DIP Switch Operation

EDID Management
The Extended Display Identification Data (EDID) is used by the source device to match its video resolution with the connected display.
By default, the source device obtains its EDID from the first connected display.
Meanwhile, since the displays with different capabilities are connected to the splitter, the DIP switch on the front panel can be used to set the EDID to a fixed value to ensure the compatibility in video resolution.
The switch represents “0” when in the lower (OFF) position, and it represents “1” while putting the switch in the upper (ON) position.

Switch 1~3 are used for EDID setting. The DIP switch status and its corresponding setting are shown at the back of the product.

The switch represents “0” when in the lower (OFF) position, and it represents “1” while putting the switch in the upper (ON) position.

Switch Status	Video Resolution	Audio Format

000

| Obtain the EDID of output 1-2, then compare EDIDs and output the highest level of video resolution and the lowest color space.

Example: If there is 4:4:4 and 4:2:0 color space, it will retain the 4:2:0 after compare procession, and if there is 8K, 4K and 1080P, the machine will output the 8K resolution.

Note: The output EDID supports up to 8K@60 4:2:0
