Features
• Simultaneously display a 4K Ultra HD source on up
to 2, 4 or 8 Ultra HD displays (depending on splitter
model)
• Specifically designed to support 10 layers of splitting/
cascading in large video distribution and signage
applications, supporting hundreds of displays
• Support resolutions up to 4K Cinema (4096 x 2160
@ 24 and 30 Hz), 4K Ultra (3860 x 2160 @ 60 Hz 4:2:0
color space), 1080p Full HD and 1920 x 1200 WUXGA
• 12-bit Deep Color at 1080p, 3DTV pass-through, Lip
Sync pass-through
• Fast Switching Technology (FST) speeds up HDCP
authentication
• EDID management and Audio Mode selectors for
rapid integration of source and displays
• Supports LPCM7.1, Dolby® TrueHD, Dolby Digital®
Plus and DTS-HD Master Audio™

Benefits
• Flat pack surface-mountable...splitters mount
almost anywhere
• FST eliminates the lengthy HDMI authentication
process
• FST allows disconnecting, reconnecting, or
powering down HDTV displays without causing
picture loss on other displays within the same
distribution system
• EDID management allows the choice between
built-in and passed-through EDIDs
• Daisy-chain/cascade capability allows connection
of up to hundreds of displays
• Incorporating splitters with extenders can create
simple to design and install video distribution
systems with remote display clusters with IR, RS-232
or IP control of remote displays or other devices
• Support the use of DVI sources and DVI displays with
HDMI-to-DVI adapters (not included)
Gefen GTB-HD4K2K-142/4/8C-BLK Splitters feature three settings that help improve
performance and stability in HDMI distribution systems.
FST - Fast Switching Technology (FST) Fast Mode improves performance when
connecting/disconnecting HD sources, and powering HD displays ON/OFF.
Slow Mode will follow the standard authentication process based upon the HDMI
and HDCP specifications. Slow Mode is recommended when the source does not
support multiple devices.
Audio- As part of EDID management, splitter audio output can be set to 2-channel or
multi-channel when EDID is set to Int (Internal). 2ch Mode is used when all displays
and/or sink devices support only 2-channel LPCM audio. Multi-ch Mode is used
when all displays and/or sink devices are capable of multichannel audio.
EDID- Extended Display Identification Data (EDID) contains the A/V capabilities of a display device in regard
to video resolutions and audio formats supported. This information is used by the source device to
determine the format of the A/V signals on the outputs. In Ext Mode (External) the splitter 'builds' an EDID
based upon the highest common video resolution and most superior audio format supported by all
displays. This EDID is then transmitted to the source device. In Int Mode (Internal) the built-in internal EDID
provides the source device with a 'generic' EDID that can be used by all displays.
