10.15.5 HDMI依然黑屏

[cdqrain]

用最新版的EFI，HDMI还是黑屏，DP正常，是不是还是没解决？

参考楼上和[https://github.com//issues/11#issuecomment-639236174]，需要手动Fake ID
由于目前没有机器进行测试，所以无法进一步确定问题和给出更好的解决方案，抱歉

你的机器是这个mini主机吗？

用这个试一下，我后来是改了驱动，没有改config.plist

你这个是笔记本的，貌似还有点差别。

可以在此基础上改型号或者接口

用这个缓冲帧补丁，现在完美了。

我试了你这个EFI补丁,在只有一台HDMI显示器接入的情况下, 开机BIOS不黑屏, Clover和macOS预启动阶段也不黑屏, 但是进入到系统输入密码界面之后会黑屏, 此时需要盲输密码进入系统后重新拔插HDMI接口, 才能正常显示. 不知道你那里是否有这个问题.

用这个补丁后需要重新插拔一次HDMI，不过比原来黑屏好多了。
