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.

Samsung 2233RZ Monitor Specifications

June 16th, 2009 · No Comments · GeForce 3D Vision


Samsung 2233RZ is the 120 Hertz (120 fps) monitor that is being sold as a bundle with the GeForce 3D Vision glasses in the European market and as a standalone LCD display of course. Even if not using it in 3D stereo mode you can still set the monitor at 120 Hz refresh rate and have a better and more responsive LCD display than all other models currently available on the market (ViewSonic VX2265wm is the other similar product). But lets get to the technical specifications of the display in order to see what it actually offers in both 2D mode and in 3D when used in conjunction with 3D Vision glasses.

Samsung 2233RZ is a 22-inch monitor with widescreen aspect ratio of 16:10 (not the recently popular 16:9) and resolution of 1680×1050 (again not Full HD as the new 16:9 22″ displays already available). The display is using a TN panel with maximum brightness level of 300 cd/m2 (the high brightness is very important when in 3D mode), contrast ratio of 1000:1 and 20000:1 dynamic (unusable in 3D mode) and response time of up to 3-5 milliseconds (3ms for gray-to-gray and 5ms for black-to-white transitions). The viewing angles are quite good at up to 170º horizontal and 150º vertical at contrast ratio of more than 10:1 which you’ll notice when you see the display, and I should note that there is no glossy and mirror-like filter in front of the display, but a matte one which is probably better when used with 3D Vision. The display has only Dual-link DVI-D display port for connection to a PC and you need Dual-link cable in order to provide 120 Hz refresh rate over the DVI interface at 1680×1050 resolution, otherwise you’ll be limited to 60 Hz over a single-link cable. The thing that differentiates Samsung 2233RZ and the monitor apart from their external design of course is the lack of integrated speakers here as opposed to ViewSonic’s solution. One other thing that I noted in the specifications is that the Samsung 2233RZ typically uses of up to 50W per hour as opposed to up to 45W in the case of ViewSonic VX2265wm FuHzion. Also it seems that the ability to use the additional dynamic contrast is only available on Samsung’s display, but you should note that it should not be used when playing in 3D mode with the shutter glasses. When you enable the 3D Stereo mode it seems that Nvidia’s stereo driver automatically sets the brightness to the maximum level and it disables the ability of the user to lower it through the menu of the monitor.

Nvidia GeForce 3D Vision Kit

June 16th, 2009 · No Comments · GeForce 3D Vision


Recently Nvidia is making quite a few new products that are not in their main focus and by that I mean the GPU business. Some of the new interesting products coming out from nVidia are for instance the ION platform or the Tegra, products based on which are just now slowly starting to come out in the market. Actually there is one more interesting solution that was announced a few months back, but just recently became available in Europe – GeForce 3D Vision. These are basically LC shutter glasses (often referred as LCD shutter glasses which is not entirely correct) that are designed to work with a suitable display that can provide at least 100 Hz or higher refresh rate. Now as normal LCD displays cannot provide such a high refresh rate or actually we better use the term frame rate here when talking about LCD displays we are going to need a new type of LCD displays. So Samsung and Viewsonic provided a solution in the form of 22-inch LCD displays with 120Hz refresh rate so that they can be bundled with the 3D Vision glasses to provide the best experience. So far ViewSonic VX2265wm is only available on the American market and the Samsung 2233RZ is available in Europe both bundled with nVidia’s 3D glasses or as a standalone monitors. Apart from these two monitors you can also use the GeForce 3D Vision glasses with a normal CRT display (that can provide high enough refresh rate) if you still have one of these lying around. There is also support for some DLP TV sets and 3D projectors, but these are still not very popular and widely available so the best way is just to get the 22-inch Samsung or Viewsonic LCD display available where you live. By the end of this year other LCD display manufacturers should also start to provide suitable models with high refresh rate, bigger resolution and size, but we will have to wait and see.

With the help of Nvidia GeForce 3D Vision you can start enjoying a way more impressive 3D gaming experience, watch suitable 3D movies and even look at digital photos in 3D. Of course the most interesting and impressive features is the use of the technology for gaming, making most of the new titles and a lot older games a lot more impressive. By utilizing the 3D Stereo shutter glasses you can experience all 3D games in a new way, even games that you can completely finished playing will seem different to you when you’ll be able to see the depth of the 3D world around you. Of course not all games work perfect out of the box, but most of them have built-in profiles and provide information and good enough result by default and then you can tweak them a bit to achieve better results based on your personal preferences. But even if a game doesn’t have a profile there is a high chance it will work fine with some minor tweaking or even without having to do anything special, you just have to try. And the list of games that have serious problems or are not working at all is very small indeed and there is a chance that they may become supported in later updates of the drivers. I’ll tell you some of the games that provide the best results combined with GeForce 3D Vision that you should definitely try if you have the chance to test this 3D Stereo product or even if you buy one yourself. Anyway there is way more to come about Nvidia GeForce 3D Vision and not only about it, so stay tuned for more information… ;)
