# 4K Video Wallpapers on Mac

Run stunning 3840×2160 and 5K motion wallpapers on your Mac without stutter, thanks to MacWall's GPU decode pipeline built for Retina displays.

4K video wallpapers look incredible on 27-inch iMacs and MacBook Pro Retina panels. **MacWall** decodes 4K H.264 and HEVC streams on the GPU, the same pipeline used by QuickTime and Final Cut playback.

## When 4K makes sense

- Native 4K or 5K displays
- Cinematic nature and space loops
- Desk setups plugged into power

## When to use 1440p instead

MacBook Air 13-inch and older Intel Macs may run cooler with 2560×1440 sources. MacWall scales video to fit, pick the resolution that matches your display for best quality-to-performance ratio.
