Frequently Asked Questions
What is the difference between GtG and MPRT?
GtG (Gray-to-Gray) measures how fast liquid crystal molecules physically transition from one shade of gray to another (e.g., 0.5ms on Fast IPS / OLED). MPRT (Motion Picture Response Time) measures perceived eye-tracking blur caused by sample-and-hold display persistence. Even with 0.03ms OLED GtG, a 60Hz screen still has 16.7ms of MPRT blur because the image remains stationary on your retinas between refreshes.
How does BenQ DyAc / ZOWIE DyAc 2 eliminate motion blur?
DyAc uses Backlight Strobing (BFI). Instead of leaving the backlight on continuously, the backlight turns completely off while pixels transition and flashes on only when the frame is fully settled (typically for ~0.5ms). This mimics a CRT display, dropping eye-tracking persistence blur to near zero during rapid CS2 recoil sprays and 180ยฐ sweeps.
Is a 540Hz monitor clearer than a 240Hz monitor with DyAc?
A 540Hz native panel has 1.85ms of persistence blur without strobing. A 240Hz panel with DyAc+ tuned to a 0.5ms pulse achieves sharper moving text and crosshair clarity than native 540Hz, but at the cost of lower screen brightness and potential strobe crosstalk.
