PSA: If you have a mac and an HDR monitor, do NOT update to macOS 10.5.4.
I repeat, protect your eyes and DO NOT UPDATE!
macOS Catalina 10.15.4:
- High Dynamic Range output to HDR10-compatible third-party displays and TVs connected with DisplayPort or HDMI.
How do I rollback macOS?
Found a fix! I changed the DisplayPort version of my monitor from 1.4 to 1.2. No more HDR.
