Product Application

LED Indicator Description

1. Connect the HDMI-EDID emulator to the HDMI output of a computer graphics card or playback device. The red LED will flash, indicating it is waiting to read the EDID signal.

2. While the red LED is flashing, connect the HDMI cable to the target display. Once the screen is connected, the LED will turn purple for about one second, indicating it is learning the screen’s EDID information.

3. Once the LED turns solid blue, you can connect compatible peripherals such as projectors, KVM switches, HDMI switchers, or recording devices.
