Nvidia 3Dvision on passive monitor/TV.

How to run Nvidia's own 3Dvision on a passive TV/monitor.

It is long known that 3Dvision was designed with active 3D in mind for the most part. Because of this Nvidia have not bothered to try very hard to make it work with passive screens and glasses. Only two monitors that are passive work with 3Dvision. One a Zalman, the other an Acer. Both are expensive. But what if you wanted to avoid Tridef and you had a passive screen?

Well, until now it was impossible. Tridef hates SLI so you can't use profiles and must run it in virtual 3d which is rubbish. However, with this method you can use a cheap LG D2342 and have Nvidia 3Dvision working, and here is how you do it.

First go here and download the .inf driver over rides.

http://3dvision-blog.com/7163-make-your-passive-3d-monitor-or-3d-hdtv-work-with-3d-vision/

Then go to My Computer and right click it. Click Properties

Then go to Device Manager.

Find your monitor and right click it and click Update Driver.

You will see this.

Click Browse my computer

You will then see this screen.

Click on Let me pick and then Have disk.

Browse for the folder with the extracted override infs in it and choose either. I used the Zalman one.

You will then get a warning telling you the driver is not certified. Like this.

Click on install this driver any way

Then right click on your desktop and select the Nvidia control panel. Go to the 3D part and set it as follows.

And then simply run the test.

And hey presto, 3dvision on any passive monitor or TV set !

To enable it in a game simply press CTRL and T. Job done.

Excellent. Does this work ok at 1080p and 60hz? I gave up with 3d vision and my 3dtv (active glasses). 24fps at 1080p was painful.

I don't know what hz it operates at but it does work very well.

Tridef does not work properly with SLI so I was suffering.

psychodil · 22 Apr 2012 at 13:34

You would definately notice if it ran at 24 or 30 hz like mine did. Wish id bought a passive set now :-(

I could run 3d at 60hz at 720p but looked horrible :-(

Anything about all active monitors being supported?

ALXAndy · 22 Apr 2012 at 14:14

I think most 120hz monitors would just work "out of the box" per se, but I could be wrong.

I know that some 120hz screens are labelled 3dvision so they may well need support at a driver level.

This has been a godsend though. Tridef does not support SLI and never has or will. Infact I am not even sure if it supports Crossfire properly yet because DDD (who make Tridef) were last seen palming it off onto AMD saying they need to support it. Tommy seems to be fine though so it should be in there now.

Problem of course is that Tridef is somewhat sponsored by AMD as their 3d mode of choice so you get no love being on Nvidia.

So that only leaves virtual 3d which is less than desirable. Objects like the melee weapons in Left 4 Dead 2 have a funny haze around the edges that kind of looks like the Alan Wake levels.

what i meant was if there was anything to convert a non 3d vision monitor that has it's own 3D 120hz to work with its own glasses to nvidia 3D

ALXAndy · 22 Apr 2012 at 14:36

3dvision supports every type of 3d. I didn't know that. So basically if you have a Nvidia gpu you could run anaglyph 3d with just a pair of those blue/red glasses.

Not sure how it would look mind as it never really worked for me.

Hi,
Some good info on this here,its abit more mature so has good info

Tridef does support sli im using it

Martini1991 · 22 Apr 2012 at 14:51

I've just been using anaglyth 3D with my old 60HZ 1080p monitor with 2 quid cyan/red glasses.

Don't have the money to get a 120HZ monitor and glasses

What 3d mode are you running though?

If I ran Tridef using profiles the game would stutter like crazy. Literally 5 FPS.

Virtual 3d mode sorted out the sluggishness, but did not look anywhere near as nice as true 3d. Plus I ended up with 1" bars down the left and right side of the monitor as the more you increased the depth the smaller the image became.

3dvision has sorted all of that out though and obviously does support SLI.

Hi,
I use interlaced\interleaved for all my 3d gaming and passive 3dtv's.
Some tridef games I've played have had issues like you mention,maybe try these games with af and aa turned off.

ALXAndy · 22 Apr 2012 at 16:15

Yeah I did try that (turning off AA) but the issue doesn't seem to be AA related.

I took a look at DDD this morning and it seems Tridef absolutely does not support SLI. So I guess it comes down to luck really and I didn't have any.

butmuncher · 22 Apr 2012 at 16:35

I think some games do have terrible slowdowns even with single cards, i think last game i played with tridef was maybe bf3 or Ac Revelations which worked ok with sli.
I know they do'nt support it but i find it works for me.

I do however use the 3dvision interlaced mod more than tridef so i 've only played a few games with tridef since going sli.

Martini1991 · 22 Apr 2012 at 23:44

For lol's I tried this on my Dell P2310H and it's "working"

My brothers Cinema glasses for whatever reason don't work, so I've ordered some "Passive 3D Glasses" hopefully they'll work.

If this works I'll be amazed.

Doesn't passive screens half your resolution?

So many theory's on this.
Something happens that's for sure but but it is'nt a killer by any means.
I love my passives, there so easy to use and 1080p 3d gaming looks good even though it's all half this or half that or alittle of this and so on.

There is a lot of difference between a 32",42" and 47" passive 3dtv, 32" looks lovely and crisp and 47" is more blurry but then this goes without saying as the pixel's get larger but it does make for a noticable increase in res the smaller the passive 3dtv is.
When i went from a 47" to a baddass 32" i felt like my gfx quality had increased, i'd never seen passive 3d gaming look so sharp with great detail.
Too small though so i'm back to a 47"

and i'm a happy camper

ALXAndy · 23 Apr 2012 at 12:32

Well I run my games at 1080p from the game's menu so I don't know. I heard it halves the height but graphically it looks as good as ever.

butmuncher · 24 Apr 2012 at 13:45

Just thought i'd include a pic of sli working with dirt3 using tridef

andybird123 · 24 Apr 2012 at 14:26

I don't really understand why you'd want to monkey around with .inf files from a zalman... I have an LG passive TV and it works with the standard Nvidia drivers...
