Dual display with HDMI and DP #1

Open AKKYM opened 4 years ago

AKKYM commented 4 years ago

I used the contents of this repository to successfully Hackintosh with Deskmini 110+Mojave. It is possible to use a 4K monitor with DP.

We also added a monitor via HDMI to make it a dual display. At this time, MacOS recognizes the HDMI monitor, but a black screen is displayed.

Are you experiencing a similar problem? Also, how do you think these problems should be solved? If you can come up with a solution, I would appreciate it if you could tell me. Thank you very much.

@AKKYM try to power on with only DP port monitor plugged in. when you enter macOS, plugged in the HDMI monitor.

In my environment, when the monitor is plugged into the DP and HDMI ports and turned on, the DP monitor will be displayed correctly, but the HDMI monitor has a black screen.

If the monitor is plugged into the DP port only and then turned on, and then plugged into the HDMI port, the DP monitor will be displayed correctly, but the HDMI monitor will turn black.

When the monitor is plugged into the HDMI port only, turn on the power, and then plug the monitor into the DP port, both monitors will be displayed correctly.

In this case, the monitor used for the DP port is a 4K 60Hz monitor, and the monitor used for the HDMI port is a FullHD 60Hz monitor.

I want both monitors to display properly when plugged into both ports and turned on. Do you know what the solution is?
