4K Touch


Did you install it successfully? I think it should be the problem of 4K touch screen. I also started the black screen, and then I couldn't install it.

First, unlock the CFG, then adjust the DVMT.

At present, there are some problems in my EFI: after waking up the computer after sleep, there is a certain probability that the keyboard can not be operated, and the shortcut key for brightness adjustment is abnormal.

Thanks. I'll try it now and answer right away. By the way, I also have a Catalina keyboard that doesn't work after sleep.
