The display becomes strange after configuration

[Tamaki-sakuya]

Hi,

I have a Samsung G9 Neo G95SC monitor and the screen will be stretched from 16:9 to 32:9 when I connect with a Macbook M3 16inch, which is almost unusable.

So I do some changes by BetterDisplay, after one changes, the screen is disconnected and reconnected. But I found that the changes I made disappeared in the application interface, and the color and brightness of the monitor became very strange, with color difference and obviously darker.

I'm wondering if there is any way to revert the changes I made and restore this monitor's profile to factory settings?

What changes did you make? If it is a change that is on the display side (like changing picture mode etc), you need to reset the display. If it's an app made change, you can of course restore original settings: https://github.com/waydabber/BetterDisplay/wiki/Safe-mode,-app-reset,-app-removal

Thank you for your reply.

Actually I made some changes to the monitor in the app, specifically I changed its default panel resolution and the default resolution used. After I made the changes, the monitor went black and had the problem I described above.

It is worth mentioning that after this, two color profiles appeared in my macos settings, as if macos thought it was a new monitor.

I don't know what I should do to get it back to the original state.

And after my test, these two color files with the same name have different effects.

One of them (the current one, after modification) is darker, and the other (the original one before change) is brighter.

Not sure what happened. You can delete the color profiles, that won't have any adverse effects. If the overridden native resolution causes issue (which should only be done if the panel resolution is not properly reported or you intentionally want to change the default scale base timing - but the option must be valid according to the EDID), then you should follow the exhaustive reset procedure.
