How to Use Any 3D DLP Projector Together with 3D Vision

December 24th, 2010 · 23 Comments · GeForce 3D Vision

I’m getting a lot of questions from people that bought a 3D DLP projector how to make it work with 3D Vision and when I see the device model I immediately notice that it is not in the list of 3D Vision-certified DLP projectors. This means that you will not be able to just connect the projector, install the drivers and everything to start working with 3D Vision, it normally means you cannot make things work, however you are not out of options. You can make a simple modification that will make things work somewhat, but there might also be some side effects, so you should be careful. Most of the 3D DLP projectors use the DSUB15 analog connector for connecting and transferring 3D data, however the more recent Nvidia-based video cards do come with digital DVI outputs only. So in order not to destroy the VGA cable, you will also need a simple VGA to DVI adapter like the one on the picture above (in this case a single link DVI-A) to make things work, but you can also use a single or dual link DVI-I (DVI-D will not work). Then you just have to break the two pins that are pointed out with red arrows on the picture and you are almost ready to go…

The two pins you are going to remove from the adapter are used for the Extended display identification data (EDID), a standard that is used to identify a monitor connected to a PC and what the display is capable of (resolutions and refresh rates). Without those two pins the computer will not be able to automatically recognize the projector you are connecting and it will be treated as a generic analogue display (CRT), because you are using the adapter connected to the projector through a VGA cable. And since the 3D Vision drivers actually do support all sorts of CRT displays if they can manage to provide you with at least 100Hz refresh rate, you can pass the 3D Vision Setup Wizard and have 3D Vision working. But before that you will need to load up some sort of a driver to let windows know what modes or refresh rates your “CRT display” actually supports. I prefer to use the Nvidia Control Panel and add a custom resolution at 120Hz refresh rate and work with that, instead of loading a driver for Acer H5360 for example for other 720p capable not officially supported 3D DLP Projector.

As I’ve mentioned already, this method works in order to allow you to enable the 3D Vision to work with pretty much any 3D DLP projector, treating the projector as a CRT display. The problem that you might get is related to the fact that you may get the left and right frames reversed and that can ruin the experience, unless you want to wear your glasses upside down. There are some measures to help you counter that issue, like reversion the left and right frames of a video from the software player you may be using or the photo viewer for 3D photos, some projectors also have a built in mode to reverse the left/right frames although that does not always work and so on.

List of 3D Vision-Ready DLP Projectors:

– Acer X1261-3D
– Acer X1130P
– Acer H5360
– Acer X1110
– BenQ MS612ST
– DepthQ HD 3D Projector by LightSpeed Design, Inc.
– DQ-3120 by LightSpeed Design, Inc.
– Optoma GT360
– Optoma GT720
– Optoma HD67
– Optoma HD66
– Optoma HW536
– Optoma IS500
– Optoma XE149
– NEC NP216
– Sanyo PDG-DWL2500
– ViewSonic PJD6531w
– ViewSonic PJD6220-3D
– ViewSonic PJD6210-3D
– ViewSonic PJD5351
– ViewSonic PJD5111
– ViewSonic PJD6381
– ViewSonic PJD6211
– ViewSonic PJD6221
– ViewSonic PJD6241
– ViewSonic PJD6251
– ViewSonic PJD5112

What I would recommend however is to save a lot of trouble and just go for a 3D Vision certified 3D projector if you are now going to buy one from the list above, especially when talking about gaming in stereo 3D mode. Obviously going for Acer, Optoma or Viewsonic should be the best choice as they already have a wide product line that supports 3D and you can choose the best model that fits your requirements better. But if you’ve already bought a 3D DLP projector that is not officially supported and you don’t want/have additional money to spend for a new one, then the above method might help you get things running…

Workaround Solution for Viewsonic PJD6531w Users with 3D Vision

June 20th, 2010 · No Comments · GeForce 3D Vision

Nvidia has provided a temporary solution for the owners of the Viewsonic PJD6531w 3D DLP projectors and 3D Vision running into problems when setting up 3D mode using the 3D Vision wizard.Have in ind that what they’ve published is just a temporary workaround until a fix is made available (probably with the release of the next driver update). The step by stem guide available as a knowledgebase article will give you directions for configuring the Viewsonic PJD6531w with the Nvidia 3D Vision glasses and it is available here: I am having trouble setting up the ViewSonic PJD 6531w using CD v1.29 (v257.21)?

The cause of the bug is that the software is choosing the optimal mode reported by the projector which in case of the Viewsonic PJD6531w is 1280×800. However, the projector needs to run at 1280×720 rezolution @ 120Hz and thus the wizard will report an error. Nvidia is hoping to have a fix for that issue ready by the next 3D Vision driver update and meanwhile if you already bought Viewsonic PJD6531w projector, then you can use the temporary workaround for the time being…

Workaround for 3D Vision Video Player Not Willing to Play a Video

May 29th, 2010 · 6 Comments · GeForce 3D Vision

By now you should be well aware that the 3D Vision Video Player and the Stereoscopic Player sometimes can behave a bit strange when you try to play some stereo 3D video files, even though you have the right codecs installed and setup in the player. This strange behavior can sometimes be annoying, especially after you mess with the codecs and the player settings in order to fix the issue, but nothing seems to help in resolving the problem. So instead of trying to recompress the video file to more “friendly” formats and thus having to wait more or loose some of the original quality you can try another alternative workaround that may help you play the 3D video…

I’m talking about the use of a simple AviSynth script to warp the video into an AVI compatible stream that should help you play the 3D video file in the 3D Vision Video Player or the Stereoscopic Player. You need to download and install the free AviSynth for this method to work. Then you need to create a text file (name it for example workaround.avs) and enter the following line in it:


You can either place the AVS file in the same directory as the video file and just change the name of the video, in this example sailboats-stereo-3d.m2t or to enter the full patch to the video file and have the AVS script anywhere you like. Then you just need to open the workaround.avs script in the 3D Vision Video Player or the Stereoscopic Player instead of directly the problematic video file, you need to choose the 3D format and then the video should start playing. Of course this workaround may as well sometimes behave weird and not work, but it doesn’t take time and it won’t hurt to try it out if you are getting trouble with some stereo 3D videos you want to watch.
