Wireless HDMI cable Marmitek Stream S1 Pro 4K 60Hz - wireless HDMI extender, up to 30 m range

The Marmitek Stream S1 Pro is a wireless HDMI cable alternative that transmits video from a laptop or PC to a display without a physical HDMI lead. Designed for conference rooms, classrooms and home AV setups, the device supports up to 1080p/60Hz video natively and can be used with laptops that only have USB‑C ports. No software, app or Wi‑Fi network is required — the transmitter is powered by HDMI and the receiver by USB for straightforward, plug‑and‑play operation.

Advantages

The Stream S1 Pro replaces a conventional HDMI cable in meeting and presentation environments, reducing cable clutter and simplifying connections. It offers low latency (<120 ms) suitable for slides and standard video playback, plug‑and‑play setup without additional drivers, and compatibility with USB‑C equipped laptops. The transmitter and receiver are powered respectively by the HDMI source and a USB port, which keeps installation simple.

Suitable for

• Conference room presentations
• Classroom teaching and lectures
• Home AV setups where short-range wireless video is needed
• Meeting rooms replacing fixed HDMI cabling

Recommendations

For best performance place transmitter and receiver within line of sight where possible, keep distance within the specified range (up to 30 m) and avoid heavy obstructions or dense metal structures between units to maintain low latency and stable video quality.
