Make Your Passive 3D Monitor or 3D HDTV Work with 3D Vision

February 11th, 2012 · 172 Comments · GeForce 3D Vision

Not that long ago Nvidia has introduced their “Optimized for Geforce” program that allows some certified passive 3D monitors such as Acer HR274H and Acer GR235HA to work with the 3D Vision video drivers, allowing you to use the full 3D Vision functionality with a passive 3D display. Prior to that in the old stereoscopic 3D drivers Nvidia had support for passive 3D monitors from Zalman, and although the newer Zaman 3D monitors were bundled with the iZ3D driver and not anymore with 3D Vision, they actually do work with 3D Vision and get optimized for the Optimized for GeForce functionality. If you have a passive 3D LCD monitor or even a passive 3D HDTV that is not supported by 3D Vision (Optimized for GeForce) you can actually quite easily make it work by installing a monitor driver with EDID override that will tell Windows and the video drivers that you actually have a different compatible display.

Here is an example using LG’s D2343P passive 3D monitor with installed Zalman ZM-M240W 3D Monitor EDID Override and the LG gets recognized as a Zalman 3D monitor. You need to install the INF driver from the link over the monitor driver you currently have installed from the Windows Device Manager, using the Have Disk option and if when get a warning message just confirm that you want the driver installed anyway. After that you may have to restart Windows in order for things to start working and the Nvidia video drivers to be able to properly recognize and activate the 3D support.

Opening the Nvidia Control Panel and going to the Stereoscopic 3D settings page you should see the “Optimized for GeForce” logo if everything is working properly and clicking the Test Stereoscopic 3D button should bring the Nvidia 3D test on the screen that should be working just fine when you put on the passive 3D glasses that came with the monitor. After that you can the 3D Vision Photo and Video Player and even play games in stereo 3D mode just like you would with an active 3D display and with the 3D Vision glasses. Of course using passive 3D would mean that you would have some limitations like the half vertical resolution when in 3D mode, the lower vertical viewing angle etc., but still you will be able to use passive 3D displays with your Nvidia graphics card and with all the features that 3D Vision offers, an not only with the iZ3D or the DDD TriDef 3D drivers, so you will simply have one more alternative available. I’ve tested this method and it works just fine even with the latest 295.51 beta video drivers from Nvidia, so you should have no trouble making it work. If you try this on your passive 3D setup, feel free to share your feedback and how it works with your specific 3D hardware, thanks to Butmuncher for finding out about this method.

Update: Since the Zalman EDID override does not support audio for HDMI connection to the monitor, you should use this driver only for DVI connection to the passive 3D display. If you wan to use HDMI connection and have audio over the interface as well, then you should install the Acer EDID override driver. Both INF files are included in the archive below, and special thanks to Greg Gilbert for providing the dump from the Acer HR274H display.

Here you can download the EDID override INF files that you would need for this to work…

    I just came back to say THANK YOU!
    It worked as a charm!
    Hugs from a happy man!

    I have LG D2343p and i did everything, it just doesn’t work for me.
    I mean i changed the drivers and i was able to use nvidia’s 3D but the 3D actually didn’t worked at all.

  • 3 andre pinto // Jun 15, 2014 at 23:44

    I have LG2343P and it works perfectly after installing the EDID override. George, you will have to install also the NVIDIA 3D Play activator to make this work.
    Using the Acer driver, I had to swap eyes in this monitor. Regards and thanks for help us solve this terrible issue.

    Hi, I thing this most is dead, but I have to ask becouse I need help, Nvidea panel does allow me to enable 3D and yes I see Optimization Icon, but whenerver I run a game (obiusly in 3D) it just renders something weird and nope hell no this is not 3D I can put the glasses in al the ways but I just see a messy image.

    Any Help?


  • 5 Bloody // Sep 16, 2014 at 19:45

    What is the model of the monitor you are using and can you post a photo of what the screen looks like when it is in 3D mode?

  • 6 Marc // Sep 17, 2014 at 00:21

    I’ve found the errot but i didn’t figured out how to solve it.
    When ever I start the game its set at 1080P 3D, most of games ar playable (not demanding ones), but whenever I put ingame resolution to 1024X720 for better performance it all blows up, if i dissble any kind of scaling I can play it at that res, but in a little windows, the game runs tiny and there ar all black borders. If I try to scall it to full size of the screen… you better wach it:

    Glasses OFF:

    Glasses ON:

    I’ve tried all, I put deskop res at the same, I used all Nvidia Panel scaling, I disabled “over scan” on monitor but nothing at all…

    I’m using a D2343 LG cinema 3D.

    Marc, unfortunately scaling of images does not work with passive 3D as you need each line on the screen to be a line of the image. So you either have to play at the monitor’s native resolution or at lower resolution without the monitor scaling the image to the whole screen (with the black bars). The polarizing filters applied on the screen are designed in a way that they can no longer provide the 3D effect when you scale up the image from lower resolution.

    Oh! I see, how fool I’ve been, it’s logical…. Thank you a lot, always I can’t see thing like this, huge lol.
    I would love to find something that allows me to run te game at 1080p but been rendered at 720P. As a example I can use the new Metros redux, you can put antianalising on 0,5 witch makes the game to render at half 1080p, much better performance and you se the exact same thing, already tested. And yes 3D 1080 is so demanding, thats why I was worried about that scalling “issues” becouse I have a lot better performance on 720p 3D even on my brand new GTX 770.

    The Acer driver works great with with LG-D2743, although I generally prefer Tridef. 3D vision works with far less hassle with Dolphin, and it’s nice to having the option.

  • 10 carl // Dec 7, 2014 at 00:22

    I have just got an AOC monitor, passive, (to replace the Zalman that died), and the 3D works with the Tridef prog, but not with the Nvidia screen, will this over-ride work with the AOC, I couldn’t see how it would.

    Monitor model -phlips 278G4
    its a passive 3D monitor and i have a nvidia gtx 660 graphics card but its does not work with my monitor so what can i do pls help me

  • 12 Maker // Feb 23, 2015 at 21:18

    I have a Zalman MW 220W(D), but the 3D isnt working for me. The stereoscopic function tries to use the monitor as it active ( I can see on each polarization the image for the left and right eye. You have any clue what I can do?

  • 13 Oliver // Mar 18, 2015 at 16:17

    I received my Philips 278G4 today and I got 3D to work, but unfortunately left and right eyes are reversed. It only works well when using the glasses with “top-bottom reversed”. Is there a way to change the .inf file to tell the Nvidia driver which side to use for which eye?

  • 14 Oliver // Mar 18, 2015 at 17:33

    After reading the proposal from a previous page I applied the registry hack which solved the issue. No it works fine.

    Now I’m able to use the LG UC970 passive 3D with 60 Hz. And it doesn’t lag at all like 3D TV play with the Emitter connected in 24 Hz.
    Thank you so much!

  • 16 John Zigmont // Sep 30, 2015 at 22:18

    I using the Acer HR274H EDID override on my Samsung UN56HU9000 and works like a charm.

    Little OT: is it possible to get side by side 3d?

  • 18 Marcus // Jan 20, 2016 at 00:57

    Hi all,
    I a trying to get 3d playing on my LG W2363D and a Geforce GT 740 on Windows 10 but nothing works. Windows tell that there was problem when installing driver.
    Is ther a solution for me?

    “LG 47LB750T webOS 3D SmartTV”, Asus K53SV Laptop having 2GB Nvidia GT540M, is there any possibilities to play games in 3D mode?

  • 20 GesherX3 // Mar 24, 2016 at 11:43

    funciona perfecto 3D pasivo y audio por HDMI gracias ^^

  • 21 Jesse // Apr 17, 2016 at 10:41

    I’ve got a Sony xbr850b 4k 3D tv. It plays 3d movies but I can’t get it to play my 3d still photos via a card in the usb slot like LG 3d tvs do. I was hoping I could connect it to my computer (it has a gtx 750) via hdmi and display them that way.

    Currently I don’t have a 3D computer monitor so use blue red 3D glasses or no glasses viewing methods when working in 3D on my computer monitor – so I don’t think I’ve even bothered to turn on the more advanced 3d nvidia options, which look like they use different glasses than I use for the TV (passive).

    1. Is it even possible?
    2. Do I need to do anything other than just plug in the tv to the video out / hdmi on the video card?
    3. would I need to buy an Nvidia 3D product like the glasses and install it before I could do what I need? In which case that’s not possible as I’d have to buy a 3D monitor too.
