The EXT-DVIKA-HBT2 uses Gefen's implementation of the HDBaseT 2.0 technology to extend DVI over a single CAT 5e cable. The HDBaseT 2.0 Colligo platform provides additional features, such as USB and 2-way audio extension, and ensures an even more robust and resilient connection. Resolutions up to 1080p and 1920 x 1200 (WUXGA) are supported. HDMI resolutions up to 4K DCI-Cinema(4096 x 2160) and 4K Ultra HD (3840 x 2160) along with 7.1 channels of LPCM and HBR (high bit rate) lossless digital audio are also supported, when using DVI to HDMI cables. Supported HBR formats combine Dolby Atmos, Dolby TrueHD, DTS: X, and DTS-HD Master Audio. USB, RS-232, and 2-way L/R analog audio can be extended between the sender and the receiver to accommodate a complete workstation, including keyboard, mouse, select USB peripherals, microphone, headphones, and powered speakers. POH (Power over HDBaseT) technology provides power from the receiver to the sender unit, using the same CAT 5 cable, that extends the DVI, audio, and control signals. Only the receiver unit needs an external power supply. The POH standard ensures compatibility with other POH class-compliant devices.
