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.
