Motion blur photography of Samsung C24FG70 and C27FG70

A german site, Lim’s Cave has begun using the Blur Busters’ invented pursuit camera technique (peer-reviewed!) to capture some very good display motion blur photography of a Samsung C24FG70 / Samsung C27FG70 monitor.

The Samsung monitors use a motion blur-reduction strobe backlight during “Response Time” setting of “Faster” and “Fastest”.

New Motion Blur Reduction FAQ

There are now many dozen gaming monitors with Blur Reduction features, including NVIDIA’s Ultra Low Motion Blur (ULMB), as well as BENQ’s Blur Reduction / Dynamic Acceleration (dyAC), in addition to older LightBoost.

See our new Display Motion Blur Reduction FAQ.

This new FAQ helps to explain the pros/cons of display Motion Blur Reduction (strobe backlights), what strobe crosstalk is, how to fix amplified microstutters, and help you decide on the best Blur Reduction to look for in a new monitor.

Combining strobing (ULMB/LightBoost) with variable refresh (GSYNC/FreeSync)

Combining strobing (ULMB/LightBoost) with variable refresh (GSYNC/FreeSync)

There is research by Mark Rejhon back in year 2013 about eliminating motion blur during variable refresh rates (aka LightBoost + GSYNC simultaneously).

NVIDIA has published a new patent on combining GSYNC and ULMB. An actual demo by NVIDIA occured at CES.

Also, the Dell S2716DG has a “bonus bug” that simultaneously enables ULMB and GSYNC. This unintended mode does flicker badly at low frame rates, but it reveals high-quality blur reduction during variable refresh rate operation, especially at higher frame rates.

Plus, Marc Repnow of Display Corner has made available a new strobing algorithm that could cheaply greatly reduce flicker at low frame rates.
