The ultrawide OLED to buy in 2026, with sharper text than earlier QD-OLEDs and a price that undercuts many rivals.

Our verdict
The AW3426DW is the third generation of Alienware's 34-inch QD-OLED ultrawide, replacing the AW3425DW with a brighter panel, a 280Hz refresh rate and an RGB-stripe subpixel layout. TFTCentral found that the new layout removes the text fringing that hurt earlier QD-OLEDs, and measured about 1300 nits in HDR. RTINGS and Tom's Hardware praise its motion, input lag and value for an OLED ultrawide. There is no USB-C video input or KVM, and blacks look gray in a well-lit room.

- Bright HDR for an OLED
- Two HDMI 2.1 ports for consoles
