I did some research and in some places it is said that it could be something with EDID and checking my configuration file (used in Catalina with Clover) it really has something in Graphics -> Custom EDID, but I don't know how to do this same configuration in Opencore, any idea how to do this? clover catalina config.zip

Even after apply this, the problem persists. I attached the config.plist with the suggestion applied and a picture of the problem. files.zip

Hi everyone, i made a clean installation of Mac OS Big Sur but i'm having problems with graphics. In Catalina everything worked fine, but when I boot i get some strange colors in my builtin monitor, but when I connect an external monitor(HDMI) the colors in the external monitor are OK. One thing I noticed is that when the laptop wake from sleep, the colors comes back to normal. Someone know how I can fix this? I'm using Opencore and attached my config.plist Laptop information: - Acer Aspire 5 A515-51G-70PU - Intel Core i7-7500U config.plist.zip
