A lot of people were eagerly expecting the new 3D Vision-ready projectors from Viewsonic to become available on the market and to buy them to get really big Stereo 3D displays to play with, including myself. And now that the ViewSonic PJD6211, PJD6221 and PJD6381 3D-ready DLP projectors are already available on the market it seems that you better wait a bit more, before going for them especially if you wish to use them with your 3D Vision glasses. It seems that these projectors do have some problems working with 3D Vision and some people are having problems making them to work, although some suggest that setting the projector as a CRT display helps. It seems ViewSonic needs to release a new firmware update (according to Nvidia, but Viewsonic claims they need new drivers from Nvidia) to make the things work as they should and avoid any problems and this should probably happen by the end of September. And in those few weeks we might also see an new version of the 3D Vision drivers with even more improvements, one of which will probably be the addition of support for the new MPO image format for Stereo 3D pictures and of course more gaming profiles. So I’m just going to wait a bit more to see how things develop, instead of getting one of these new “3D Vision-ready” (or not yet ready) projectors now and I suggest you do the same if you are interested in them… ;)

I’ve already written what are the official specifications of Samsung’s 2233RZ 120Hz display, but today I’ve decided to verify how good the display actually is when it is being used in 3D mode with GeForce 3D Vision. As I already showed you Samsung 2233RZ locks the brightness level at 100 and contrast at 75, so there are the settings I also used when testing the display.

The first big surprise came because of the very good coverage of the SRGB, something that you don’t normally expect to see from a TN monitor, so here Samsung 2233RZ performed great. The black point I measured at the above settings was also quite good, considering that the display is set at high level of brightness and the maximum brightness level of white was pretty close to the value Samsung rates their product. The black point was at 0,293 cd/m2 and the maximum measured brightness for white was 285 cd/m2 while Samsung it at 300 candles per square meter which is pretty close, especially having in mind that brightness is important for 3D Vision. The contrast ratio considering the above actual measured values was 973:1 which again is pretty close to the rating of 1000:1 provided by Samsung and in 3D mode we don’t care much about the dynamic contrast values…

Now, up until now the Samsung 2233RZ performs very well especially considering it is based on TN panel, but unfortunately when I tested it see how the display performs in terms of color reproduction I was a bit disappointed. Now, don’t get me wrong… the display is great and it performs very well, but it seems it needs a bit of color calibration to make it even better and after calibrating it, it actually does give even better results. Before doing a calibration the display has some problems sustaining constant gamma value over different brightness levels, the color temperature also cannot be sustained at a certain value and the blue color needs a some tweaking. After a good color calibration these can be fixed quite good and thus the image representation becomes better and maybe, just maybe this may reflect into better gaming experience when using the monitor with or without 3D Vision… ;)
