Be Aware That 3D Vision Does Not Work at 144Hz on 3D Monitors
 
http://3dvision-blog.com/wp-content/...de-690x413.jpg

With the release of the first LCD monitors capable of running at 144Hz refresh rate that are also 3D Vision-ready there has been some confusion going on around regarding the stereoscopic 3D support that these displays can provide. There are already a few models on the market using 144Hz-capable TN LCD panels and these are: ASUS VG278HE, ASUS VG248QE and BENQ XL2411T. All of these are apparently targeted at 2D gamers as they do not have a built-in IR emitter or bundled 3D Vision glasses, but they do support 3D Vision if you have a 3D Vision kit and plug in an IR emitter for the glasses in your PC. The catch here is that these monitors can only work in 144Hz refresh rate when used in 2D mode (or plain 3D mode), but not in stereo 3D mode. If you use 3D Vision you will be limited to 120Hz as apparently 3D Vision does not support higher refresh rates yet, though it is not sure if it is just a software limitation or a hardware one like the glasses not being able to work at he higher refresh rate. Another variant is that the 3D Lightboost technology cannot function at the higher refresh rate, though that probably isn't the case.

Nevertheless buying one of these tree models so far of 3D monitors supporting 144Hz you should be well aware of the fact that using them in stereo 3D mode will be forcing maximum refresh rate of 120Hz. Even if you are able to select 144Hz refresh and the game seems to be running at the higher refresh rate in stereo 3D, it will be forced back to 120Hz and you can easily check that from the monitor's OSD menu in the Information panel where you can see the current input resolution and refresh rate. Now, for non stereoscopic 3D gamers the fact that stereo 3D works on up to 120Hz also means that you will not be able to take advantage of the 3D Lightboost technology at 144Hz in order to reduce motion blur. Playing at 120Hz in 2D mode with the 3D Lightboost enabled can bring significant reduction of the motion blur, making the moving images on the screen much smoother and going for 144Hz without the 3D Lightboost technology available may not be able to bring comparable results. So if you already have a more recent 120Hz-capable 3D monitor with 3D Lightboost technology support and you are considering of replacing it with a more recent 144Hz-capable solution you might want to reconsider about that, regardless if you are using it for 2D or stereo 3D gaming.
