Dual Monitor Wallpaper Maker
Create seamless dual monitor wallpapers for any resolution. Add bezel compensation to avoid cut-off images — perfect for 21:9 and 16:9 dual setups.
Why bezel compensation matters: Physical monitors have bezels (frames) that hide a few millimeters of your wallpaper. Without compensation, characters or key elements get sliced in half at the seam. This tool adds a configurable gap so your image flows naturally across both screens.
Core features:
- Auto-calculate total resolution — Left + Right + Bezel gap = exact pixel dimensions.
- Bezel gap compensation — Preset widths (0–20 mm) or custom pixel input, with realistic bezel color simulation.
- Independent screen editing — Adjust brightness, contrast, saturation, blur, hue, sepia, and color temperature per monitor. Fix color mismatch between different monitor panels.
- Panorama alignment — Fine-tune horizontal/vertical offset and zoom when splitting one wide image.
- One-click split export — Download the full combined image, or separate left/right files for each monitor.
