Look for a gaming monitor with a backlight strobing technology, which is usually called something along the lines of 1ms Motion Blur Reduction (MBR), NVIDIA Ultra Low Motion Blur (ULMB), Extreme Low Motion Blur, 1ms MPRT (Moving Picture Response Time), etc.

When enabled, backlight strobing further decreases motion blur in fast-paced games.

Note that when this technology is enabled, the screen’s maximum brightness is decreased, so use it only when gaming.

Furthermore, you can’t simultaneously enable FreeSync/G-SYNC and a blur reduction technology unless the monitor has a special feature for that.
