PiKVM DIY on Pi 4

Hello Everyone,
I finally went out and got a Raspberry Pi and installed PiKVM on it.
I am unfortunately having a hard time getting any video signal.
I have tried both the CSI bridge option/image and also tested with a USB to HDMI
converter I had lying around.

My source input is a new Mac Mini (Sequoia 15) and I changed the display to be 1080p + 50hz.

Browsing the support guide I see there is talk about EDID configs but I’m not sure what to start chasing first in terms of troubleshooting here.

Any help would be apprecaited.

Thanks!

Adding to my note on the console I see EDID block 0 is all zeroes repeatedly.
