Dell Alienware AW3426DW Review: The New Ultrawide OLED to Beat

Dell’s new 34-inch Alienware AW3426DW adopts Samsung’s upgraded 2026 QD-OLED ultrawide panel with RGB-stripe subpixels for sharper text and better image clarity.

The monitor improves HDR performance with up to 1,300 nits peak brightness, better ambient-light handling, and Dolby Vision support.

It still targets gamers with a 280Hz refresh rate, though that is lower than some 360Hz rivals.

At $800, it brings the latest ultrawide QD-OLED upgrades to a more affordable price point than competing models.
