感谢楼主,实测有效,终于是修复了。不过要注意下,如果有之前使用了igfxcflbklt=1 这个启动参数,应该将其替换为-igfxblr
v1.4.6
Backlight registers fix replaces the previous Coffee Lake backlight fix and is now available on Intel Ice Lake platforms.
Boot argument igfxcflbklt=1 as well as device property enable-cfl-backlight-fix are deprecated and replaced by -igfxblr and enable-backlight-registers-fix.
Add max pixel clock override through -igfxmpc boot argument or enable-max-pixel-clock-override and max-pixel-clock-frequency device properties
Moved PNLF samples to OpenCore
Ins 7590友达的前天测试4K 60Hz可用,系统版本11.2 Beta版(20D5029f),在DeviceProperties加参数,友达屏需要把enable-max-pixel-clock-override,enable-backlight-registers-fix两个都加上才能驱动,否则黑屏,辛苦在您的Github中提醒下大家
