Advantages

The QD‑OLED panel combines a blue self‑emitting layer with a Quantum Dot conversion layer to produce deeper blacks and improved color accuracy. With a 240Hz refresh rate and 0.03 ms GtG response time, the monitor reduces motion blur and ghosting for fast‑paced games. VESA certifications ensure high dynamic range and clear motion reproduction. OLED Care 2.0 includes pixel shift, panel protect and static screen detection mechanisms to decrease the likelihood of OLED burn‑in. Ergonomic design improvements include a bottom‑center 5‑way joystick navigator for easier on‑screen menu control.
