Overview
- Industry reporting and vendor claims say current wireless systems can carry 4K video over distances exceeding 30 meters.
- Leading options cited include Wi‑Fi Direct for direct device connections, Google Chromecast for app‑based casting, and Miracast for full screen mirroring.
- Smart TVs increasingly ship with built‑in projection features, allowing quick casting from phones, tablets, and laptops without extra hardware.
- HDMI remains preferred for competitive gaming, desktop setups, home‑theater purists, and professional AV because it offers near‑zero latency and a stable physical link.
- Modern wireless links use direct device‑to‑display encoding to preserve fidelity, though they can encounter Wi‑Fi congestion, electromagnetic interference, and configuration or security risks.
