I’ll explore more now that I’ve got OpenCore on the MacPro. There are fixes for it in the Hackintosh world, but I haven’t run across one yet that might work on the MacPro.

The DP ports are much more reliable, plus the adapters are a lot cheaper than then MiniDP to HDMI one. Have you tried plugging in and unplugging? Also, you might want to try a MiniDP to DP adapter since your Card has a DP port. It has something to do with the HDMI output.

Solution for me, aside from adjusting the timing of monitor and computer sleep, unplug the HDMI port and plug it back in… after a minute or so, screen comes back up. If I tried to wake when only the monitor has gone to sleep, but the computer has yet to, then the monitor won’t come back on. However, if the computer goes to sleep as well and I wake the computer up, then the monitor will come back on. After monitor sleeps, can’t get the display back on.

To make sure my logic board is working, I replaced the GPU with the stock ATI Radeon HD 5770 1GB and boot with High Sierra - everything works fine.
