Combining strobing (ULMB/LightBoost) with variable refresh

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

NVIDIA has published a new patent on combining GSYNC and ULMB.

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.
