead tonight.
