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

February 11th, 2012 · 173 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…

Get The 2D Glasses If You Have Trouble With 3D Movies at Cinema

April 22nd, 2011 · 5 Comments · General 3D News


Do you remember the De-3D Cinema Glasses prank that ThinkGeek has pulled for April 1st this year, well the movie theater glasses that will turn a 3D movie into a 2D one are now real and you can buy them for $7.99 USD a pair. But why would you need glasses that make a 3D movie into a 2D one, when you can just go to a projection of that movie in 2D and not pay for a more expensive ticket for 3D projection? The answer is pretty simple, if you are not going alone to the cinema and only you have trouble when watching 3D and your friends still want to watch the movie in 3D, you can be with them and still watch in 2D with the special pair of glasses. The 2D Glasses are intended to be used in movie theaters using RealD projection technology and should be also compatible with most passive 3D television sets. They are not compatible with IMAX 3D movie theaters or ones using Dolby Digital 3D technology as these use different type of glasses, and of course they are not compatible with active shutter glasses solutions. Active shutter glasses such as Nvidia’s 3D Vision can also be modified to show 2D image from a screen displaying a 3D one, I’ve made a guide on how to do that.

Here is the real story behind the 2D Glasses from Hank Green:

In late 2010 I wanted to go see Tron Legacy. My wife was happy to come with me… as long as we went to the cheap theater where it was playing in 2D.

Really? Tron in 2D? What’s the point right? And then my wife told me something I never knew, she gets bad headaches when watching 3D movies.

She never complained about it, but there it was. I didn’t want my wife to be in pain, but I also didn’t want to go see Tron by myself. So instead of complaining (okay, in ADDITION to complaining), I got out my tools.

Instead of “recycling” the 3D glasses that my wife and I used during the movie, I took them home. After a lot of poking and twisting and gluing and cutting and cursing and sawing, I had created my first pair of 2D Glasses.

They’re not pretty, but I took them to see Voyage of the Dawn Treader in 3D and they worked! Katherine could watch the movie in 2D, and even switch to 3D for the action scenes!

She told some friends and by the next week, I had around 10 “orders” for these ugly 2D glasses. Stealing my raw materials from the theater became impractical, so I decided to get some nice ones made and make them available to the world.

What these 2D glasses actually do is to use two lenses with the same light polarization, instead of lenses with different polarization for the left and right eye as the typical passive polarized 3D glasses do. So basically in order to make a pair of 3D glasses into a one showing you 2D image from a 3D projection you just need to replace the right lens on the glasses with another left one. So instead of getting two slightly different images through each of your eyes and the brain fusing them into a 3D image with these glasses both your eyes will see only the left projected frame and it will still feel as a 2D image. And there goes the trouble and problem you may be experiencing watching 3D content, even though the projection would still be in 3D, you will be seeing a 2D movie with these modified glasses.

You can also order the 2D Glasses from Amazon, they are being shipped worldwide…
