Reduce Motion Blur in 120Hz 2D mode on Samsung 3D Monitors

February 10th, 2013 · 4 Comments · Other S3D Tech


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.

    The biggest problem I had with the the Samsung S23A950D is the HUGE limiting factor in that the only connectors on it are HDMI whereas the Asus VG278H or VG278HE have dual link DVI. This means you will be cutting your framerate in half if you want use 3D Vision so I had to resort to “Side By Side” splitting instead. They really need to simply add lightboost into regular 2D monitors rather than you having to re-purpose a feature meant for 3D.

    I had to eventually replace that monitor though with an Asus VG278HE since it was defective (blue stuck pixel in the center even despite it being very new and the warranty replacement I got had several blue and red vertical lines all over the place (so obviously a very defective LCD panel). There is obviously a really bad batch of these on the market that somehow got passed quality control.

    Are you sure it was S23A950D, this one should have DVI, the TA series come only with HDMI?

    The S27A950D have Dual-DVI, Displayport and HDMI… Both Displayport and Dual-DVI work in frame sequential mode.
    Thanx for the information BLoody, i’ll try this trick when i’ll be back home tonight.

    I found out later that I had mixed it up with the T27A950 which looks VERY similar to the S23A950D. Sorry about that. Nevertheless, 3D Vision through HDMI is absolutely miserable. Dual link DVI is the way to go.
