Dell Alienware AW3425DW

Alienware's AW3425DW is a 34.2-inch curved 3440x1440 QD-OLED with a 240 Hz refresh rate, 0.03 ms rated response, 99.3% DCI-P3 and DisplayHDR True Black 400. Tom's Hardware praises its out-of-box color accuracy, gaming motion and value, making it a strong ultrawide choice for gamers and creators who work in sRGB or DCI-P3. The main caveats are a 21:9 aspect ratio that won't suit every game, no headphone jack and no speakers.

  Editor's Choice at 4.5 of 5: accurate color straight from the box, strong HDR and motion handling and good value, with no headphone jack or speakers as the only listed drawback.
