Optoma WHD221 Wireless Transmitter and Receiver Professional Wireless Collaboration Solution The Optoma WHD221 is a professional-grade wireless presentation system designed for instant collaboration in corporate, education, and enterprise environments. By utilizing a standalone hardware-based architecture, it enables users to share Full HD 1080p content from laptops, tablets, or phones without installing software or connecting to enterprise Wi-Fi. With an ultra-low latency of 50–60ms and a robust 20-meter range, the WHD221 ensures stable, real-time performance for high-stakes meetings and interactive learning. What is the Optoma WHD221? The Optoma WHD221 is a dedicated wireless HDMI extender kit that replaces traditional cabling with a high-performance point-to-point link. The system consists of a compact USB-C Transmitter (TX) and an HDMI Receiver (RX). It is engineered for a “plug-and-present” workflow, where the transmitter draws power and data directly from the source’s USB-C port. Because it requires no applications or driver downloads, it is the ideal choice for secure environments and guest-heavy BYOD (Bring Your Own Device) workspaces. Key Features & Technology USB-C Wireless Casting Streamlines connectivity by using a single USB-C port for video output and power, eliminating the need for external power adapters for the presenter. Low Latency (50–60ms) Ensures a near-instant response time between the device and display, critical for smooth cursor tracking and high-definition video playback. 20m Transmission Range Provides dependable signal coverage for medium-sized meeting rooms and classrooms, allowing presenters to move freely without signal drops. Cross-Platform Support Compatible with any platform supporting DisplayPort Alt Mode over USB-C, including Windows, macOS, and mobile devices. Technical Specifications Parameter Official Specification Wireless Range 20m Wireless Frequency 5GHz Wireless Technology IEEE 802.11n System Latency 50ms ~ 60ms Resolution Support Up to 1080p Transmitter Inputs 1 x USB-C Receiver Outputs 1 x HDMI In-box Components USB-C TX, USB power cable, HDMI RX Net Weight 0.06 kg Applications & Use Cases Corporate Meeting Rooms: Enables fast switching between presenters without cable clutter. Higher Education: Allows educators to cast from mobile tablets while moving through the classroom. Huddle Spaces: Instant collaboration for small teams using BYOD devices. Temporary Setups: Perfect for trade shows and pop-up events where wired infrastructure is impossible. How the System Works The Optoma WHD221 operates as a hardware-only transmission system. The HDMI Receiver connects to the display (Projector or Flat Panel) and is powered via USB. The USB-C Transmitter is plugged into the source device. Once the button is clicked, the system establishes a secure 5GHz wireless link directly between the units. This point-to-point connection ensures that high-bandwidth video does not saturate the local office network or require IT configuration. Installation & Best Practices Line-of-Sight: For the most stable 50–60ms latency performance, maintain a clear line-of-sight between the TX and RX units. Power Management: Ensure the Receiver is connected to a stable 5V USB power source from the display or an external adapter. Distance Management: While the system supports up to 20m, optimal signal integrity in high-interference environments is best achieved within 15 meters. Why Choose Optoma WHD221?
