Purple Tint (DP port with DP to HDMI cable)

So, finally fixed black screen and multi-monitor issues after a day of much trial n error.

Thing is, on the DP port if I set connector type to 04 (DP) with DP to HDMI cable and HDMI monitor I get purple screen almost consistently. If I set to 08 (HDMI) all goes well. Unfortunately I don't own a DP monitor to test with straight DP cable.

It's a minor annoyance but having OCD+ADHD it bothers me. Does anyone have a fix for this?

I'm well aware this can be MacOS fault, own an MBP with Sonnet TB3 to dual DP ports and with active DP to HDMI adapters and HDMI cable purple screen occasionally happen after hot plugging.

Hack on Ventura, latest REL of OC also latest version for all required accompanying tools.

Thanks!
