The IDK’s GF-100 is a portable digital video checker for HDMI/DVI devices, providing source/sink tests,
cable/transmission line tests, and monitoring DDC function between source and sink devices.
■Source test (P.19)
●Displays the following statuses on the LCD display or browser: resolution, frequency, presence or
absence of audio, status of DDC voltage, and the like.
●Outputs status changes to a browser or ICT/IP port “2200”.
●Has an EDID emulator (P.29).
GF-100 Source device
[Fig. 2.2] Source test
■Sink test (P.34)
●Displays the following items on the LCD display or browser: supported resolution, audio supported/not
supported, HDCP compliant/not compliant, EDID, and other information.
●Outputs test patterns (video)/test tone (audio). (P.40)
●Saves up to five EDIDs of the sink device in the GF-100.
●Downloads the saved EDIDs onto the PC via the browser; they can be read with analysis software.

■DDC monitor (P.47)
●Outputs the DDC communication data of the source and sink devices to browser or the TCP/IP port
“1100”.

■Cable/transmission path test (P.50)
●Outputs the test signals and measures the quality (bit color) of the cable/transmission path.
●The test signals consist of random data and data that is under tougher condition (the hardware of the
cable and its transmission).
●The resolution and color depth of the test signals can be selected.
●With two GF-100 devices, the transmission path test between two distant sites can be performed.

■Checking sink status (P.34)
Check if the GF-100 can detect the sink device correctly (P.35).
<If the GF-100 cannot detect the sink device>
The sink device or cable 1 has a problem. Check the power supply, connection and input
switching (if there are some) of the sink device.
Perform the cable test (P.50) for cable 1 if necessary.
<If the GF-100 can detect the sink device>
Check the following specification of the sink device,: supported resolution, color space, color
depth (Deep Color) and whether audio and HDCP are supported.
■Checking operation using test patterns/tones (P.40)
Change the following settings of test patterns/tones to check the sink device operation.
(Default values are set for all settings.)
●Resolution
●The presence or absence of audio
●The presence or absence of HDCP
●Color space
●Color depth (Deep Color)

<If a test pattern is not displayed>
The sink device or cable 1 has a problem. Check the power supply, connection and input
switching (if there are some) of the sink device.
Perform the cable test (P.50) for cable 1 if necessary.
<If a test tone is not output to the sink device that supports audio>
Check the following items: volume of sink device, mute setting, the presence or absence of
headphones connection, and audio input setting.
<If there is no problem or test pattern is not displayed in a specific setting>
Perform the source test (②Fig. 3.3).
Immediately after the sink device and GF-100 are connected, the EDID of the sink device will
be copied into the GF-100 automatically. The copied EDID is used by the switcher during the
source test.
3.3 Source test
Test for switcher, distribution amplifier, BD player, cable 1 to 3 (P.19). Connect the switcher and GF-100 as

<If signals cannot be detected>
Check the power supply of the switcher, connection and channel switching setting. If the source
signals still cannot be detected, perform the sink test of the switcher (③Fig.3.4).
<If signals can be detected>
Check the following items: the resolution of the source signals, the presence or absence of
audio and HDCP, color space, color depth (Deep Color), and other items.
If source signals that are not supported by the sink device are sent, change the BD player
settings and EDID of the distribution amplifier, and other actions in order to resolve the problem.
If no problem is found, perform the sink test of the switcher (③Fig.3.4).

resolution of the test patterns/tones, the presence or absence of audio, the presence or absence of
HDCP, color space, and color depth (Deep Color).
<If a test pattern is not displayed>
Check the power supply, connection and input switching (if there are some inputs) of sink
device.
Perform the cable test (P.50) if necessary.
If the test pattern is still not displayed, perform ②above ([Fig. 3.5]).
<If a test pattern is displayed>
Check the following items: resolution of the test pattern, the presence or absence of audio and
HDCP, color space, and color depth (Deep Color) and then perform the source test.
■Checking source status (P.19)
Check if source signals are detected correctly. (P.21)
<If signals cannot be detected>
Check the power supply of the source device and connection.
<If signals can be detected>
Check the following items: the resolution of the source signals, the presence or absence of
audio and HDCP, color space, color depth (Deep Color), and other items.

We recommend that you copy EDID of the sink device in advance and set it to the source test connector in
order to acquire the same status as the actual operation.
If the EDID output mode (P.30) is set to “AUTO”(Default), connect the sink device to the sink test connector
