HDMI feed from Lightbridge 2 M600

Does anyone have a clue as to how I can get the Lightbridge 2 HDMI yo display onscreen in Litchi? I’ve tried to change the setting, doesn’t seem like it works. I’m running a CrystalSky with an M600 pro

The HDMI port on the Crystal Sky is for output only.

I specifically said from the Lightbridge. Page 1 of this question. I did figure it out. Thanks anyway.
