True holographic displays demand control of light at both nanometre scales and microsecond speeds. This work introduces an optically addressed metasurface spatial light modulator with sub-micrometre pixels and record spatiotemporal density, enabling real-time complex holography, 3D focusing, and beam steering. The platform achieves refresh rates compatible with dynamic wavefront control. A key step toward dynamic AR, LiDAR, and computational photonics systems.
