The folks over at Blur Busters have extensively documented research showing that refresh rates of 1,000 Hz (and up) can reduce human perception of motion blur and flickering. And while the site notes that you eventually hit “diminishing returns” from all those extra frames—especially on smaller screens—there’s some evidence that you’d need a 40,000 Hz monitor to totally eliminate perceived motion blur on a sufficiently large and high-resolution monitor.
Perception research aside, it’s unclear just how many gamers are really interested in spending extra money for a display that breaks the four-digit refresh rate barrier. While LG hasn’t announced pricing details for the UltraGear 25G590B yet, other 1,000 Hz monitors tend to run hundreds of dollars more than comparable models with lower (but still more than adequate) maximum refresh rates in the 240 to 360 Hz range. At the same time, monitors with Nvidia’s GSync Pulsar and similar technologies use “rolling scan” pulsing backlights to reduce apparent motion blur, even on “slower” 360 Hz monitors.
LG says the 25G590B is “engineered specifically for first-person shooters” and mentions an “esports-optimized design” in its marketing materials, suggesting the display is targeting the small subset of gamers who actually play twitch-based reflex games for a living. For everyone else, we’d recommend ignoring the “larger number is better” impulse and saving your hardware budget for those increasingly expensive sticks of RAM.
