Wallpapers for an ultrawide screen

The shape. 3440×1440 is about 2.39:1 — marketed as 21:9. A 16:9 wallpaper stretched to fit looks wrong; one cropped to this exact size looks native.

Source size matters. You need an image at least 3440 pixels wide to avoid softness. Panoramas and wide landscape shots work best; drag the preview up or down to choose the band.

Dual screens? Two 1720-wide halves of this image won't match a real dual-monitor setup — use each monitor's own resolution instead.

Format. High-quality JPG is fine for photos; PNG for digital art with flat colour and gradients.

Other screens: 2560×1440, 1920×1080. Same shape, any size: 21:9.
