kaoskinkae Posted February 26 Share Posted February 26 (edited) I've been testing different configurations and booting with two monitors, checking which monitor the BIOS displays first. You can see my latest videos on that monitor. My next attempt involved connecting a DVI-HDMI cable to my LG TV (see photo). In this case, the first monitor, as predetermined by the BIOS, is Disport-HDMI-DVI, so the OpenCore menu appears in HDMI, the system boots, and both monitors display video. However, with DVI, the infamous pink screen appears. I've been looking for information on how to fix this, and if it's possible to do it via Intel, I have a video about it. The final conclusion is that it's not possible from Big Sur. I tried following a guide that creates some files that then need to be placed in the "Display" folder, but due to Tahoe's protection, it's impossible. If anyone has had this problem or is curious about a solution, please comment on this case.
