More About the Samsung 2233RZ 120Hz Monitor

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… ;)

Samsung 2233RZ Locks Brightness in 3D Stereo Mode

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.
