| No. | Name | Function Description |
|---|---|---|
| 1 | POWER LED | The blue LED will be on when the device is powered on. |
| 2 | IN LED | The blue LED will be on when a source device is connected. |
| 3 | OUT LED 1~8 | The corresponding blue LEDs will be on when display devices are connected. |
| 4 | SERVICE | USB Type C port used for firmware update. |
| 5 | EDID Dial Switch | COPY: Reads the EDID setting of the HDMI OUT 1 display device and sends it to the source device. The source device will then send a signal matching the OUT 1 display device to all HDMI outputs. AUTO: Compares the EDID settings of HDMI OUT 1~8 display devices, then sends the best EDID signal to the source device. The source device will then send a signal matching all connected display devices to all outputs. |
Rear Panel

|---|---|---|
| 6 | DC 12V | DC 12V/1A power input port. |
| 7 | HDMI IN | HDMI signal input port. Connect to an HDMI source device such as a DVD player or PC with HDMI cable. |
| 8 | HDMI OUT 1~8 | HDMI output ports. Connect to HDMI display devices such as a TV or monitor with HDMI cable. |
Auto Downscaling
This splitter supports resolution auto downscaling on all outputs. It will automatically output the proper HDMI signal according to the EDID of the display device.
COPY Mode: The source signal is sent to each output according to the EDID of the connected display device. 4K TVs receive a 4K signal; 1080p TVs receive a downscaled 1080p signal.

AUTO Mode: The EDIDs of all output devices are compared. The source signal is then downscaled and sent to all outputs based on the lowest common EDID detected across all connected displays.
