My M1 Air screen flickers after upgrading to OS Ventura

Hi M1_Air_screen_flickers_Ventura,

We recommend that you try the steps in the following link since you’re having problems with your display flickering on your MacBook Air: If your Mac display doesn’t look right

In order to perform the troubleshooting actions we recommended via the article above, please read through and complete the steps in the section titled "If the display is flickering."

*If the display is black or dim: Try adjusting your display’s brightness.

*If images are too large or too small: Try adjusting your display’s resolution.

*If the colors don’t look right: Try using the display profile designed for your display. For example, if you’re using a Thunderbolt display, choose Apple menu  > System Settings, then click Displays  in the sidebar. (You may need to scroll down.) Click the pop-up menu next to “Color profile” on the right, then choose Thunderbolt Display. If that doesn’t work, try calibrating the display.

*If your display is blurry: Make sure your Mac has detected that display. Choose Apple menu > System Settings, then click Displays.

To see the Detect Displays button, press the Option key. Then click the button to detect the display.

*If the display is flickering: Make sure your Mac and display are connected to one another with good quality cables and adapters. You may also be experiencing interference from a nearby power line, a fluorescent light, a radio, a microwave oven, another computer, or another electrical device. Try relocating nearby electrical devices, or moving your Mac and display.

*If you see bright or dark spots on a flat-panel or Mac notebook computer screen: Your display may have pixel anomalies. If you suspect your Apple display contains a high number of anomalies, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device. 

*If none of these solutions work: If you have an Apple display and can’t correct the problem, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device.

The reason why we're recommending the steps above is because they will show you what to do if the image on your Mac display doesn't look right.

Please do not hesitate to reach out to us if you have questions or need additional support.

Thanks for using the Apple Support Communities.
