The GEFFEN GF-TPHD141 HDMI Extender, relying on HDBaseT technology and multi-functional control capabilities, perfectly solves these problems and becomes a preferred device for long-distance audio-visual transmission scenarios.
As an HDMI extender designed specifically for commercial scenarios, the core advantages of the GF-TPHD141 lie in "lossless transmission + bidirectional control + multi-scenario adaptation". It can extend high-definition signals over long distances via a single Cat5e/Cat6 Ethernet cable, while supporting bidirectional infrared control, balancing signal stability and operational convenience. It is suitable for various needs from small and medium-sized enterprise meeting rooms to large command centers.
I. Core Technology: HDBaseT Support for Reliable Long-Distance Lossless Transmission

The core competitiveness of the GF-TPHD141 stems from its in-depth integration of HDBaseT technology. This technology is specifically designed for transmitting multimedia signals over Ethernet cables, enabling lossless conversion of HDMI signals into standard HDBaseT signals for long-distance transmission via a single Cat5e/Cat6 cable. It fundamentally replaces the high cost and instability of traditional long HDMI cables.
In terms of transmission performance, the device delivers solid results: it supports HDMI 2.0 standard and HDCP 2.2 protocol, with a bandwidth of up to 600MHz and a transmission rate of 18Gbps. It can stably transmit 4K@60Hz (YUV444 8Bit) signals up to 60 meters, and 4K@30Hz or 1080P@60Hz signals up to 100 meters, fully covering the 230ft (approximately 70m) transmission scenario required by users. Adopting digital uncompressed transmission technology, it ensures zero picture latency and no distortion, with a maximum color depth of 12Bit. Meanwhile, it is compatible with the pass-through of high-definition audio formats such as DTS and Dolby True HD, meeting the needs of professional audio-visual scenarios.
Compared with ordinary HDMI extenders, the GEFFEN GF-TPHD141 has superior anti-interference capability—its metal case design effectively shields against electromagnetic interference, ensuring stable signal transmission even in complex environments with dense electronic equipment, such as data centers and large conference halls. This robust hardware design further enhances the device's long-term operational reliability.
