Live Wallpapers for 3440 × 1440 Ultrawide Monitor
A 3440 × 1440 ultrawide is 21:9 of desktop in one panel, and it is the resolution where most wallpaper sources simply run out of image: photographs and video loops are authored for 16:9, so stretched to ultrawide they either crop to a letterbox or blur across the extra width. A procedural shader has no native resolution — the field is computed at whatever viewport you give it, so a 21:9 panel gets a composition drawn for 21:9 rather than a 16:9 frame with its sides cut off. That distinction is visible on this class of display more than any other: the horizon in a fluid simulation runs edge to edge without a seam, the symmetry of a Voronoi field survives the stretch, and the curved panel's own distortion is compensated for because the renderer projects against the aspect ratio instead of a fixed bitmap. At ~109ppi a shader also resolves cleanly at native scale while leaving GPU headroom for high-refresh setups.

Calibration & performance on this panel
This is the one corridor where 21:9 is the calibration baseline rather than a scaled afterthought: pick the 21:9 edition of any theme and the framing you preview is exactly what fills the panel, with no crop. Because ultrawide monitors often run above 60Hz, uncapped rendering is reasonable here — the benchmark column shows measured frame time per theme, and everything listed holds 165Hz-class loads because the heavy work stays on the GPU. If your panel is 21:9 but your second monitor is 16:9, scope the wallpaper to the ultrawide alone; spanning it across both forces a compromise resolution and throws away the aspect-ratio advantage that made the panel worth buying.
