Mac Pro 2019 poor resolution output
Hello, I've got a Mac Pro 7,1 with an W5700x, and an Apple Cinema Display, that only displays resolution till 1280x720, ive tried everything in this list so far :
- Restarting
- Unplug everything and wait a couple of minutes
- Update to last macOS version
- Tried the display on a separate machine and it works at full 2560x1440
and the problem persists, any information would be really appreciated
