The GefenToolBox 4x4 Matrix for HDMI 1.3
The GefenToolBox 4x4 Matrix for HDMI 1.3 routes HDMI at resolutions up to
1080p@60Hz and 1920x1200@60Hz supporting multichannel digital audio
from any four Hi-Def sources to any four HDTV displays. The GefenToolBox
4x4 Matrix eliminates the need to disconnect and reconnect HDMI sources. It
works with any HDMI source that needs to be connected to an HDTV display,
supporting digital audio formats such as Dolby TrueHD and DTS HD Master
Audio. Each source is accessible at all times from any display by selecting it with
the included IR remote, the RS-232 port, or using the front-panel push buttons.
How It Works
Connect your Hi-Def A/V sources to the GefenToolBox 4x4 Matrix’s inputs using
the supplied HDMI cable. Connect up to 4 HDTV displays to the Matrix’s four
HDMI outputs also using the provided HDMI cables. Apply power to sources and
to the displays. A/V Sources may now be routed to display devices by using the
front panel buttons or the included IR remote control.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE GEFENTOOLBOX 4X4 MATRIX FOR HDMI 1.3
• EDID contains the A/V capabilities of a display device in regards to video
resolutions and audio formats supported. This information is used by the
source device to determine the format of the A/V signal on the outputs.
The GefenToolBox 4x4 Matrix for HDMI 1.3 incorporates advanced EDID
management to ensure compatibility with all sources and display devices.
See pages 15 - 18 for more details.
• The GefenToolBox 4x4 Matrix for HDMI 1.3 can detect the presence of Deep
Color (12-bit signal) automatically and will disable Deep Color EDID features
across all other outputs if any connected device or display is not capable
of processing Deep Color. This automatic behavior ensures compatibility
among all output devices in a mixed-device environment. This feature cannot
be disabled.
• When powering the GefenToolBox 4x4 Matrix for HDMI 1.3 or if the EDID
Mode is changed (see pages 4 - 5), the Matrix will undergo a momentary
initialization sequence. This is normal operation and may take a few
seconds.

How to Operate the GefenToolBox 4x4 Matrix for HDMI 1.3
The top panel of the GefenToolBox 4x4 Matrix for HDMI 1.3 contains a set
of LED indicators, displaying which input (source) is routed to which output
(display). This allows for easy management and viewing of all input and output
routing states.
There are four (4) rows of LED indicators on the front panel. To the left of the
LED indicators are four push buttons: Out 1, Out 2, Out 3, and Out 4. The
numbers along the top of the LED matrix represent the currently selected Input
(source): 1, 2, 3, or 4.
Example 1: Routing Input (source) 2 to Ouput (display) 3
1. Ensure that an HDMI cable is connected from the source to HDMI In 2 and
an HDMI cable is connected from the display to HDMI Out 3 on the Matrix.
2. Press Out 3 Button on the row of black buttons running vertically until the
LED under Input 2 is bright blue. If the LED does not immediately appear
under Input 2, continue depressing the Out 3 button until the LED under
Input 2 turns bright blue (Fig 1.1).

3. Once the LED under Input 2 turns bright blue, a picture will be displayed on
the display connected to Out 3 on the Matrix.
Note that in Fig 1.1, Out 1, Out 2, and Out 4 have also been routed. In this
case, the displays connected to HDMI Out 1, HDMI Out 2, and HDMI Out 3 are
receiving video from the source connected to HDMI In 1.
Example 2: Routing Input (source) 3 to Output (display) 1
Using Fig 1.1 as a starting point, press the Out 1 button two (2) times. The LED
matrix should now appear as follows:
Fig 1.2
LED 3 turns bright blue on the row labeled Out 1, indicating that Output (display)
1 is connected to the source on HDMI In 3.
In Fig. 1.2, the current state of the matrix is: Display 1 is connected to HDMI
2, Display 2 is connected to Source 1, Display 2 is connected to Source 2, and
Display 4 is connected to Source 1. Note that both Display 2 and Display 4 are
connected to the same source.
