The Gefen 4K Ultra HD HDBaseT 2.0 Extender uses the HDBaseT 2.0 technology to extend HDMI up to 330' at 4K, using one Cat5e cable. The 1080p Full HD and 1920 x 1200 (WUXGA) 8-bit video can be extended up to 495'. The HDBaseT 2.0 Colligo platform ensures an even more robust and resilient connection than the industry standard HDBaseT. Resolutions up to 4K DCI-Cinema (4096 x 2160 @ 30 Hz 4:4:4) and 4K Ultra HD (3840 x 2160 @ 60 Hz 4:2:0), along with 7.1 channels of LPCM and HBR (High Bit Rate) lossless digital audio, are supported including Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-HD Master Audio.
RS-232 and two-way IR are transferred between the Sender and the Receiver to control the A/V source and the display. POH (Power over HDBaseT) technology provides power from the Sender to the Receiver and vice versa, using the same Cat5 cable that extends the HDMI and control signals. Only the Sender needs an external power supply. The POH standard ensures compatibility with other POH class-compliant devices.
The Gefen Syner-G software, with its powerful EDID management capabilities, speeds up configuration, performs real-time performance audits via Link Monitoring, and simplifies in-field firmware updates. Low-profile, surface-mountable Sender and Receiver units accommodate Gefen locking HDMI cables for secure connections.
