Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, Turbo240, ToastyX Strobelight, etc.

How does backlight strobing work?

Just a quick question. How does backlight strobing work?
I made this picture so I don't have to explain much what I mean.
Is black frame shown every other frame or is it a new one in between? A or B?

It's B. So at 240Hz strobing, you still get 240FPS, not 120FPS. In other words, the backlight is toggled 480 times per second (switched off 240 times and switched on 240 times.) This produces much more crosstalk of course, but in return the effective framerate is not halved.
