Description

StarTech HDMI21-CBL-SLIM-3F Ultra Slim HDMI 2.1 Cable

Overview

The StarTech HDMI21-CBL-SLIM-3F is a 3-foot, ultra-slim HDMI 2.1 cable designed for high-bandwidth video and audio transmission. Its flexible TPE jacket and thin 4.0mm OD make it ideal for installations where space is constrained, such as behind displays, in tight AV racks, or within conduit runs. This cable supports advanced video features like 8K60Hz and 4K120Hz resolutions, HDR10+, and a 48Gbps data transfer rate, ensuring uncompromised signal integrity for demanding applications like high-resolution surveillance monitoring or next-generation gaming setups.

Compatibility

This HDMI 2.1 cable is backward compatible with previous HDMI versions but is specifically engineered to leverage the full capabilities of HDMI 2.1 sources and displays. It supports uncompressed resolutions up to 8K30Hz and 4K144Hz, and with DSC 1.2a compression, it can handle up to 10K60Hz and 8K144Hz. It also supports 7.1 channel and 32 channel audio, making it suitable for advanced home theater and professional AV systems. For surveillance, it ensures you can connect high-resolution NVR outputs to 4K or 8K monitors without signal degradation.

Installation Notes

The cable jacket is constructed from TPE (Thermoplastic Elastomers), offering superior flexibility and durability compared to standard PVC. The aluminum-Mylar foil and braid shielding minimize electromagnetic interference, protecting signal integrity. The connector plating is gold, providing reliable connectivity. Operating temperature range is 0°C to 40°C (32°F to 104°F), and storage temperature is -20°C to 70°C (-4°F to 158°F). The wire gauge is 34 AWG, contributing to its slim profile.
