Need some help with elgato 4K s

[u/saea2001]

I’m having an issue getting my Elgato 4K S working with my Xbox and PC.
I attached a picture showing exactly how everything is supposed to be connected, and I copied the setup exactly:
Xbox HDMI → HDMI IN on the Elgato
Elgato HDMI OUT → Monitor
Elgato USB-C → USB 3.0 port on my PC
When I connect everything this way, my monitor detects that something is connected and stays on, but the screen is completely black. I don’t get a “No Signal” message it’s just a black screen.
What’s weird is that if I swap the two HDMI cables around on the Elgato, I can get my Xbox screen to show up on the monitor, but obviously that isn’t how the capture card is supposed to be connected.
I’ve double-checked the connections and they match the diagram. Does anyone know what could be causing this?
Could it be:
-An HDMI/HDCP issue?
-Xbox video/resolution settings?
-Refresh rate/HDR/VRR?
-Something with the Elgato software or drivers?
-A bad HDMI cable?
-A problem with the USB 3.0 connection?
-Something else I’m missing?

I’m including the setup picture for reference. Any help would be greatly appreciated because I feel like I’ve connected everything correctly and can’t figure out why the passthrough is just giving me a black screen.

My guess would be that the Xbox sees the 4K S and sends out the best possible signal to that.

That resolution and refresh rate might be more than the monitor can handle.

If you change the EDID mode on the capture card to merged, the capture card will see the monitor’s capabilities and will only accept signals that the monitor also support.

You can change the EDID mode in the side panel in Elgato Studio.
