LG Display said it has completed an experiment and published a paper showing that higher refresh rates on gaming monitors improve players' real-time performance in first-person shooter games. The paper, "A Study on the Impact of Refresh Rate on Real-Time FPS Gaming Performance," found that players using monitors with higher refresh rates were better able to identify moving targets, improving both reaction speed and accuracy, the company said. The blind test involved 31 adult gamers who played a first-person shooter at four refresh rates — 60Hz, 240Hz, 360Hz and 480Hz — presented in random order. Researchers measured quantitative metrics including hit score and event interval time, as well as qualitative ratings on screen smoothness, ease of target tracking and overall preference on a five-point scale. Hit scores, a measure of shooting accuracy, improved 38 percent at 480Hz compared with 60Hz. The gain from 240Hz to 480Hz alone accounted for a 10 percent improvement, which LG Display said shows performance continues to rise as refresh rates increase, even from an already high baselin
