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).

[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.
