A single flat OLED panel, cut to 27 inches at 2560 × 1440. At 280 Hz with 0.03 ms response, motion stays sharp at any speed, and contrast is limited only by how dark your room is.

Our flagship. A 49-inch QD-OLED panel curved to 1800R, at 5120 × 1440 and 240 Hz. Every pixel makes its own light and switches fully off, so black on Nocturne is simply the absence of light.
