The Tech-Protect UltraBoost is an Ultra High Speed ​​certified HDMI 2.1 cable designed to fully utilize the capabilities of modern audio and video equipment. It supports 8K resolution at 60Hz and 4K at 120Hz, as well as Dynamic HDR, VRR (Variable Refresh Rate), and Dolby Atmos. It is also fully backward compatible, making it suitable for older devices.

Inside, you'll find a 30 AWG pure copper conductor, ensuring stable and interference-free signal transmission even with high data rates. The outer shield is a braided black cotton braid combined with a durable PVC jacket, protecting the cable from abrasion and tangling. The robust connector housing, made of aluminum alloy, effectively dissipates heat and suppresses electromagnetic interference, while oxidation-resistant gold-plated contacts ensure a clean connection for years to come.

Dynamic HDR transmits HDR data frame-by-frame, adjusting the image's brightness, contrast, and color tones individually for each scene, creating a deeper, more natural image. The cable is officially certified for Ultra High Speed ​​HDMI 2.1, confirming that the product has been tested by an authorized testing center.

The cable works in all connection modes – Mirror Mode (duplicates the image on a second screen), Extended Mode (extends the desktop), and Game Mode (low latency with a high refresh rate). Standard HDMI Type-A (male-to-male) connectors ensure full compatibility with a wide range of devices – from consoles, TVs and projectors, to AV receivers and gaming monitors.
