Here are a few suggestions:Recent Issue: I have a recent issue where both my monitors (LG 4K driven on DP from my Graphics card) go black, white or grey. The whole system freezes and has to be rebooted. It is training me to save often lol. Happens once a day or two days. I am using this a lot more than before though. It never happened prior to Catalina.

- Double check that all Hackintosh kexts have been removed from /Library/Extensions
- Install latest kexts in CLOVER/kexts/Other
- Update Clover to latest version (v5120) or try the new OpenCore 0.6.0 EFI (guide posted yesterday) by installing it on a USB flash disk (so that the main Catalina SSD is not affected)
- Check if the problem occurs if only one monitor is used or whether it occurs only when two monitors are used
- Remove RadeonBoost if you're using it
- If nothing seems to work, then it's a good idea to install a fresh copy of Catalina on a spare SSD (for example, a cheap 128GB SATA SSD mounted in a USB 3 enclosure) and check again
