⚠️ IMPORTANT – Read Before Buying This booster includes a USB‑C power cable. You must connect it to a 5V/1A USB power adapter (not included) or to a USB port on your TV/game console. Without external power, the booster WILL NOT work. Also, you MUST use certified Ultra High Speed HDMI 2.1 cables (48Gbps) on both ends. Standard HDMI cables will cause black screen or flickering. ✅ Compatibility check before purchase – see product images.

【Active Signal Regeneration vs. Passive Connection – Solve the Root Cause】 This is an Active HDMI 2.1 Signal Booster with a built‑in chip that actively receives, reshapes, and amplifies degraded signals – fundamentally different from passive couplers that merely join cables. Designed for long‑distance runs (35ft, 50ft, even 164ft), it eliminates flickering, black screens, and dropouts. Real user: “50ft HDMI cable wouldn’t work at all – after adding this booster, the picture was rock solid.”

【True 8K/4K High‑Refresh Performance – Real‑World Verified】 Supports lossless transmission of 8K@60Hz, 4K@120Hz/240Hz with full passthrough for HDR10+, Dolby Vision, VRR, ALLM, and HDCP 2.3. Users confirm: *“Xbox Series X to 4K/120Hz TV – smooth, no lag”*; “PS5 over 35ft to projector – perfect signal, no handshake issues.” Note: This booster regenerates signals – it does not “upscale” lower resolutions.

【Mandatory USB‑C Power – The Key to Stability】 To guarantee absolute stability for 8K/4K high‑refresh signals, connecting the included USB‑C power (5V/1A) is REQUIRED. Without external power, the chip cannot operate at full capacity – leading to flickering or black screens. With power, you get rock‑solid performance every time. (Any standard 5V/1A phone charger works.)

【Resolution‑Based Distance Limits – Honest & Practical】 We specify maximum individual cable length for INPUT and OUTPUT at each resolution: 8K@60Hz / 4K@240Hz: IN ≤ 10m (32.8ft), OUT ≤ 8m (26.2ft) → Total ≤ 18m (59ft) 4K@120Hz: IN ≤ 11m (36ft), OUT ≤ 9m (29.5ft) → Total ≤ 20m (65.5ft) 4K@60Hz: IN ≤ 15m (50ft), OUT ≤ 10m (30ft) → Total ≤ 25m (80ft) User confirmed: “25ft Blu‑ray connection – picture became sharper, better color.” Unibody aluminum housing for heat dissipation and durability.

【Professional Setup Guide – Get It Right First Time】 For best results: (1) MUST use certified Ultra High Speed HDMI 2.1 cables (48Gbps) on BOTH ends (2) Connect Source → INPUT, Display → OUTPUT (3) Always connect USB‑C power Users appreciate the clear, honest specs: “Followed the guide – worked perfectly the first time.”
