GTB-HD4K2K-148C-BLK
The Gefen GTB-HD4K2K-148C routes one Ultra HD source to eight 4K Ultra HD displays. This HDCP-
compliant product has been specifically designed to support 10 layers of splitting/cascading for
flawless performance in large video distribution and signage applications, supporting hundreds of
displays. Resolutions supported include 4K Ultra HD (3860 x 2160 at 60 Hz, 4:2:0 color space), 4K DCI
(4096 x 2160 at 24 and 30 Hz), 1080p Full HD, and 1920x1200 (WUXGA). Deep Color, 3D, and
multichannel digital audio including 7.1 channels of LPCM and HBR (High Bit Rate) lossless formats
are also passed through. This product features Fast Switching Technology (FST). FST is a Gefen
firmware implementation for HDMI products. It eliminates the lengthy HDMI authentication process,
and allows disconnecting, reconnecting, or powering down HDTV displays without any of these
activities causing picture loss in other displays within the same distribution system. The choice
between built-in and passed-through EDIDs, and the ability to configure the EDID for 2-channel or
multichannel operation help customize your AV system to meet its operational requirements.
The Gefen 1:8 Splitter is the perfect choice for any small or large 4K video distribution system.
How It Works
The Ultra HD 4K Splitter is connected between the Ultra Hi-Def source and eight Ultra HD displays.
One or all of its outputs can alternatively be connected to other Gefen splitters to create a
cascaded system that distributes HDMI to a larger number of displays. Each splitter should also be
connected to an AC outlet using the included power supply. Once the source and the displays are
turned on and power is applied to the splitter(s), the 4K picture will appear on all connected
screens without any further set-up.
