The Fast IPS Full HD (1920x1080) panel guarantees vivid, faithful colors and exceptional color accuracy with 178° viewing angles. This technology combines the speed of TN panels with the visual quality of IPS, offering sharp and uniform images even with the fastest movements.
With a 240Hz refresh rate, the monitor ensures ultra-smooth gameplay, without stuttering or lag. Every frame is displayed with maximum clarity, allowing gamers to react faster and with greater precision.
The 0.4 millisecond MPRT (Moving Picture Response Time) minimizes ghosting and motion blur. The result is extremely sharp image rendering, even in the most dynamic or action-packed scenes.
NVIDIA G-SYNC compatibility perfectly synchronizes the monitor's refresh rate with the GPU, eliminating tearing and stuttering. The result is smooth, stable gameplay free of visual artifacts, ideal for competitive games and simulations.
