CR4 Wireless HDMI Transmitter & Receiver 4K→1080p

CR4 Wireless HDMI Transmitter and Receiver kit wirelessly sends video and audio from USB-C phones, laptops, and PCs to an HDMI display with near-real-time, plug-and-play performance.

Skip cables and network setup: this compact CR4 kit establishes a direct peer-to-peer connection between a source device and a TV, monitor, or projector without Wi‑Fi, apps, or a router. It accepts 4K input while delivering smooth Full HD 1080p60 output with ultra-low latency, uses intelligent 5 GHz/2.4 GHz band selection for stable links, and includes multiple adapters for broad USB-C and HDMI device compatibility.

How simple is the CR4 setup for meetings or home theater?

Setup is designed to be quick and tool-free: plug the transmitter into your source, power both units, and attach the receiver to the display’s HDMI input. No pairing through an app or network credentials are required, so you’ll be ready to present in seconds.

• Plug-and-play transmitter and receiver — no router or Bluetooth needed
• Includes USB-C, Mini HDMI, Micro HDMI and USB adapters for sources
• Two USB-A power cables provided for immediate power
• Receiver connects to any HDMI-equipped TV or projector

Will the CR4 keep audio and video synchronized for calls and videos?

Yes — the CR4 prioritizes minimal delay, delivering 1080p at 60 Hz output while decoding 4K input to maintain tight audio/video alignment for presentations, video calls, and streaming. It’s tailored for use cases where visible lag would be distracting.

• Ultra-low latency design for near real-time transmission
• Supports Full HD 1080p60 output for smooth motion
• Audio/video synchronization optimized for conferencing and media
• Not intended as a zero-latency competitive gaming adapter

How far can I place the transmitter from the receiver and how stable is the signal?

The CR4 can reach up to 328 ft (100 m) in open line-of-sight environments, giving flexibility for large rooms, auditoriums, or home theater layouts. Real-world range will vary with walls, interference, and obstructions, but the device uses auto-switching between 5 GHz and 2.4 GHz bands to sustain the most stable connection possible.

• Maximum theoretical range: 328 ft (100 m) in open spaces
• Dual-band 5 GHz/2.4 GHz auto-selection reduces interference
• Works reliably in office and classroom RF environments
• Performance affected by building materials and competing networks

Which devices and displays are compatible with the CR4 kit?

The transmitter supports modern USB-C devices with DisplayPort Alt Mode (including iPhone 15 and newer via native USB-C), laptops with Thunderbolt/DisplayPort Alt Mode, cameras, and HDMI-enabled sources via included adapters. The receiver outputs HDMI only, so it requires a TV, monitor, or projector with a standard HDMI input.

• Native USB-C support for phones and laptops that output video (e.g., iPhone 15+)
• Adapters included: USB-C to HDMI (20 cm), Mini HDMI, Micro HDMI
• Receiver compatible with any HDMI-equipped display; no VGA/DP-only displays
• Energy-efficient operation under 2 W; standard 5 V / 1 A power supply

Who is this for? The CR4 Wireless HDMI Transmitter and Receiver kit suits professionals and home users who want a fast, reliable wireless display link without network configuration. It’s ideal for presenters, teachers, trainers, hybrid meeting rooms, and families setting up a clutter-free media area. Choose this kit when you need broad device support (USB-C phones and modern laptops), straightforward plug-and-play use, and extended wireless range for larger spaces. Note: ensure your source device supports video over USB-C before purchase.
