Best Overall
Alienware AW3425DW QD-OLED
Our verdict: A 34 inch QD-OLED with a 240Hz refresh and the best contrast of any curved ultrawide here.
The AW3425DW is a 34 inch QD-OLED curved at 1800R, with 3440 by 1440 resolution, 240Hz and a listed 0.03ms response time. It claims 99.3% DCI-P3 coverage, a 1,500,000:1 contrast ratio and HDR TrueBlack 400, plus G-Sync and FreeSync Premium Pro and a 3-year warranty. It sits in the $500 and up bracket.
It wins because QD-OLED switches each pixel off for true black, so a dark scene in a game or a film keeps its depth in a way no backlit panel can. The 1800R curve is gentler than the 1500R VA models, which suits people who dislike a tight bend. Against the Samsung Odyssey, you get a more manageable 34 inch width and a similar 240Hz refresh for much less desk space. The caveats are OLED traits: a text-heavy desktop shows slight fringing on some subpixel layouts, and static elements call for care over years of use.
Buy it if gaming, film and creative work share one screen, and your budget allows.
