The SIIG CB‑H21711‑S1 is a compact, active adapter that converts HDMI 2.0a video signals into USB‑C (DisplayPort Alt‑Mode), enabling connectivity from HDMI sources like laptops, consoles, and media players to USB‑C enabled displays or AR glasses. It supports stunning 4K @ 60 Hz with full YUV 4:4:4 8‑bit HDR and high refresh rates at 1080p (up to 144 Hz), making it ideal for gaming, professional video editing, presentations, or immersive AR applications.
This adapter is engineered as a unidirectional HDMI-to-USB-C converter—not reversible—allowing HDMI sources (e.g., PS5, Switch, laptops) to be displayed on USB‑C devices like XREAL Air glasses or portable USB‑C monitors . Featuring an active chipset (LT6711A) and compliant with HDMI 2.0a and HDCP 2.2 standards, it reliably supports 2‑ch stereo audio and ensures high bandwidth of up to 18 Gbps over DisplayPort 1.2 ]. The adapter includes a Micro‑USB port for external power, preventing compatibility issues with devices that don’t supply sufficient USB‑C power
Measuring just 2.8″ × 1.2″ × 0.5″ (7.14 × 3.1 × 1.22 cm) and weighing only 32 g, it’s highly portable and built with durable ABS housing. It delivers plug-and-play simplicity with no driver installation required, offering consistent performance for content creators, educators, and gamers

The active conversion chipset ensures reliable signal conversion without flicker or latency, ideal for smooth gaming and crisp video playback. The Micro‑USB power ensures stable operation even when host devices lack sufficient power, enhancing compatibility. Certified to come with a 2‑year warranty, it aligns with corporate and environmental compliance (RoHS, FCC, CE). While it’s not bidirectional—and won’t support USB‑C to HDMI—it excels in its purpose, providing clear 4K video output with HDR fidelity to select USB‑C displays.
