 | hello everyone. I have been using a laptop with Mac os big Sur for the second year without experiencing any problems. Over time, I wanted to use my HDMI port to connect a second monitor, but it doesn't work. I spent a lot of time, several times, reading all the forums and official manuals on the topic of "framebuffer patching", about port substitution in device properties, and everything related to it, but it did not give me any result. I'm asking for your help. Thank you. I am attaching a screenshot of the video adapter configuration. There is only one boot argument in the config to fix the backlight "-igfxblr" Hardware: CPU: Intel(R) Core(TM) i3-8145U CPU @ 2.10GHz Whiskey Lake-U GPU: Intel(R) UHD Graphics 620 (1 ГБ) RAM: KingSpec DDR4 8GB 2666MHz Motherboard/Laptop model: HP Pavilion Laptop 14-ce2001ur Audio Codec: Realtek ALC295 @ Intel Cannon Point-LP PCH - cAVS (Audio, Voice, Speech) [D0] Ethernet Card: Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter Wifi/BT Card: Intel Wireless-AC 9560 160MHz Wireless Network Adapter What guide/tool followed: https://dortania.github.io/OpenCore-Install-Guide/config-laptop.plist/coffee-lake.html#starting-point Opencore version 0.8.3 [link] [comments] |
