Some more good news for gamers interested in using 120Hz 3D capable monitors for gaming in 2D mode and not in stereo 3D, aside from the Nvidia 3D Vision-ready 3D Lightboost-capable 3D monitors it turns out that Samsung’s more recent 3D displays also use a similar strobe backlight mode that apparently also eliminate motion blur when activated even in 2D mode. Mark Rejhon reports on his blog that the Samsung S23A700D, S23A950D and S27A950D 3D monitors use a strobe backlight mode similar to 3D Lightboost that can be used on both AMD Radeon and Nvidia GeForce graphics in 2D mode and when activated you can get a significant reduction in motion blur compared to when using one of these Samsung monitors in 120Hz refresh in 2D mode. Just like the case with 3D Lightboost here the strobe backlight feature was probably originally designed to improve the stereoscopic 3D performance of these monitors, but later on users find that it can also benefit 2D gamers as well finally bringing a good alternative to CRT displays for high refresh rate gaming in 2D mode. On Samsung’s 3D monitors however the input lag seems to be more than on a 3D Lightboost monitor, still if you already have one of the compatible Samsung 3D-capable displays why not take advantage of the strobe backlight in 2D mode as well.
Instructions for Samsung 3D monitors:
– Set the refresh rate of the dislay to 120 Hz mode.
– Change “Response Time” to “Normal” from the monitor’s OSD menu.
– Turn on “3D” via the monitor’s OSD menu and select, frame-sequential mode.
– Keep using the monitor even for 2D gaming.
Note: On some computer configurations, your monitor might turn off when entering and exiting video games. If this happens, simply turn on your monitor again.
By now all of you should be aware of the fact that the newer 3D Vision ready monitors (including 3D displays in gaming laptops) supporting the Lightboost technology are a much better choice for stereoscopic 3D gaming than the older models, but it turns out that going for a Lightboost-enabled 3D monitor can benefit 2D gamers that want to take advantage of the supported 120Hz refresh rate. What the Lightboost technology does is to strobe the backlight instead of having it always on like on traditional monitors, and while this leads a lower overall brightness in 2D mode (actually making it look brighter in stereo 3D mode and with less crosstalk). The strobing of the backlight with Lightboost enabled makes the backlight turn on only when the pixels have reached their final stage in building the new image and the backlight stays off while the pixels transition from one stage to another. As a result all motion blur is being eliminated, making fast movements appear much smoother now. You can see how the image is being shown on the display without Lightboost enabled and with Lightboost on on the slow-motion video above made by Mark Rejhon who has experimented a bit with Lightboost and shared his interesting findings in our forum.
If you already have a 3D Vision ready setup and are using Acer HN274H B, ASUS VG728H or BENQ XL2420TX Lightboost-enabled 3D Vision ready monitor with integrated IR emitter, or have ASUS VG248QE, ASUS VG278HE, BENQ XL2420T or BENQ XL2411T along with an external 3D Vision IR emitter you can easily enable Lightboost in 2D mode as well. In fact some of you may have unintentionally seen this happen after exiting a game played in stereo 3D mode with the monitor remaining in 3D mode when back in the desktop (it seems darker than normal). All you have to do is set the Nvidia driver to always have the 3D monitor set in 3D mode from the Stereoscopic 3D panel int he Nvidia Control Center. The only disadvantage of having Lightboost enabled in 2D mode (have the monitor always run in stereo 3D mode) is that the brightness is lower than it is with Lightboost not being enabled, so you may need to increase the contrast more than you need it in stereo 3D mode. And while the lower brightness caused by the backlight not being constantly on due to the Lightboost being active can be considered as a disadvantage, these 3D monitors have way too high brightness in 2D mode anyway, so the reduction isn’t that bad, it actually brings the level of brightness closer to the level that won’t tire your eyes that much over a long periods of use… and you have no motion blur anymore.
And if you are not using 3D Vision and only have a 3D Vision-capable display, but no integrated IR emitter or an external one you would have to resort to using and EDID INF override driver to make the Nvidia drivers think that you actually have a compatible 3D monitor with full support for 3D Vision. This actually makes the ASUS VG248QE, ASUS VG278HE, BENQ XL2420T or BENQ XL2411T 120Hz capable monitors a lot more interesting for people that are willing to be able to play games in 120Hz 2D mode and don’t care much about stereoscopic 3D gaming. The reason you need to trick the video drivers you have 3D Vision is that the Lightboost technology has been developed for use in stereoscopic 3D gaming, and though it can also benefit people playing in 2D, probably nobody though about that at the time is has been developed. So without the drivers thinking you have support for 3D Vision (even if you don’t actually have IR emitter) you can still enable Lightboost in 2D mode.
