Resolution Issue on Macbook Air M2

Hey Styrkinator,

We'd recommend reviewing the information in this article as the steps to address display issues may be helpful for your situation: If your external display isn't detected or appears blurry when connected to your Mac - Apple Support

"Adjust the resolution

1. From the Apple menu, choose System Preferences, then click Displays.
2. 
3. 
   
4. In Display Settings, select the external display in the sidebar, then press and hold the Option key while you click Scaled to see additional resolutions.
5. 
6. Select a resolution, then click Done.

If the expected resolution doesn't appear for your display, check the specifications page to see what display resolutions your Mac supports."

If that doesn't help, we'd suggest testing to see if the same issue occurs in safe mode, as that would help isolate the issue further. This article explains how: How to use safe mode on your Mac - Apple Support

"How to use safe mode

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

1. Shut down your Mac.
2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.
3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”
4. Log in to your Mac. You might be asked to log in again.

Intel processor

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in to your Mac. 
3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window."

Thanks!
