Question 5

What connects to which port on the SP-HDMI1X8-18G?

Accepted Answer

Connect the HDMI source, such as a Blu-ray player or PC, to the single HDMI IN, and connect up to eight displays to HDMI OUT 1 through 8. Power connects to the DC 12V input.

Question 6

How is the unit powered?

Accepted Answer

It is powered by the included 12V/1A multinational locking power supply, which accepts AC 100-240V at 50/60Hz.

Question 7

Nothing appears on any of the connected displays. What should I check?

Accepted Answer

First confirm the POWER LED is lit blue, which means the unit has power from the DC 12V supply. Then check the IN LED is lit blue, which indicates the source is connected to HDMI IN, and finally check that the OUT LED lights for each connected display.

Question 8

One output stays dark while the others work.

Accepted Answer

Check that the OUT LED for that port lights when its display is connected, since each OUT LED 1~8 lights only when a display is present on that output. Then reseat the HDMI cable at both ends and confirm it is a Premium High Speed HDMI cable.

Question 9

My current splitter blanks every screen when one display is only 1080p. Does this fix that?

Accepted Answer

Yes. In COPY mode each of the eight outputs downscales on its own, so the 4K60 displays keep native 4K while a 1080p screen gets a 1080p feed from the same source. In AUTO mode the splitter compares all eight displays and sends one format they all accept, so every output runs 1080p when a 1080p disp

Yes. It passes the full 18Gbps HDMI 2.0 signal at 4K60 4:4:4, 8, 10 or 12-bit, with HDR10, HDR10+, Dolby Vision and HLG, to all outputs.
