MSI Z390-A PRO + i7-8700 > Monitor MHz Problem

[Carber]

Well it's always the same
It only does it on Mac OS, when I'm on Windows everything works fine.
I just tested on another screen, it works, it's weird.

When you tested the system on another display did you use the same cable?

You may need to add the following boot argument to your config.plist:

-raddvi

Which some cards need to Enable DVI transmitter correction (required for 290X, 370, etc.)

Good morning
Yes I used the same cable on the other screen.
And is there a way to have the bar activated to adjust the screen light because it is not activated?
Sincerely

Use the displays menu buttons/options to adjust screen brightness.

Use the displays menu buttons/options to adjust screen brightness.

I know but if you noticed it's not activating the light bar even in the optionsIt’s a desktop PC with an external screen.

I meant the controls on the actual Display, not the Apple display options.

This app might help.

-raddvi

I just tested -raddvi os launches but I only have 60 MHz and I no longer have 144 hrz

OK, it was a long shot as it is meant for older AMD dGPUs.

Remove it and try the App listed above.

Good evening
if I delete the -raddvi I will have the bug from before on the screen with lots of cloudy points

Well it seems you have a choice to make.

Use the boot argument and have 60Hz with the DVI cable or remove the boot argument and continue to troubleshoot the refresh rate issue.
