2026 Wireless HDMI Transmitter & Receiver Set – Supports 4K Decoding, 1080P OutputPlug-and-Play Portable 5G+2.4G Extender: Transmits Audio/Video from Laptops/Desktops/TV Boxes/Projectors to Displays

The NUTCITY CHD-21 is a plug-and-play wireless HDMI extender that cuts cable clutter between source and display in under 10 seconds — no apps, no Wi-Fi network, no pairing rituals. Dual-band 5G+2.4G signal delivers stable transmission up to 80 meters, covering conference rooms, classrooms, and living room setups without interference issues.

The system supports 4K source decoding with 1080P output, striking a practical balance between input quality and reliable wireless throughput. Ultra-low latency keeps audio and video in sync for presentations and streaming alike.

Output is capped at 1080P even with a 4K source — fine for most use cases but not ideal if you need pixel-perfect 4K at the display end. Best suited for office workers, teachers, and home theater setups that prioritize instant wireless convenience over maximum resolution.
