My 5600XT just arrived and works super smoothly out of the box via HDMI, but it appears to be causing crashes of just one particular app - qBitTorrent when waking from sleep (many people report that it's happening only while using HDMI or MacBooks in clamshell mode connected to external display). I decided to try one of the 3 DisplayPorts instead and... nothing, the display (Philips BDM3270) doesn't get the signal from any of the DP ports (each time booting from scratch, not hot swapping). My previous GPU - RX560 worked fine with both DVI and HDMI - haven't ever tried DP.
I'm on 2012 5,1 with OC Catalina with HWaccel enabled - maybe that's the culprit? Some people on hackintosh forums report changing board ID to a different model works but i believe iMac Pro is the only one that works right now for OC? Or maybe it's as simple as a bad cable? I'm using a generic one that came with the display, but has never been used so doubt it's damaged.
