Causing issues with my S3 OLEDS. When both page buttons are pressed together to show monitor levels etc, the OLED displays as normal. Rest of OLEDS still full brightness with no contrast - unreadable.

Please can you leave us details. OS version, number of displays connected

Re: *******Don't install the new security update from Apple for Catalina or Mojave***
 

Catalina V10.15.7, 3 displays connected. S3 only, not using PTcontrol for iPad etc. Installed security update which caused problem. Working fine before then. Oleds work fine on startup, displaying AVID.

Crap ... too late ... completely Blanked out scribble strips on all 3 of my S1's. Is there an easy solution back back-reving OS (Mojave?)
