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…
