misterdray Posted December 21, 2019 Share Posted December 21, 2019 I was successfully able to have 4 Monitors working in Catalina 10.15.1 and Sierra 10.12.6. These are connected to a ASUS ROG-STRIX-RX580-O8G-GAMING GPU. 3 are running in 1080p and 1 is running 1440p. I do have one issue though and maybe someone can give me a pointer on 3rd party software. The desktop backgrounds will never stay the same after restart nor will the daytime and night time setting. I will manually change them and when a reboot happens or I go to another OS, the desktop backgrounds just change. I've tried different things and even set it to not dictate the daytime or night time mode. Any ideas? Oh and I can load alot of websites, but www.STARZ.com refuses to load. Netflix, YouTube, other videos will load but not Starz. I have tried this only on Safari and Chrome. Quote Link to comment Share on other sites More sharing options...
