Solved Weird Graphics Issues

[Deleted member 16045]

Hello, After i failed installing Mounterey i tried it with High Sierra.

High Sierra is the Best Option Because its the Last OS That Supports my Radeon 4870 Graphics Card.

Now i have the Problem that macOS Says i have 2 Monitors Plugged in, But i dont.

The First Monitor is VGA-Monitor and the Other one is My Monitor.

Now the Other Strange Thing. Although it sees my Monitor my Monitor is Showed as the VGA Monitor.

And Another thing is, that macos says its an 4800, but it‘s an 4870.

If you need more Explanation just Ask For it.

Its very hard to Explain.

You can try this. Open a Terminal window and run the following,

sudo rm -Rf /Library/Preferences/com.apple.windowserver.plist

Then reboot and check.
