Thanks to quantum dots, the 34-inch AW3423DW is an enormously colourful, fast OLED monitor. It dynamically adjusts its refresh rate to the graphics card via VRR. The fans on the built-in G-Sync module produce a discreet noise. The arrangement of the 3440 × 1440 pixels creates a green colour fringe at the top and a purple colour fringe at the bottom of high-contrast bright edges.
