When 4K/60Hz ultra-high-definition video, data streams, and control commands need to flow seamlessly with zero latency, zero distortion, and zero stuttering within the "last mile" space of conference rooms, classrooms, exhibition halls, and even industrial control rooms, a revolutionary wireless connection solution has become a necessity. With its profound technical accumulation, Chengdu EBYTE Electronic Technology Co., Ltd. has meticulously crafted the EWD612 series high-performance wireless screen transmitters. This is not a single product, but a flagship matrix covering complete applications from 1P60 (1-channel 1080P@60Hz) to 4K30 (4-channel 1080P@30Hz), aiming to completely replace outdated HDMI cables and create a new era of "wireless as wired" for ultra-high-definition audio-visual and data interaction.

Overview of the EWD612 series Wireless Display Device

The EWD612 series has a clear naming convention, revealing its professional product matrix planning: EWD612-TX/RX-[Video Specification][H/Q][B/C]

  • TX/RX: Clear distinction between Transmitter (TX) and Receiver (RX) roles, with defined responsibilities.

  • [Video Specification]: Core parameter identifier that defines the product's core carrying capacity.

  • [H/Q]: H represents high-speed transmission, Q represents high-quality or specific enhanced version, reflecting the performance focus of different models.

  • [B/C]: Usually represents version iteration or function optimization level, with version C being the latest generation or enhanced function version.

Based on this, we have built a clear "capability-scenario" matrix:

Matrix Value: The EWD612 series allows users to break away from the extensive model of "one model for all scenarios" through clear performance grading. Whether pursuing extreme fluency for single-person presentations, building complex command systems supporting multi-signal concurrency, or meeting cost considerations for large-scale standard deployment, users can find the unique and optimal solution in this matrix.

Technical Core and Groundbreaking Experience

Backed by EBYTE's profound technical accumulation in wireless data transmission (such as the E610 series' continuous transmission capability of up to 16Mbps), the core advantages of the EWD612 series lie not only in parameters but also in the following groundbreaking experiences:

Cinema-Grade Ultra-Low Latency and Zero-Compression Image Quality

  • Adopting a proprietary high-speed wireless protocol and advanced video codec technology to achieve end-to-end <50ms ultra-low latency. Whether flipping through PPT pages, moving the mouse, or playing videos, it achieves a "point-and-shoot" synchronization effect comparable to wired connections.

  • Supports H.264/H.265 efficient coding, optimizing bandwidth usage while ensuring image quality, ensuring clear 1080P@60Hz images with accurate colors, no motion blur, and no mosaic.

One-Touch Projection, Minimalist Interaction

  • Designed with a dedicated physical pairing button to achieve "one-click pairing, one-click projection". No complex network configuration or APP installation is required, allowing users to quickly establish a stable connection during first use, greatly reducing learning costs and usage barriers.

  • The receiver typically provides an HDMI output interface, and the transmitter is compatible with HDMI input, enabling plug-and-play functionality.

Industrial-Grade Stability and Anti-Interference Capability

  • Built with a powerful adaptive frequency hopping algorithm that can automatically avoid interference channels in complex 2.4GHz/5.8GHz coexistence environments (such as conference rooms with multiple Wi-Fi and Bluetooth devices), ensuring stable screen projection without flickering or disconnection.

  • Uses high-quality RF front-ends and optimized antenna design to ensure excellent transmission distance and wall-penetrating capability in open spaces.

Multi-Function Integration (Features of Some High-End Models)

  • In addition to high-definition video streams, some high-end models such as HQC can simultaneously transmit USB keyboard/mouse/touch signals and audio streams through a proprietary channel, achieving a complete solution of "one set of wireless screen transmitters for full wireless audio, video, and control".

  • Supports reverse control, allowing users to remotely operate the transmitter's computer device via the mouse on the large screen, enhancing interactivity.

Security and Expansion

  • Supports connection encryption to prevent unauthorized device access and screen peeking, ensuring the security of business meetings and demonstration content.

  • Some models may support cascade expansion to meet the needs of extra-large screens or multi-screen stitching scenarios.

Application Scenarios: Liberating Every Cable

  • Modern Smart Conference Rooms: Replace all HDMI cables between podiums and projectors/large screens to enable ad-hoc wireless projection from laptops and tablets, supporting quick turn-taking demonstrations by multiple users, creating a clean, efficient, and professional conference environment.

  • Digital Smart Classrooms: Teachers can hold tablets and move freely in the classroom for teaching, wirelessly projecting courseware and annotation content to the teaching large screen in real-time, enhancing interaction and improving teaching efficiency.

  • Corporate Exhibition Halls and Digital Signage: Flexibly arrange display terminals, with fully wireless content updates and screen control, easily achieving multi-screen linkage and content distribution.

  • Professional Audio-Visual and Broadcasting: As an emergency backup link or auxiliary signal source, providing a stable, high-quality wireless video transmission channel in studios and OB vans.

  • Medical Teaching and Surgical Live Streaming: In sterile or space-constrained operating rooms, wirelessly transmit signals from medical imaging devices such as endoscopes to external observation rooms, enabling interference-free remote teaching and consultation.

The launch of EBYTE's EWD612 series wireless screen transmitters marks a new stage where wireless screen projection technology has evolved from "usable" to "professional and easy to use". Through precise matrix-based product layout, it perfectly combines the segmented needs of different users with underlying powerful wireless transmission technology.

For users pursuing extreme fluency, the TX/RX1P60HQC series is the unrivaled flagship choice; for professional users needing to build multi-screen, multi-task collaboration systems, the TX/RX4K30HQC series provides unprecedented wireless carrying capacity. In summary, choosing the EWD612 series means saying goodbye to cable constraints and choosing a stable, efficient, professional, and future-oriented wireless audio-visual connection method. It is another milestone for EBYTE's leap from "wireless communication module expert" to "end-to-end, scenario-based wireless solution provider".
