Here is the second video comparing the 120Hz Samsung 2233RZ LCD display with a 60Hz Benq G2220HD LCD display and in this video you can see bigger difference compared to the one comparing the LCD with CRT at 120 Hz. The freeze frames below are from the original video, before being compressed and uploaded to youtube, so that you can compare the detail level of frames displayed on both monitors. On the freeze frames you can clearly see the advantages of the 120Hz LCD panel – less ghosting on fast moving objects, less tearing of the image with vsync set to disabled and more fluid movement of the surrounding area when you are panning faster in the game.
Take a note of the lights in the back of the last freeze frame, they do seem tripled on the 120Hz Samsung and just doubled on the 60Hz Benq monitor. Now this is clearly visible only on stop frames, but when looking at the video it is more like an advantage than a disadvantage. The thing is that this “tripling” of the objects makes the movement more fluid and natural that the doubled version, where you are like skipping the central part and the image seems much more jumpy.
As you probably know the 22″ Samsung 2233RZ LCD display is one of the first two true 120Hz LCD monitors available to the general public with the other one being the ViewSonic VX2265wm FuHzion. These are the two displays that usually go with Nvidia’s GeForce 3D Vision shutter glasses, providing great Stereoscopic 3D experience, but these monitors are also quite good even when used by themselves in normal 2D mode for gaming of course. And in order to see how good these new displays are are I took and old CRT monitor and compared it to Samsung 2233RZ with both running at 120Hz in clone mode, showing the same image. I opted for Counter Strike Source although not a big fan of the CS games, because the original CS game ca run up to 100Hz maximum, and the Source version is capable of playing at 120 hertz or frames (fps) which is more appropriate to be used when talking about the LCDs. Of course the v-sync was enabled in order to prevent the tearing of images while playing the game, so this problem is gone, however you can still notice the bit higher input lag of the LCD compared to the CRT display. You can watch the HD video above to see what are the differences and they are not much, because the two displays are pretty close in terms of response times with the LCD being in advantage here, because of better brightness, contrast etc. Use the pause button to be able to easily compare stop frames on both screens to get better idea, but here are also some stop frames in Full HD resolution taken from the original video, before being edited and uploaded to youtube.
What you can clearly see from these stop frames is that both displays are pretty close in terms of results with most of the time getting absolutely the same result on screen or with the Samsung LCD providing a bit better one. Still there are a few times where the LCD is a bit behind and in some situations you can actually see a triple image on a stop frame while the CRT has only double objects (the last freeze frame). But this can as well be considered to be an advantage, because this happens in some times where you actually have very fast moving objects and the triple image you see on the freeze frame actually makes it seem more fluid. Also have in mind that the displays run at 120Hz (120 fps) and the video is being shot with a camera running at 25 frames per second, but I also did some interesting comparisons shooting fast moving objects with 240 fps video (double the frame rate you get displayed). I’m still working on these videos, but I’ll also publish them here along with some videos comparing the 120Hz LCD to a normal 60Hz LCD monitor, so stay tuned… ;)
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.
