So I had a little more time to try this and try adding an EDID manager in the mix.
I've tested this on 4 monitors and the same behavior.
I've tested this in production environment and the SDI run is only 60' from the SDI Dist amp. I tried this on 3 different monitors in the production environment.
The 4th monitor is on my desk isolated from the production network.
To simplify the setup, I've moved this test setup to my desk with a simple setup. Only a single monitor in the mix with a single HDMI->SDI and then SDI->HDMI converter in the test setup with only 1' of cable. Same behavior - HDMI Handshake fails.
I'm
only seeing this with the
new USB-C based Blackmagic SDI->HDMI converters. No issue with the JTECH & Monoprice ones I have in the toolbox.
Now what is interesting is if I add an EDID Manager between the laptop and the HDMI->SDI converter, then it works just fine with the BlackMagic converter.

This is really weird. Seems like a firmware issue to me since this seems laser focused on EDID issues.
