The AW3426DW is a 34-inch ultrawide with a 3440 x 1440 panel that reaches 280 Hz, and it is brighter than its predecessor thanks to five-layer tandem technology. The AW2725DF, a 26.7-inch model, offers a 2560 x 1440 resolution, a 360 Hz refresh rate and a 0.03 ms response time. Both use Samsung-made QD-OLED panels, a display type that pairs OLED's deep blacks with a quantum-dot layer for vivid colour.

The two monitors are not direct rivals. The AW2725DF is the older model, dating from 2024, while the AW3426DW launched mid-year with a newer panel. Tom's Hardware's testing found colours accurate out of the box on both, with minor adjustments lifting the larger screen to 105% coverage of the DCI-P3 space. The reviewer also praised the ultrawide's low input lag and "perfect motion resolution", and called the smaller model "a near-perfect display for gaming or productivity when space is limited".
