Wallpaper tips
🖥️
Common resolutions: 1920×1080 (Full HD), 2560×1440 (QHD), 3840×2160 (4K). Match your screen resolution exactly for the sharpest result.
📐
Using an image that's too small causes blurring. For 4K displays, start with the highest resolution image you have.
🎨
For dual-monitor setups, combine both widths (e.g. 3840×1080 for two 1920×1080 screens) into a single wide image.
💡
JPG at quality 95 produces excellent wallpapers at manageable file sizes. PNG is lossless but can be 5× larger for photos.
