New nVidia Video Drivers 186.18 and 3D Vision 186.18 Too

June 19th, 2009 · No Comments · GeForce 3D Vision

You can say that nVidia has released a new version of the GeForce 3D Vision drivers (186.16) without saying too much about it and even without updating the download section of the 3D Vision drivers on their website. The only way you can get the 3D Vision driver version 186.18 is by downloading the appropriate new video driver for your card that is designed for Windows Vista or Windows 7. Then you’ll have the latest Video driver, a PhysX driver and a 3D Vision driver all in one package – just run the downloaded Exe file and you’ll find the other installers in the C:\NVIDIA folder where the driver package gets extracted by default. There isn’t much information what is new in this driver, but probably we get new profiles for games, support for ViewSonic’s recently announced PJD-6210-3D and PJD-6220-3D GeForce 3D Vision-compatible DLP projectors and it seems some new applications will support 3D with the new version (Cooliris for instance)…

Update: Just installed and played a bit with the 186.18 drivers. I’ve found out about a big fault in them, nVidia had forgotten to include the USB device driver for the IR transmitter so after you install the drivers you’ll get a not working 3D Vision system. The solution is just to install the USB driver from the old version of the drivers that do have the device driver in them… we’ll probably see a fix if somebody notices that.

Update 2: nVidia will release an updated separate driver for GeForce 3D Vision that will have the missing USB driver for the IR transmitter… probably they didn’t include it, because the video drivers bundle version is intended mainly for use with paper or plastic anaglyph glasses… ;)

Download the latest nVidia Video Drivers 186.18 for Vista or Windows 7 with the 3D Vision update…

Samsung 2233RZ Locks Brightness in 3D Stereo Mode

June 19th, 2009 · 4 Comments · GeForce 3D Vision

When you are using the Samsung 2233RZ monitor in normal mode (2D) you can change its parameters without any problems, but when you switch in 3D mode some of the settings are being locked. It doesn’t matter what refresh rate has been set for the display at the moment – 60 Hz or even 120 Hz, you retain full control over the settings in the OSD menu of the display. As you can see in the image above I’ve set the brightness to 99 and the contrast to 60, but when I got in to 3D mode the settings change automatically to a preset value…

When you start a game in 3D Stereo mode with the 3D Vision glasses on and try to change the brightness and contrast of the monitor you can see that this function has been disabled. The brightness is set to 100 (maximum) and the contrast is set to 75 and you are not allowed to change these values. When you are back into a normal 2D mode of the display your previous brightness and contrast settings are being restored.

The good thing is that Samsung 2233RZ performs very well at these settings and there are no problems with color reproduction, and the same thing probably applies to the ViewSonic VX2265wm FuHzion 3D monitor. Maybe someone who actually owns a ViewSonic monitor can verify that, but I’m pretty sure that the same limit in the brightness also applies when 3D Stereo mode is activated.

The 3D Vision IR Transmitter – Up Close and Personal

June 18th, 2009 · 3 Comments · GeForce 3D Vision

Here comes the black box a.k.a. the IR transmitter that is the other major part of GeForce 3D Vision. This small black box allows you to start and stop the 3D Stereo mode by just pressing the front button with nVidia’s logo on it. This device sends an infrared signal to the glasses that is being used to synchronize the image displayed on the screen and the shutters of the glasses so that each eye sees just half of the frames displayed on the monitor.

On the back side of the transmitter you’ll find a mini USB connector that is used to connect the device to the computer, along with the scroll wheel used to set the level of depth when you tun on a 3D stereo mode. The scroll wheel is very convenient, because you can change the depth in every 3D application when you turn the 3D Stereo mode in real time. The level of depth is also controllable from the Stereo Drivers, but you need to go to the control panel of the video drivers in order to be able to modify it (the default value is 15%).
The connector on the right you see is only needed for synchronization when using a compatible DLP TV set as a display in combination with GeForce 3D Vision.

And now for the fun part. The image above is shot in infrared mode and thus the camera actually sees below the normally visible as black external surface of the transmitter. This is possible, because the cover of the transmitter has been made from a special type of plastic that blocks only visible light (appearing black in color), but at the same time passes all infrared (IR) light. This is done, because the transmitter sends infrared signals to the glasses and this type of light rays needs to pass through the external walls of the device. And all the bright lights you see inside the transmitter are actually infrared LEDs that are used to send the synchronization signal to the glasses. As you can see they are placed all over the inside of the transmitter which is needed to provide the best “connection” between the glasses and the transmitter, because infrared light transmission requires direct line of sight. With this design you don’t need to place the transmitter in a special location to get the best results, you can simply place it somewhere around the monitor and everything should be fine. Just be wary of some other devices transmitting infrared signals that may be active around you and the computer, because that might bring some interferences and break the synchronization of the glasses and the transmitter.
